The aim of the research was to ascertain whether a framework of cognitive demands, known as CRAS, is a suitable tool for comparing the demands of vocational qualifications. CRAS was developed for use with academic examinations and may not tap into the variety of demands which vocational qualifications place on candidates. Data were taken from a series of comparability studies by awarding bodies and the national regulator. The data were the frameworks (often questionnaires) used to compare qualifications in these studies. All frameworks were mapped to CRAS. It was found that most aspects of the various frameworks mapped to an aspect of CRAS. However, there were demands which did not map to CRAS; these were mostly affective and interpersonal demands, such as working in a team. Affective and interpersonal domains are significant in vocational qualifications; therefore, using only CRAS to compare vocational qualifications is likely to omit key demands from the comparison.
