Sex differences on the Standard Progressive Matrices and in educational attainment in Kuwait

The Standard Progressive Matrices was standardised on a sample of 6529 8–15-year olds in Kuwait. There was a small sex difference of .08d (1.2 IQ points) favouring girls. Educational tests of verbal comprehension, foreign language ability and mathematics were given to a sample of 15-year olds. On these also, girls obtained higher mean scores. These results fail to support the theory that in traditionalist countries females have lower IQs and educational attainments than males.
