Boys vs Girls Performance
Girls now outperform boys in reading by an average of 25 points on PISA across the OECD. Boys retain a small advantage in mathematics (closing). Girls outnumber boys in tertiary enrollment in most OECD countries by 1.2-1.4×. The historical educational gender gap has reversed — and the consequences are reshaping labor markets and family formation patterns.
Key insights
The reading gap is large and consistent
Girls outperform boys in reading in every OECD country, every age group, and every PISA cycle. The gap of ~25 PISA points represents roughly 1 grade level. Possible causes: girls develop reading skills earlier; school reading material favors girls' interests; teacher attitudes; behavioral differences in attention. The gap has been stable for 20 years — none of the explanations have produced policy interventions that close it.
The math gap has closed
Boys' historical math advantage has shrunk to ~5 PISA points and is statistically insignificant in many countries. Iceland, Sweden, Finland, Norway, Latvia, Jordan have girls ahead in math. The narrowing reflects educational reform, changing female expectations, and reduced gender stereotyping in math instruction. The gap remains larger in tertiary STEM majors and STEM careers — pipeline rather than aptitude effects.
Tertiary reversal has consequences
Female share of tertiary enrollment in OECD: 57% (women earn 57% of bachelor's degrees). The pattern is now established for two decades. Effects on labor markets: women dominate teaching, nursing, social work, communications; men dominate trades, engineering, technical fields. Effects on family formation: in countries with tertiary gender gap, marriage rates have fallen — educated women face shortage of similarly-educated men.

Points (positive = girls ahead)
Key Finding: Girls outperform boys in reading in every country tested.
Female share of tertiary enrollment — selected OECD
% of tertiary students who are women
Key Finding: Women are majority in nearly all OECD countries; only Korea, Japan, Switzerland have male majorities.
Methodology & caveats
Why boys fall behind
Multiple hypotheses: behavioral differences (boys' fidgeting/attention disadvantages in modern classrooms), feminization of teaching (most primary teachers are women, possibly biased grading), curriculum content (reading materials weighted toward girls' interests), peer culture (academic achievement less socially valued among boys), labor-market signals (trades and tech still pay men well without college). Each explanation has empirical support; weights vary.
Why gap has plateaued
After widening through 2000-2010, the gender education gap has been roughly stable since 2015. Policy interventions (boys' literacy programs, male teacher recruitment) have produced modest effects. The structural pattern appears to be settling — though concern about boys' educational performance has risen in many advanced economies.
Labor-market translation
Despite educational outperformance, women still earn less than men on average (gender pay gap). Reasons: career choices, motherhood penalty, persistent occupational segregation. Educational advantage hasn't fully translated to labor-market parity — but it does mean future female cohorts are entering labor markets with substantial human-capital advantages over their male peers.
