Randomised controlled trial of students access to resources in an examination.

Pass standards based solely on judgements by panellists experienced in closed-resource conditions might not be applicable under open conditions. Questions vary in how much time accessing resources may take and the degree of assistance in selecting the correct answer. A programme of assessment could be constructed to include both closed- and open-resource condition assessments depending on the questions' content and format. Open-resource conditions may promote assessment preparation that focuses more on seeking and evaluating resources rather than learning facts.
