This study provides a framework for the evaluation of assessments that may be used in adult continuing education. It provides an example of the analysis of an examination for 33 solicitors seeking specialist accreditation. Resampling was used to generate a group of 1000 results, and responses were analysed using a Rasch model. Results indicated a select and capable group of candidates for whom many items in the assessment were redundant. A five-step general model for evaluating formal assessments in adult education is outlined. (Contains 7 figures.)
