Test Length's Impact on Ability Estimates: Considering Cognitive Fatigue and Speededness

• In Event: GSIC Poster Session I

Abstract

While increasing test length can offer broader content coverage and provide more accurate estimates of students’ proficiency, it may also induce cognitive fatigue and speededness. By using simulation, this study examines the effects of increased test length on proficiency estimates while considering the potential influence of cognitive fatigue and speededness.
