Score Comparability for Language Minority Students on the Content Assessments Used by Two States
We examined three indicators of score comparability (reliability, internal test structure, and differential item functioning) for fourth and eighth grade ELL and former ELL students who took the NCLB-mandated content assessments in English-language arts and mathematics. The results from this study showed that although the assessments from the two states differed somewhat with respect to the three indicators, a high degree of score comparability was found for both states’ content assessments.
