This study examined the performance of English learners (ELs) taking the ACT® test with testing supports, as compared to ELs and non-ELs taking the ACT without supports or accommodations. Contextual factors were also explored, including high school experiences and demographic characteristics such as low-income and first-generation college student status that may be associated with their scores. Results indicate that ELs tended to score substantially lower than non-ELs, and ELs who tested with supports tended to score lower than ELs who tested without supports. ELs in both groups, particularly those testing with supports, tended to take fewer core academic courses, fewer honors or AP courses, and had lower high school grades than non-ELs. ELs in both groups, particularly those testing with supports, were also more likely to be non-White, low income, and/or first-generation college students. Regression analyses found that demographic and contextual factors, along with limited English proficiency, played a substantial role in predicting the performance of ELs taking the ACT, both those testing with and without supports. It is important that ELs are provided with a rigorous education that includes instruction in both English language and core academic content to ensure that they have equitable opportunities and experiences as compared to their English proficient peers.
