First Regional Comparative and Explanatory Study (PERCE)

Implemented in 1997 - Download PERCE database

This study, implemented by the Latin American Laboratory for Assessment of the Quality of Education (LLECE) in 1997, obtained the first comparable data on learning achievement in the areas addressed among schoolchildren in Latin America and the Caribbean. This joint effort reflected one of the continent’s most significant political achievements in the field of education, with the creation of an agreement between 13 countries.

Coming together in a spirit of motivation to improve quality and equity in education, they leveraged their national measurement and assessment systems and, with coordination from the UNESCO Regional Bureau of Education for Latin America and the Caribbean, between June and November 1997 the countries applied language and mathematics tests and questionnaires on associated variables affecting samples of third and fourth grade children, parents, teachers, and school principals.

The value of the study was heightened by its providing not only data on children’s learning achievements and performance levels, but also information on factors associated with these results. This information was used to inform governments of their students’ comparative and absolute learning achievement levels, and to provide policy makers with material to feed into decision making processes relating to education policies.

The results were contained in three main reports:

First Report of the First International Comparative Study on Language and Mathematics, and Associated Factors, among Third and Fourth Grade Students (1998)
This report gained a first insight into the region’s education quality and equity situation, based on learning achievements in language and mathematics among third and fourth grade students. The results showed that at the close of the 20th century, most participating countries’ students’ learning achievements were significantly below the regional median level, with three countries scoring on the median and only one significantly above it, two standard deviations beyond the regional average.

Second Report of the First International Comparative Study on Language and Mathematics, and Associated Factors, among Third and Fourth Grade Students (1998)
This report provides additional and complementary information, with the results of analyses of the factors that explain the children’s results. These factors were investigated in terms of variables linked to the children themselves, their parents, teachers, and school principals, from data collected with associated factor questionnaires applied alongside the tests. The report includes explanations of the results and information aspects of teachers, classrooms, and schools that could allow the current education situation to be improved upon.

Technical Report on the First International Comparative Study on Language and Mathematics, and Associated Factors, among Third and Fourth Grade Students
(Spanish version)
This document contains the information previously published in the first and second reports, enhanced with results broken down by country and including the groundings of the sampling procedures, data collection, and analysis disaggregated by country and social stratum, for both learning achievement and associated factor data. In the latter case, it is of particular relevance that the information contained in this report allows each country to recognize its own characteristics in some of the variables investigated, and the document allows readers to gain an in-depth understanding of study possibilities arising from the analysis of levels of learning achievement, as well as a linear hierarchy.
