This investigation is an initial examination of possible enhancement of executive function through a dual-language (50:50) education model. The ethnically diverse, low-income sample of 120 children from Grades K, 2, and 4 consisted of approximately equal numbers of children enrolled in dual-language and traditional classrooms. Dual-language students in Grades 2 and 4 performed better on a measure from the Trail Making Task requiring inhibition and rule-switching. The results indicate that the established benefits of bilingual exposure can be generalized across SES and ethnicity and can be acquired within the context of elementary school programs.
