Existing research identifies several significant, subject-based gender inequalities in education. Male learners have significant advantages in mathematics and female learners have no less significant advantages in reading and writin. Such considerable differences in achievement may have important consequences for the future wellbeing of students. In order to shed light on this phenomenon in Latin America, this report analyzes the gender gaps in educational achievement in the Third Regional Comparative and Explanatory Study (TERCE) led by the Latin American Laboratory for Assessment of the Quality of Education (LLECE).
