Abstract

Data are reported for the Standard Progressive Matrices Plus, applied to a sample of 1641 male and 1441 female school students aged 6 to 18 years old in Cambodia. Scores were higher than those recorded in earlier studies of non-verbal intelligence in Cambodia, indicating an average IQ near 100. There were no consistent gender differences. In addition to age and school grade, numbers of brothers and sisters were associated with test scores. Family income had virtually no relationship with test scores.
