Results are given for three studies of samples tested with the Standard Progressive Matrices (SPM) in Morocco. The first consisted of 85 children (boys, girls; M age = 8.5 yr.) in the town of Kenitra and obtained a British IQ of 74. The second consisted of 202 adults (92 men, 110 women; M age = 26 yr.) in four cities and obtained a British IQ of 81. The third consisted of 1,177 secondary school children (723 boys, 454 girls; ages 12-17 yr.) in a rural area and obtained a British IQ of 73.3. It is proposed that the best estimate of the Moroccan IQ can be obtained as the average of the three results, giving an IQ of 76.
