The purpose of this study was to validate the Family Involvement Questionnaire (FIQ) for use in high school settings (9th-12th grade). After the FIQ was redesigned for use in the high school setting, 519 parents completed the questionnaire online. Internal consistency was for the 40-item questionnaire was high (α = 0.93). A confirmatory factor analysis failed to substantiate the FIQ-HS to the elementary version from which it was adapted. However, an exploratory factor analysis yielded three factors consistent with the FIQ-E. Family demographics were compared to participant responses, and significant effects of students’ school and special education status were found.
