Teacher attitudes toward inclusion of English Learners (ELs) in the mainstream classroom have primarily focused on explicit beliefs as accessed through observation, case studies, and self-report surveys. The authors explore implicit mainstream teacher beliefs about ELs using the newly created Implicit Association Test-EL, with correlations to explicit beliefs being made using the English-as-a-Second-Language (ESL) Students in Mainstream Classrooms: A Survey of Teachers' Explicit Beliefs survey. Findings from the IAT-EL indicate a slightly negative implicit belief about ELs from 197 respondents. Implicit and explicit beliefs about ELs were not significantly correlated, which is in keeping with current Implicit Associate Test (IAT) literature.
