Abstract
The drive towards valid and reliable assessment methods for health professions' training is becoming increasingly focused towards authentic models of workplace performance assessment. This study investigates the validity of such a method, longitudinal evaluation of performance (LEP), which has been implemented in the assessment of postgraduate dental trainees in Scotland. Although it is similar in format to the mini-CEX (mini clinical evaluation exercise) and other tools that use global ratings for assessing performance in the workplace, a number of differences exist in the way in which the LEP has been implemented. These include the use of a reference point for evaluators' judgement that represents the standard expected upon completion of the training, flexibility, a greater range of cases assessed and the use of frequency scores within feedback to identify trainees' progress over time. A range of qualitative and quantitative data were collected and analysed from 2 consecutive cohorts of trainees in Scotland (2002-03 and 2003-04). There is rich evidence supporting the validity, educational impact and feasibility of the LEP. In particular, a great deal of support was given by trainers for the use of a fixed reference point for judgements, despite initial concerns that this might be demotivating to trainees. Trainers were highly positive about this approach and considered it useful in identifying trainees' progress and helping to drive learning. The LEP has been successful in combining a strong formative approach to continuous assessment with the collection of evidence on performance within the workplace that (alongside other tools within an assessment system) can contribute towards a summative decision regarding competence.Keywords
