Results are reported for intelligence in Tunisia based on a standardization sample of adults on the Standard Progressive Matrices and in Libya for a standardization sample of 6- to 11- year-olds on the Colored Progressive Matrices. In relation to a British IQ of 100, the mean IQ of the Tunisian sample is 84, and the mean IQ of the Libyan sample is 86.5. In the Libyan sample younger children performed better than older children. There was no difference between girls and boys in either means or variability.
