# Reading gap narrows in 7 Latin American countries on top-student losses

The gap closed between 2022 and 2025 because the most advantaged lost the most points, not because the least advantaged improved; in Colombia the top quartile fell about 16 points and the bottom about 3.

The socioeconomic reading gap narrowed in 7 of 11 Latin American countries with comparable data between 2022 and 2025, the Instituto de Evidencia Educativa reports, and in every case the closing came from heavier losses among the most advantaged students rather than gains among the most disadvantaged. [^2] The seven were Argentina, Chile, Mexico, Paraguay, Peru, Uruguay and Colombia.

The institute's report, 'Lectura en América Latina y el Caribe: bajo desempeño y desigualdades persistentes. Resultados de Pisa 2025,' shows the pattern in Colombia. [^3] Students in the top 25% socioeconomic quartile lost about 16 points on the PISA reading score between 2022 and 2025; students in the bottom quartile lost about 3 points.

The read here is that narrowing a gap by eroding the top is not progress; the bottom barely moved, and the closing came from damage above it.
