Poorly selected assessment methods can lead to passive or rote learning (to get through an exam ination), which is associated with a rapid decay of knowledge and sometimes an inability to apply it in real situations (Stobart & Gipps, 1997). The main components of undergraduate and postgraduate assessment in medicine have traditionally been written and clinical examinations. These have strengths and weaknesses. The majority are now better in an all-round sense in that they test a number of dimensions, for example knowledge, problem-solving and communication skills, but by definition they are still one-off assessments. A single, sometimes non-clinical, event establishes what a doctor knows (e.g. in a multiple choice paper), knows how to do (e.g. in a short-case viva or extended matching questions) or is able to show how to do on the day (e.g. in a long case or an objective structured clinical examination, an OSCE). They are basic tests of competence, not assessments of day-to-day performance. They specifically do not assess other attributes necessary for a person to perform consistently well as a doctor, for example team-working skills.

The current shift in medical education is towards outcome-based learning. Outcome-based education can best be summed up as results-oriented thinking. It is the opposite of input-based education, where the emphasis is on the educational process, almost regardless of the result. In outcome-based education, the outcomes agreed for the curriculum guide what is taught and, importantly here, what is assessed. Exit outcomes, i.e. the doctors performance capabilities, are therefore a critical factor in determining both what is to be learnt (the curriculum) and what is to be tested (the assessments). Assessment programmes in outcome-based education must be systematic and include criteria for each of the abilities defined.
The focus is on the care delivered to different patients and in different settings.
Newer assessment methods need to be able to assess what a doctor actually does in everyday practice (Miller, 1990), rather than one-off assessments of what they know, know how or can show how (Fig. 1
). This requirement has led to the rapid development of suitable assessment tools and schedules, generally brought together under the title of workplace assessments.

All assessment systems and, indeed, curricula must now satisfy PMETBs published requirements (Postgraduate Medical Education and Training Board, 2004a,b).

To ensure that the right competencies are learnt and validly and reliably assessed, workplace assessments in psychiatry, as in medicine in general, need to be considered alongside the development of curriculum models. The clear advantages of assessment in the workplace include the opportunities for feedback and the educational value conferred by putting emphasis on real-time assessment. It is a strange fact of medical life that trainees are infrequently formally observed in daily encounters with patients. This limits the opportunity for continuous and developmental feedback on clinical performance. The introduction of assessment in the workplace means that far greater emphasis can be placed on patient-based learning and far more detailed, valid and reliable observations of doctors clinical performance can be obtained.
It is well documented that assessment drives learning (Broadfoot, 1996). Thus, if Dr A, a senior house officer, is assessed only by a multiple choice paper, she is likely to direct her learning towards facts from books. If she is assessed in the workplace, she is more likely to focus her learning on patient-based activities.

A further important reason for using different types of assessment is the specificity of the various assessment tools themselves. The development of a competency-based approach to training sets the most challenging agenda of accurately assessing a student both in individual components of competency and in overall performance.
Much of the existing data on the use of workplace-based assessments is derived from other medical specialties and often from other countries (Norcini et al, 1995). In psychiatry, we must develop or adapt existing assessment methods and assessors in order to produce accurate and defensible data.
The strategy of using multiple assessments could quickly become burdensome, since the gold you might say platinum standard would be one of infinite measurements applied daily by everyone involved with the trainee. A compromise will have to be reached between a method that gains sufficient information to draw a full picture of the trainees developing performance and the need to run services on a daily basis.
The picture emerging in the UK is based on PMETBs curriculum for the foundation years of postgraduate education and training, the core competency requirements of which are summarised in Table 1
. The assessment system will take a three-tiered approach, encompassing educational (not National Health Service) appraisal, assessment and annual review (Postgraduate Medical Education and Training Board, 2005).

The mini-CEX (Norcini et al, 2003) involves several assessments, each of 20 min duration, that are conducted at intervals during training. Each clinical encounter is selected to focus on areas and skills selected from the foundation curriculum (Foundation Programme Committee of the Academy of the Medical Royal Colleges, 2005) (see Table 1
). A trainee will undertake six to eight mini-CEXs over the course of foundation-level training (Table 1
). Each assessment will be rated by a single but different examiner and will assess skills not previously examined. Rather than completing a full history and examination the trainee is asked to conduct a focused interview and examination, for example to assess the suicidal intent of a patient. Assessment takes place in settings in which doctors would normally see patients (out-patient clinics, on the wards) and immediate direct feedback is given to the trainee.
The mini-CEX has been demonstrated to have good reproducibility (Norcini et al, 1995), validity and reliability (Kroboth et al, 1992; Durning et al, 2002; Kogan et al, 2003) in general medicine.
The number of mini-CEXs required in higher specialist training is yet to be determined. The studies on reproducibility suggest that, for a given area of performance, at least four assessments are needed if the trainee is doing well and more than four if performance is marginal or borderline (Norcini et al, 1995).
As yet the mini-CEX has not been evaluated specifically with psychiatric trainees. Early experience suggests that the practical planning (e.g. coordinating diaries to book the session and to give time to find a case that meets the criteria) should be done well in advance. The time required for an assessment stated in the foundation-years curriculum (Foundation Programme Committee of the Academy of Medical Royal Colleges, 2005) may be an underestimate and resources are required in terms of time and patients. Importantly, the examiners will require extensive training.
The standardised patient examination
A standardised patient is a person who is trained to take the role of a patient in a way that is similar and reproducible for each encounter with different trainees. Hence they present in an identical way to each trainee. The standardised patient may be an actor, an asymptomatic patient or a patient with stable, abnormal signs on examination. Standardised patients can be employed for teaching history-taking, examination, communication skills and interpersonal skills. They can also be used in the assessment of these skills. The advantages of using standardised patients are that the same clinical scenario is presented to each trainee (reliability) and they enable direct observation of clinical skills (face validity). Feedback can be immediate and can also be given from the point of view of the patient although the standardised patient would need to be trained to do this in a constructive manner.
Using standardised patients has high face validity. Reliability varies from 0.41 to 0.85 (Holmboe & Hawkins, 1998), increasing with more cases, shorter testing times and less complex cases. The reliability of this type of assessment is better when assessing history-taking, examination and communication skills than for clinical reasoning or problem-solving. Standardised patients have been used in multi-station exams such as OSCEs, where trainees perform focused tasks at a series of stations.
Standardised patients have been used as a means of integrating the teaching and learning of interpersonal skills with technical skills and giving direct feedback to trainees. If the studentpatient encounter is video recorded the student can subsequently review the tape as an aid to learning (Kneebone et al, 2005). Video recordings can also be used as part of a trainees assessment, for example by enabling multiple raters to assess the individual (thereby increasing reliability). For workplace-based assessments the standardised patient would be seen in a setting where the candidate normally sees patients.
Case-based discussion
Case-based discussion is also known as chart-stimulated recall examination (Munger, 1995) and strategic management simulation (Satish et al, 2001). The trainee discusses his or her cases with two trained assessors in a standardised and structured oral examination, the purpose of which is to evaluate the trainees clinical decision-making, reasoning and application of medical knowledge with real patients. The assessors question the trainee about the care provided in predefined areas problem definition (i.e. diagnosis), clinical thinking (interpretation of findings), management and anticipatory care (treatment and care plans) (Southgate et al, 2001). The trainee is rated according to a prescribed schedule; a single examination takes about 10 min, and there will be about six to eight examinations during the course of training. The assessors (two independent raters) visit the trainees place of work and the patients notes/trainees documentation are used as the focus of the exam.
Patients must be selected to form a representative sample. The trainees performance is determined by combining scores from a series for a pass/fail decision. Reliabilities of between 0.65 and 0.88 have been reported in other medical specialties (Accreditation Council for Graduate Medical Education & American Board of Medical Specialties, 2000). Assessors must be trained in how to question and how to score responses.
Case-based discussion is potentially easy to implement but it requires that trainees manage sufficient and sufficiently varied cases to give a valid and reliable sample. Extensive resources and expertise will be required to standardise the examination if it is to be used for high-stakes assessments.
Directly observed procedures
Directly observed procedures or objective structured assessment of technical skills are similar to the mini-CEX. The process has been developed by the Royal College of Physicians to assess practical skills (Wilkinson et al, 2003). Two examiners observe the trainee carrying out a procedural task on a patient and independently grade the performance. This form of assessment lends itself well to medical specialties where the acquisition of practical skills is important. Examples include suturing a wound, taking an arterial blood sample and performing a lumbar puncture.
In psychiatry it is less obvious what we would observe because psychiatrists are less involved with practical procedures. One possibility would be assessing how a trainee administers electro-convulsive therapy (ECT), but this is not frequently prescribed. Alternatively it could be used to assess less concrete skills such as conducting a risk assessment on a patient who has recently taken an overdose or preparing a patient for ECT, explaining the process and obtaining consent. In practice, there could be considerable overlap with the mini-CEX.
Multisource feedback
The need for a measure of the humanistic aspects of a doctors practice is increasingly accepted. Multisource feedback, which is also known as 360° assessment, consists of measurements completed by many people in a doctors sphere of influence. Evaluators completing the forms are usually colleagues, other doctors and members of the multi-professional team. Rarely are patients or families invited to participate. A multisource assessment can be used to provide data on interpersonal skills such as integrity, compassion, responsibility to others and communication; on professional behaviours; and on aspects of patient care and team-working. The data collected are summarised to give feedback.
Raters tend to be more accurate and less lenient when an evaluation is intended to give formative rather than summative assessment (see Box 2
for definitions) (Accreditation Council for Graduate Medical Education & American Board of Medical Specialties, 2000). A body of published work is emerging (Evans et al, 2004; Baker, 2005) that suggests the clear need to differentiate between a tool to be used in developmental appraisal and a method for identifying poor performance. This differentiation is not always apparent. There must also be a note of caution surrounding the assessment of behaviours that are not directly observable. None the less, multisource feedback can make a vital contribution to the measurement and improvement of an individual doctors performance.
There remain two practical challenges. First, construction of tools that all potential assessors can use and second, the compilation of the data into a format that can be reported confidentially to the trainee.
Other assessments
Other assessment tools exist although not strictly for workplace assessments. However, they are worthy of a mention because they have the potential to complement workplace assessments for a complete all-round assessment package.
Written examination
Although workplace assessments cover the trainees performance they are weak at assessing their knowledge in a broad sense. This can be done using multiple choice or similar written papers such as those listed in Box 3
.
| Box 3 Written assessments Multiple choice questions The candidate has to select the correct response to a stem question or statement from a list of one correct and four incorrect answers (other formats can be used) Best of five The candidate has to select the most likely answer out of five options, some of which could be correct but one is more likely than the others Extended matching questions The candidate has to match one out of several possible answers to each of a series of statements

Portfolios
A portfolio is a collection of material, collated by the individual over time, used to demonstrate their chronological learning, performance and development. It can enable individuals to reflect on their abilities and highlight areas that could be improved to enhance the quality of their practice. There are numerous models for portfolio use. In medicine, portfolios tend to be used both formatively (to improve ones own practice) and summatively (for recertification and revalidation). However, there is little evidence to support their use for the latter.
For portfolios to be a valid and reliable assessment tool trainees need to be well prepared in using them and their content must be uniform. Raters should be well trained and experienced (Roberts et al, 2002). Assessment criteria should be consistent with what doctors are expected to learn. The NHS Appraisal Toolkit (http://www.appraisals.nhs.uk) includes a model portfolio for doctors that covers the areas outlined in the GMCs Good Medical Practice (General Medical Council, 2001) and summarised in Box 4
.

(General Medical Council, 2001)

The advantage of establishing a portfolio during postgraduate training is that it is flexible and can therefore accommodate the individuals varying needs as they proceed along chosen career paths and within different specialties.
The record of in-training assessment
The record of in-training assessment (RITA) is a portfolio of assessments that are carried out during medical training. It used throughout UK postgraduate medical training, and is mandatory for specialist registrars and is being introduced for senior house officers. The purpose of this record is to determine whether or not an individual has completed each training period satisfactorily and can proceed with training and ultimately enter the specialist register. The Guide to Specialist Registrar Training (Department of Health, 1998) describes the RITA system, but the generality of its recommendations has resulted in widespread variation between regions and specialties.
A RITA is an assessment record, not an assessment in itself, and it currently relies on in-service assessments that are almost always retrospective and either lack evidence or use unsubstantiated evidence of competence (Postgraduate Medical Education and Training Board, 2005). The clear opportunity now arises to clarify and strengthen a RITA-type system, as new workplace-based assessment processes begin to yield recordable evidence of performance.

Unfortunately, the financial implications of producing robust assessment systems have yet to be calculated. Increasing the level of trainee supervision and assessment will almost certainly result in some reduction in time available for service commitment, although this may be difficult to quantify in advance.
The schedule of assessments selected will be mapped to the foundation years curriculum (Foundation Programme Committee of the Academy of the Medical Royal Colleges, 2005) in a blueprint. The Royal College of Physicians has published a model based on Good Medical Practice and the PMETB Standards for Curricula (2004b) that may serve as an exemplar (Joint Committee on Higher Medical Training, 2003). It will be necessary to establish clear standards for the process and outcome of assessment and then to monitor those standards across programmes. The obvious danger will be that standards will not be equivalent across the UK and abroad.
In a system that relies on assessment by senior colleagues it is likely that very few trainees will be deemed unsatisfactory. There will remain a need for another (national, independent) assessment, perhaps near the end of specialist training. For trainees who continue to perform unsatisfactorily a robust system for career counselling will be required.

By its very nature workplace-based assessment has the advantage of high face validity, although its predictive validity is currently unknown (as is the case for almost all existing postgraduate medical examinations). Many of the specialties for which the assessments were designed have published reliability data, but there is a pressing need for comparable data in the field of psychiatry. Without evidence specific to our specialty, the public and professionals may well lack confidence in decisions based on the workplace-based assessment process.
Workplace-based assessment is an excellent source of information for teaching, educational supervision and feedback, as well as providing evidence of satisfactory (or unsatisfactory) progress and achievement. The system is founded on self-directed learning, so that the trainee schedules each assessment. Trainees will require a good level of organisation and motivation to achieve this. The significant benefit for trainees is the receipt of immediate and constructive feedback.
One of the most likely consequences of the contemporary reforms in postgraduate medical education is an increase in the amount of educational activity in the workplace and this must be properly underpinned if the opportunities offered are to be realised. Each college or specialty must develop a strategy involving workplace-based assessment and examinations of knowledge and clinical skills relating to the entire training period. The tools that we have described here are some of the basic building blocks from which the curriculum and assessment strategy of the future will be constructed.
