High speed high stakes scoring rule: assessing the performance of a new scoring rule for digital asssesment

In this paper we will present the results of a three year subsidized research project investigating the performance of a new scoring rule for digital assessment. The scoring rule incorporates response time and accuracy in an adaptive environment. The project aimed to assess the validity and reliability of the ability estimations generated with the new scoring rule. It was also assessed whether the scoring rule was vulnerable for individual differences. Results show a strong validity and reliability in several studies within different domains: e.g. math, statistics and chess. We found no individual differences in the performance of the HSHS scoring rule for risk taking behavior and performance anxiety, nor did we find any performance differences for gender.
