Baecke questionnaire have been widely used to assess physical activity. However, the role of educational level on validity and reliability is still not stablished, being a factor that can potentially influence accuracy self-reported measures. The present study aimed verify for measurement activity in community dwelling adults according education level. sample included 251 (42.4±17.0 years, 55% women). Physical was by objectively measured accelerometer. (EL) classified years into low (<8 years), medium (8–11 years) high (>11 years). A 7-day test-retest analyzed intraclass correlation coefficient. relationship, agreement against accelerometry were Spearman’s correlation, Kappa index, ROC curve, respectively. r = 0.97 (high EL), 0.78 (medium 0.68 (low EL). Sensitivity specificity 77% 71% EL, 54% 80% EL 33% 89% EL. proved be reliable valid habitual with
