Abstract:Item difficulty and item discrimination are indicators of the evidence strength of items in an assessment. Methods of determining these indicators leave room for improvement. Identifying task features of assessment items that influence these indicators could create a systematic and accurate method for quality assurance, reduce pre-testing expenses and improve assessment quality. This study attempts to find such task features within the 2F reading comprehension items (N = 128 items) that form the basis of the Dutch central exams for intermediate vocational education (MBO). This study will focus specifically on task features related to the information within the text that is necessary to respond to the items, among which are the propositional complexity, abstractness and the necessity to draw inferences. These task features are identified and coded through the use of concept mapping. The selected task features are analysed in regard to the extent to which they correlate with- and can predict variation in both item difficulty (p-value) and discrimination (Rir). These values are provided by Cito and are derived from test administration data collected between 2010 and 2018. Multiple information features were found that correlate with item difficulty and discrimination.
