Abstract

Results are reported for intelligence of 6 to 11 year olds in Libya on the Coloured Progressive Matrices assessed in 2006 and 2017. Increases of CPM mean raw scores translate into a gain of 2.8 IQ points over the 11 years, or 0.25 points a year. Gains were seen mainly at the older ages, suggesting that they are caused by improvements in the educational system rather than by factors acting on preschool children. There was no difference between the IQs of girls and boys.
