Abstract
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.
