The goal was to verify the effect of school performance on fluid intelligence and vice versa after controlling the socioeconomic variables. Students (N = 3724) between the ages of 14 and 15 years (51% females) that were enrolled in 66 schools from different socioeconomic levels, participated in this study. The Raven Standard Progressive Matrices test (SPM, fluid intelligence measure), the 2003 PISA test (school performance measure) and a short socioeconomic questionnaire were administered. Diverse multilevel analyses were conducted. The results were: 1) a positive relationship between PISA and SPM, although a stronger correlation was observed as aggregated (r = .89), rather than individual scores (r = .58) were used; 2) after controlling social variables, the PISA scores could vary up to 7.79 times due to variation in SPM scores; 3) after controlling social variables, the SPM scores could vary up to 1.4 due to variation in PISA scores; 4) the socioeconomic status of schools exerted a greater influence on PISA scores than on SPM scores; and 5) there was a variability among schools regarding school performance (35.2%) and intelligence (6.3%) which was not explained by the covariates and random effects. The impact of these results for education policies is discussed. © 2015 Elsevier Inc. All rights reserved. Keywords: Intelligence School performance SES Latin America 1. Introduction 1.1.
