The results have been very positive; however, it has been argued that studying subjects in a foreign language may reduce the educational outcomes of students. This paper evaluates this criticism in the Madrid bilingual program adopting a Propensity Score Matching approach, with the PISA 2015 and 2018 data. The model defines a homogenous student subsample from bilingual and nonbilingual schools in terms of the observable characteristics that may jointly influence both the selection of school type and educational scores. Our results, robust to the sample and unobservable hidden bias, indicate that the Madrid bilingual program, in addition to improving students' English level, does not reduce the skills of subjects taught in English or in Spanish. info:eu-repo/grantAgreement/ES/DGA/S23-20R info:eu-repo/grantAgreement/ES/DGA/S23-23R info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 3.1 2024 EDUCATION & EDUCATIONAL RESEARCH 91 / 762 = 0.119 2024 Q1 T1 PSYCHOLOGY, EDUCATIONAL 19 / 74 = 0.257 2024 Q2 T1 1.291 2024 Education 2024 Q1 7.8 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Mancebón, María-Jesús Universidad de Zaragoza (orcid)0000-0002-9111-0461 Mediavilla, Mauro Gómez-Sancho, José-María Universidad de Zaragoza (orcid)0000-0003-3898-8889 4014 225 Universidad de Zaragoza Dpto.
