Repeated judgements of educational interest

This paper presents three case studies of 60 judgements of interest in a course that was described using the six Holland vocational interest types. Results indicated that the level of personal interest was idiosyncratic and unlikely to be elicited with any certainty until after 30 or more exposures to vocational situations. The explanatory value of the Holland factors varied substantially. This approach offered a diagnostic framework for the detailed assessment of educational-vocational interest.
