Data were collected for 1,877 candidates in the 1985/1986 base year from a sample of 38 schools--7 boys' single-sex, 9 girls' single-sex, and 22 co-educational schools. Findings showed that, at the Advanced Level, girls in the single-sex setting outperformed their counterparts attending co-educational schools, in the sciences. The performance of boys in the co-educational schools was significantly improved over their performance at the Ordinary LevelSingle-sex schools
