glossary, read aloud
Grade 8 and 9 students from urban and suburban school districts in two U.S. states
For English language learner (ELL) students engaging in a math assessment, the use of a glossary accommodation did not significantly impact their performance on the assessment. Furthermore, the use of a read-aloud accommodation provided mixed results with the ELL students, showing no significant effect for state X and a significant positive effect for state Y. State Y's testing policy had a more systematic approach with the implementation of the read-aloud accommodation compared with state X. Additionally, state Y students had likely received the read-aloud accommodation before in a systematic way, unlike state X.
