The current MRCPsych is an example of summative assessment: trainees sit the two parts at specific stages during their training and the grades they attain form the basis on which decisions are made about their future. Since the MRCPsych leads to a professional qualification it is also a high-stakes exam. By contrast, formative assessment is typically undertaken to provide feedback to the trainee and their educational supervisor about progress and potential difficulties but without contributing to pass/fail decisions. A recent trend in medical education is to soften the distinction between formative and summative assessment (Postgraduate Medical Education and Training Board, 2005) as the emphasis moves away from performance in high-stakes exams to gathering evidence of clinical competence and appropriate professional behaviour and attitudes. The Postgraduate Medical Education and Training Board (PMETB) argues that this evidence is best gathered in the workplace through workplace-based assessments.
Educational assessments should fulfil two particular requirements. First, the assessment should be reliable: it must produce consistent results. Second, it should be valid: it should measure what it is supposed to measure (Newble & Cannon, 2001). Any one method of assessment will have good and bad points. Therefore the best way to build up a complete picture of a learner is by combining a number of different assessments, each of which tests different areas of learning (Schuwirth, 2004). Thus, the current MRCPsych includes multiple choice questions (MCQs), objective structured clinical examinations (OSCEs), patient management problems (PMPs), essays and individual patient assessments (IPAs).
In its new format, which will be introduced in Spring 2008, the MRCPsych written papers will retain the MCQ and OSCE, but drop the essay, PMP and IPA in favour of the EMQ (extended matching question: see below). To these formal exams, and in keeping with the requirements of PMETB, will be added several methods of workplace-based assessment during the course of training. As these assessments involve personal witnessing of trainees interactions with patients over a period of time and in a variety of settings, they are thought to have high face validity (Brown & Doshi, 2006). Nevertheless, questions have arisen about the appropriateness of using workplace-based assessments, as they do not have published reliability data for psychiatry in the UK (Rose, 2006). To obtain such data the Royal College of Psychiatrists has carried out a pilot project across 15 sites and involving over 600 trainees. Preliminary results are being analysed at the time of writing.
Thus, the formal exams should preserve confidence in psychiatric training, while the MRCPsych as a whole conforms to PMETBs overarching assessment strategy consisting of workplace based assessment, and examinations of knowledge and clinical skills (Postgraduate Medical Education and Training Board, 2005). The MRCPsych therefore is part of the whole assessment package for development of trainees.
| Why run revision courses? |

Learning styles
A key concern about revision courses is the type of learning that they can encourage. Newble & Entwistle (1986) divide learning styles into strategic, surface and deep learning. Strategic learning is motivated by a desire to be successful, and leads to patchy and variable understanding. Surface learning is motivated by fear of failure and a desire to complete a course: students tend to rely on learning by rote and focusing on particular tasks. Many feel that it is precisely these types of learning that revision courses use. In deep learning, however, individuals are motivated by their interest in the subject matter. They learn because they believe what they learn to be relevant and they are rewarded by acquiring knowledge that helps them to carry out tasks that matter to them. Deep learning is active rather than passive and it involves interaction with others (Gibbs, 1992). Deep learning is more likely to be associated with a better quality of learning (Oxford Centre for Staff Development, 1992).
Assessment-driven learning
We know that assessments drive the way in which learners study (Frederiksen, 1984; Misch, 2002). Ideally, assessments should match the aims and objectives of the curriculum, so that studying for exams becomes the same as studying to become a better doctor (Schuwirth, 2004). This view is implicit in recommendations that psychiatric trainees in Canada should sit regular mock exams throughout their training (Crockford et al, 2004). These incorporate training in case vignettes, oral examination skills and anxiety management skills. It is also implicit in the Colleges new competency-based curriculum and its emphasis on workplace-based learning and workplace-based assessments (Bhugra, 2006).

Box 1 Things to do when setting up MRCPsych revision courses
|
Although the revision courses are part of the Birmingham MRCPsych preparation course, trainees are charged a nominal fee to cover the cost of lunch and also to reduce the non-attendance rate. Any spare places on the course are offered at cost price to trainees from outside the region.
| Recruiting and retaining examiners |
|---|
|
|
|---|
A word of caution is necessary, in that examiners may be party to information that should not be divulged to trainees, for instance examiners must not remove any examination material from the OSCE stations during the College exams. Consultants who are involved in setting or organising exams for the College need to be particularly careful.
At Birmingham, revision courses take place on a Saturday and can involve a considerable amount of extra work. We have found that paying the examiners helps minimise non-attendance.
| Organising revision courses for written examinations |
|---|
|
|
|---|
All three papers of the new MRCPsych will contain MCQs with a 1 from 5 single best answer format, that is the candidate will have to select the most likely answer out of five options, some of which may be correct but one of which is more likely to be correct than the others. This is different from the current MRCPsych, which has individual statement questions (ISQs) individual statements are presented, each of which has to be marked as true or false. It is assumed that the new format will reduce the chances of guessing the correct answer. These changes are on-going and readers are strongly recommended to keep up to date with information on the College website (http://www.rcpsych.ac.uk).
Extended matching questions
The three written papers of the new MRCPsych will each also include extended matching questions (EMQs). The EMQ (also know as the extended matching item (EMI) question) is a variant of the traditional MCQ, and it is increasingly becoming the preferred format for written undergraduate and postgraduate medical examinations. In an EMQ the stem is typically a clinical scenario about which related questions are asked. Candidates must choose their responses from a list of at least 5 options (usually 1020 are offered). If, for example, 10 options are given, the candidate is likely to guess correctly only 10% of the time (George, 2003), and this minimises the recognition effect that occurs in standard MCQs. By using clinical vignettes instead of facts, the items can be used to test the application of knowledge or clinical reasoning (Case & Swanson, 1993; Schuwirth & van der Vleuten, 2004). Another advantage of EMQs is that they are perceived as being the fairest examinations (McCoubrie, 2004).
The EMQs are often written in sets, to be used together in the same exam, where the same theme and option list is used for two or more different vignettes. Case & Swanson (2002) have described how EMQs can be constructed, and the steps involved are outlined in steps 15 below, using as an example a pilot EMQ produced by the Royal College of Psychiatrists (Box 2
).
| Box 2 A sample EMQ produced by the Royal College of Psychiatrists Theme: Disorders of perception Options:
Lead in: Which of the above descriptive psycho-pathological terms refers to the following symptoms? 37) I hear the voice of my long dead father, as if he were talking to me now, when I hear water running from the bath tap. 38) I hear the voice of my father speaking to me from the other side of the city. 39) A young woman describes looking up into the clouds and seeing an image of her fiancé. 40) A 22-year-old woman with schizophrenia describes the sensation that somebody is touching her body in intimate places. Answers: 37 E 38 D 39 H 40 F
|
1Decide on the theme for the set
The theme could be a presenting problem (e.g. low mood), a situation (e.g. admission/discharge from the emergency department), or a drug class (e.g. atypical antipsychotics). In the example in Box 2
it is disorders of perception.
2Write the lead-in for the set
The lead-in indicates the relationship between the stems and options, clarifying the question posed. In the example it is Which of the above descriptive psychopathological terms refers to the following symptoms?
3Prepare the list of options
The options should be single words or very short phrases; they should be listed in alphabetical order unless there is an logical alternative order.
4Write the items or stems
The items within a set should be similar in structure: in the example they are the description of symptoms. Often they are patient vignettes.
5Review the items
A check should be made to ensure that there is only one best answer for each question. There should be at least four reasonable distractors (incorrect options) for each item.
MCQ and EMQ revision
At Birmingham, revision for this part of the exam takes place throughout the MRCPsych course, as course speakers are encouraged to produce questions as part of their lectures. In addition, during the Part I course 4 hours are devoted to MCQs and EMQs. During these sessions MCQs and EMQs linked to the teaching of that semester are introduced and answers are discussed.
Practice MCQs are available on various websites and also from numerous books (e.g. McNamara, 2003; Michael, 2004a). Shortly before trainees sit the Part I written paper they sit a half-day mock exam under examination conditions. The candidates mark each others papers and the course leader oversees a brief discussion of the answers. The subject matter of the mock exams should reflect the structure of the College examination (see the College website for details: currently http://www.rcpsych.ac.uk/exams/regulationsandcurricula/examregulations/examformat.aspx). An important part of the revision is not only to get trainees used to the format of MCQs and EMQs but also to encourage interactive discussion of possible answers.
Speakers on the Part II course are also encouraged to discuss MCQs with the trainees as part of their lecture. The Part II Written Revision Day includes a 1-hour session going through selected MCQs.
As the three knowledge-based papers of the new MRCPsych will contain only MCQs and EMQs one would assume that there will be greater demand from trainees for MCQ and EMQ practice in revision courses. Furthermore, training for assessors of workplace-based assessments will certainly emphasise preparing trainees for this assessment and there may also be a demand for this in revision courses.
Essay papers and critical appraisal questions
The current Part II written exam contains an essay paper, and essays are a good way of assessing a students ability to summarise and integrate information, as well as to hypothesise, find relations and apply known procedures to new situations (Schuwirth & van der Vleuten, 2004; Tyrer & Oyebode, 2004). They do suffer from limited reliability and are expensive to mark (Schuwirth & van der Vleuten, 2004). There is no direct replacement for the essay paper in the new MRCPsych.
The introduction of the critical appraisal paper in the written Part II examination some years ago seems to have had a positive effect on the way journal clubs are run in psychiatric hospitals (Taylor & Warner, 2000). Paper 3 of the new MRCPsych will test the critical appraisal of research relevant to clinical practice, but in EMQ and MCQ format. The advantage of this will be that the paper can be marked reliably and without bias. As part of workplace-based assessments, trainees will also have to do four journal club presentations during the course of their training. This is another example of the power of assessment to drive student learning. Brown & Wilkinson (2005) and Ogundipe et al(2005) provide a guide to critical appraisal papers.

Recruiting simulated patients
Many medical schools now have a pool of people that are used as simulated patients for exams and teaching. Simulated patients are often actors, drama students or even members of amateur dramatic societies. Developing a bank of simulated patients solely for use in revising for exams would be extremely time-consuming (Ker et al, 2005) and it is better to tap into an already existing resource. A professional agency is used for the Birmingham MRCPsych revision courses.
Preparing simulated patients
Simulated patients participating in a mock OSCE receive vignettes in advance. Its important to make explicit what information these individuals are expected to volunteer and how they are to divulge it. Before the OSCE begins a briefing should emphasise the need for consistency in the simulation for all candidates and should also allow them the opportunity to clarify any points in their instructions. Floating external examiners can be used to verify the accuracy and consistency of the simulations during the exam. A debriefing of simulated patients after the exam is also useful for the course organisers, in planning future courses and giving feedback to trainees.
Feedback to candidates from mock clinical exams
For trainees feedback provides invaluable information about how they might improve their performance. All examiners should be aware of how to give feedback in a manner that allows the trainee to feel safe. Teaching the teachers courses are a good way to disseminate these techniques (Vassilas et al, 2003). Although they have been criticised (Walsh, 2005), Pendletons rules (Box 3
) are a useful starting point in this regard.
Box 3 Pendletons rules
|
Building on Pendletons ideas teachers at the University of Calgary Medical School developed the framework of descriptive feedback (Silverman et al, 1996; Kurtz et al, 1998). Devised to help with teaching communication skills, this offers more specific guidance and techniques for giving feedback in a non-threatening manner (Vassilas & Ho, 2000). The essential components of descriptive feedback are listed in Box 4
. The learner is assisted in finding a solution to any difficulties that arise by using as a starting point the problems that they themselves experience. A non-judgemental approach is used and the feedback describes what actually happened. During this session the focus is on desired outcomes and trainees are asked what they want to achieve. Feedback is balanced, in that comments are made about things that worked and things that did not, but the strict order required by Pendletons rules is not necessarily followed. Trainees are encouraged to say what steps might be helpful next time. This latter point is particularly important in a revision course setting: frequently trainees want to know the correct answer, but in an examination as in a real clinical situation there may be no single correct approach. For the OSCE feedback sessions at Bimingham we try to get the group of trainees to suggest how problems that have arisen might have been better managed.

OSCEs
The OSCE was first introduced into undergraduate medical teaching at Dundee Medical School (Harden et al, 1975; Harden & Gleeson, 1979). It has become ubiquitous in both undergraduate and postgraduate medical exams (Adamo, 2003). The OSCE became part of the MRCPsych in 2003, following an evaluation of the MRCPsych examinations by a medical educationalist (Tyrer & Oyebode, 2004).
The OSCE format allows a wide range of skills to be tested and reduces the influence of any one examiner on the overall outcome for the candidate (Wallace et al, 2002). The OSCE is a test of clinical skills that is independent of factual knowledge, and foreknowledge of the stations does not appear to influence performance (Wilkinson et al, 2003). In an OSCE examinees move through a series of stations at which various clinical tasks are carried out. These tasks are observed and scored by an examiner. Reliability is increased with a larger number of stations (Newble & Swanson, 1988; Van der Vleuten & Swanson, 1990).
Smee (2003) outlines three areas that limit the extent to which OSCEs can be used to assess clinical practice. First, time-limited stations often require trainees to perform isolated aspects of the clinical encounter. This deconstructs the doctorpatient interaction and for formative assessments may be inappropriate. On the other hand, limiting the time means that there can be more stations, allowing for reliable, summative decision-making, which is how they are used by the Royal College of Psychiatrists. Second, OSCEs rely on checklists, and this assumes that clinical interactions can be described as a list of actions. Checklists tend to emphasise thoroughness, which may become less relevant as the clinical experience of candidates increases. Hodges et al(1999) confirmed that OSCEs were not so good at assessing advanced psychiatric skills. Third, there are limits as to the type of clinical scenario that can be portrayed in an OSCE. Again, this becomes more of an issue for advanced trainees.
An OSCE station can be broken down into the following four components (Tyrer, 2005).
The construct or stem
The construct states the aims of the station.
The objectives or checklist
The objectives are the actions that should be taken in response to the information in the construct. The items should be (a) appropriate for the level of training being assessed, (b) task-based and (c) observable (so they be scored). A score must be assigned to every item, and in the MRCPsych scoring is on a scale from A to F (F is a severe fail). Individual items are assigned different relative weights, with items considered more important being worth more. Using such weighting may improve the validity of an individuals score in an OSCE, which may affect which candidates pass or fail while at the same time not changing the overall pass rate (Smee, 2003).
Instructions to candidates
Any relevant background information is given and the candidates task is clearly stated.
Instructions to simulated patients
The approach to this is described above.
Box 5
shows extracts from a sample OSCE. The current MRCPsych Part I OSCE, with its 12 stations, shows high levels of reliability (Oyebode, 2002). The new format clinical examination will be an OSCE consisting of complex cases in two parts held on the same day. The first part will contain 10 stand-alone stations, each lasting 8 min (including reading time of 1 min). The second part will contain five pairs of linked stations, which will allow the assessment of more complex competencies, each station lasting 12 min (including 2 min for reading and preparation).
| Box 5 Extracts from an example OSCE The construct The candidate demonstrates the ability to establish rapport with a distressed relative and to explain the aetiology, nature, signs and symptoms of schizophrenia, its treatment using both pharmacological and psychosocial methods, in a way that the relative understands, and balances accurate and realistic information with instillation of hope. Instructions to the candidate This lady, Mrs Bennett, is the divorced mother of one of your patients, Stephen Bennett, who is a 21-year old university student recovering from a recurrence (second episode) of a schizophrenic illness. This first presented with an acute onset 3 years ago... Explain the nature of schizophrenia and the long-term prospects for her son. (Royal College of Psychiatrists, http://www.rcpsych.ac.uk/exams/regulationsandcurricula/examregulations/examformat/partiosce/sampleinstructions.aspx)

Part I clinical revision courses
Two different ways of organising revision for OSCEs have been described the OSCE workshop (Naeem et al, 2004) and the mock OSCE (Pryde et al, 2005). A comprehensive revision course will have elements of both types of revision. In the Birmingham MRCPsych Part I preparation course half a day per semester is dedicated to an OSCE workshop, and there is a separate mock OSCE revision course, held twice a year shortly before candidates sit the OSCE component of the MRCPsych.
OSCE workshops
In the OSCE workshop described by Naeem et al(2003) six candidates were divided into two groups of three, each group having a facilitator. After the the facilitators had described how OSCEs work they role played a sample station. Each group then tried out a station that it had designed on members of the other group. Finally, the trainees were given a copy of their marks and feedback was given. In this type of OSCE workshop trainees get experience designing their own stations and take responsibility for their own learning.
Mock OSCEs
While the OSCE workshop provides practice for the contents of the various stations, a mock OSCE is a rehearsal of the format of the exam, allowing practice of essential skills such as time management, thinking on ones feet and moving on from a difficult station.
Pryde et al(2005) have described in detail the organising of a mock OSCE. On the Birmingham MRCPsych revision course the mock OSCEs are held after the results of the written paper have been published and before the actual OSCE. The venue should be large enough to allow separate rooms for each of the stations as well as rooms for waiting and the briefing of the simulated patients. The Birmingham MRCPsych course uses a hospital out-patient department.
Examiners must be warned not to interact with the candidates apart from asking them their name and candidate number, unless the station demands it, and to resist the temptation to teach.
Designing the circuit
The circuit should closely mirror the format of the actual OSCE, with the same number of stations and the same timing for each station. Providing rest stations, that is stations with no examiner where the candidates sit down for 7 min, will allow for extra candidates and for the use of paired stations, where the content of the second station is linked to that of the first. To avoid confusion, it is essential to have successive stations in adjacent rooms and to make it clear to candidates where they should go. A wide variety of stations should be used, testing the five skills listed in Box 6
. There are a number of books giving sample stations (e.g. Michael, 2004b; Murthty, 2004; Rao, 2005) as well as internet resources.
Box 6 The five skills tested in the OSCE
|
In Birmingham, simulated patients are used for at least half of the stations. For the rest we use senior house officers who have passed Part I, teaching dummies, investigation results, etc.
Mark sheets can be designed for each station using the one on the College website (http://www.rcpsych.ac.uk/pdf/osce.pdf) as a template. The construct of each OSCE should be clearly specified, and the testable task should then be broken down into several components, each of which is graded on a 5-point scale. For most stations, communication skills will be a component.
Timekeeping
At least one facilitator should be assigned the responsibility of timekeeping. Several software programs available on the internet allow computerised timekeeping, with recorded voice instructions that simulate exam conditions. Having a stop watch and bell in reserve is essential.
Feedback
Before the mock OSCEs at Birmingham there is a discussion with the examiners and simulated patients on how best to give feedback. The examiners are encouraged to discuss each candidates performance with the simulated patient and to write down their comments using the principles of descriptive feedback outlined above. Feedback should say what was done well in addition to what could be improved on. After the mocks, trainees receive a copy of this written feedback. There is then a plenary session involving the simulated patients, examiners and trainees. Each examiner and simulated patient in turn gives feedback about how the trainees in general performed at their station, saying what was done well and what could have been improved on. The trainees then have an opportunity to question the examiners and simulated patients and to comment themselves on how best to approach the station. Offering feedback to learners immediately after they have completed the stations can improve competency in the performance of criterion-based tasks, at least over the short term (Hodder et al, 1989).

A major drawback of the IPA is its lack of reliability. Each candidate would have to see several long cases with several different examiners to achieve the level of reliability appropriate for a high-stakes examination and this is clearly not practical. Consequently in the new MRCPsych format the formal IPA examination will be replaced by an equivalent workplace-based assessment in the assessed clinical encounter (ACE). Each candidate will have to complete a minimum of eight ACEs during the course of their training. Three of these will be assessed by a validated College-approved assessor, and the marks will count towards the final clinical mark of the OSCE as part of a summative assessment.

The PMP format is subject to the same reliability problems as the IPA, despite the Colleges attempts to standardise them across the various examination centres in the country. Consequently PMPs have also been dropped from the new MRCPsych. However, we believe that it is wrong to assume that the workplace-based assessment methods of the case-based discussion or mini-ACE are equivalent to the PMP.

The new curriculum currently comprises a core and general module, together with modules for each of the six psychiatric specialties: adult; child and adolescent; forensic; learning disability; old age; and psychotherapy. PMETB has provisionally approved each of these modules. Additional modules on neuropsychiatry, liaison psychiatry, and social and rehabilitation psychiatry are under development and further modules are planned for the future.
Pilot studies of the curriculum are taking place in deaneries across the UK, supported by locally run workshops and by a package of supporting materials the Pilot Pack. The latter can be downloaded from the College website (http://www.rcpsych.ac.uk/training/curriculumpilotpack.aspx) and it contains the new curriculum itself.
The formal examinations: Papers 13 and the OSCE
The new examination and assessment programme combines formal MRCPsych exams with workplace-based assessments. The distinction between Parts I and II of the current MRCPsych has been replaced with a modular approach. There are three knowledge-based papers (Papers 1, 2 and 3), containing MCQs (1 from 5 single best answer) and EMQs, and a clinical exam in the form of an OSCE. Each component requires candidates to have achieved certain competencies at specified levels in their workplace-based assessments. The eligibility structure can also be downloaded from the College website (http://www.rcpsych.ac.uk/pdf/MRCPsych%20Assessment%20Programme%20Final%2020of3.pdf).
Paper 1 will be a basic paper assessing areas such as history-taking, treatment explanation and record-keeping. Paper 2 will be a more specialist paper focusing on areas such as psychotropic drugs, advanced psychology and neuropsychiatry. Paper 3 will contain complex questions assessing clinical specialties (including general adult psychiatry as a specialty) and critical appraisal of research relevant to clinical practice. Table 1
shows the contents of the three written papers. The approximate percentage of a paper allocated to each area will be published in due course.

Workplace-based assessments
The College has established four principles for workplace-based assessments:
| Implications of the new programme |
|---|
|
|
|---|
The new examination and assessment programme presents a challenge to organisers of MRCPsych preparation and revision courses. The standard lecture format of most preparation courses looks increasingly obsolete. As already mentioned, there will be increased demand for MCQ, EMQ and OSCE revision. There will also, no doubt, be an increased demand for revision courses aimed at workplace-based assessments, leading to the paradox that the introduction of assessment methods to measure performance in the workplace will drive the need for training in these methods outside the workplace.
Course organisers need to be aware that in June 2005 it became mandatory for psychiatric trainees to receive training directly from service users and carers (Fadden et al, 2005). The vision of the College is that service users and carers should be involved in the planning, delivery and evaluation of psychiatric training as well as the assessment of psychiatric trainees.

If revision is provided uncritically it may result in strategic learning. Thus, an important part of the process is to ensure that those running feedback sessions use the approaches outlined above. The traditional lecture, which is still used in many MRCPsych courses, can be improved by using interactive lecturing (Steinhert & Snell, 1999). Incorporating MCQs or even OSCE stations into the MRCPsych revision courses may, if they are used as the basis for discussion, improve the educational value of the courses.
Organisers of MRCPsych courses should help learners to pass the examinations but do so using the principles of adult learning. Giving the trainees the tools to learn themselves and encouraging a deep approach to learning should mean better training for trainees.
The new examination and assessment programme will alter the way preparation and revision courses are run, but experience gained with running the current MRCPsych courses will not be wasted as the same educational principles still apply.
