“…Computer Adaptive Testing (CAT) is one of such improvements as the difficulty of the items is adapted to the performance level of the candidate resulting in enhanced accuracy in ability placement. CAT is an assessment improvement that presents items to candidates adaptively based on their ability levels (Thompson, 2011;Rezaie & Golshan, 2015).As such, CAT is regarded as an innovation in educational assessment suitable for Mathematics as a crosscutting subject and relevant to skills sets required for survival in the 21 st century (Hasanah, 2020). Accuracy in ability estimation, together with increased test security, better control of item exposure, better balancing test content areas for all ability levels, makes CAT suitable for standardized testing (Linacre, 2000).Some administrative advantages of CAT are flexible test management and immediate feedback, which may motivate examinees, the use of ability level appropriate items for testing which may reduce test anxiety, flexible testing schedules, and reduced testing time with research showing that CAT can reduce testing time by 50% resulting in cost-saving benefits (Wise & Kingsbury, 2000;Thompson, 2011;Ogunjimiet al, 2021).Also, the pre-evaluation of CAT performance is of relevance.…”
