Research projects

This research project aims to generate timely evidence to better understand one of the mostrelevant social challenges: the improvement of educational equity. Specifically, it is intended to develop a composite indicator that allows to reflect the level of equity of educational systems based on a single criterion, without losing its multidimensional nature and considering the different priorities and heterogeneities of educational systems. This synthetic indicator will make it possible to provide a global and fair comparison of the performance, in terms of educational equity, of the different OECD countries (and regions) that have participated in the latest editions of the most relevant international large-scale assessments (PISA, TIMSS and PIRLS).

To achieve this purpose, we carried out an exhaustive review of the theoretical and empirical literature of the different dimensions of equity, selecting the most appropriate individual indicators for the empirical analyses. The first preliminary results for the case of the Spanish regions using the PISA 2018 database corroborate two key facts: (i) there are notable differences in terms of educational equity between educational systems, (ii) the results differ substantively and qualitatively depending to the dimension and the indicator used. Currently, we are working on the development of a methodology for their aggregation, based on the conditional extension of the "Benefit of the Doubt" (BoD) model, to adapt it to the priorities and heterogeneous characteristics of the different OECD countries that participated in the latest wave of the PISA report. Preliminary results are expected in the next quarter, which will be presented at the next international conferences and will lead to the elaborations of the first scientific paper.
