Abstract
This study was conducted to make an empirical comparison of differential item functioning (DIF) detection for polytomously scored items using Standardized Mean Difference (SMD) and Logistic Regression with residual analysis. The two methods were compared using eighth grade and twelfth grade students’ performance on five prompts from the 2007 NAEP writing assessment. The two methods were employed to detect whether each prompt functioned differently on the performance of native English speakers and English as a second language (ESL) students. Results suggested that SMD and logistic regression with residual analysis tend to agree on the detection of DIF in polytomously scored items.
