Three studies of intelligence in Egypt published between 1957 and 1989 and based on small samples gave British IQs between 77 and 83. The present paper reports the results of a recent study based on a much larger sample in order to examine how far the results of the older studies can be replicated. The Coloured Progressive Matrices was standardized in Egypt in 2011–2013 on a sample of 11,284 children aged 5.6 to 10.5 years. The sample obtained a British IQ of 84.2 and provides a satisfactory replication of the earlier studies.
