Although autism Spectrum Disorders (ASD) have been considered to be associated with intellectual disability, there is no known study on cognitive capacities of primary school aged children with ASD in Nigeria. The objective of this study is to compare the intelligence quotient (IQ) of primary school pupils with autism spectrum disorders with that of their controls in Uyo, Nigeria. Gilliam Autism Rating Scale–second Edition (GARS-2) and Gilliam Asperger Disorder Scale (GADS) were used to identify school children with Autism Spectrum Disorders (ASD). Their intelligence quotient was assessed using the Draw–A–Person–Test (DAPT). The findings were compared with that of their age, social class and gender matched controls. A total of 29 pupils with autism spectrum disorders were identified out of 2,641 studied. Twenty-six out of the 29 children with ASD were suitable for intelligence quotient estimation using DAPT; two of the pupils were less than 4 years of age and one had features suggestive of Down syndrome. Eleven out of 26 pupils (42%) assessed for intelligence quotient had intellectual disability (IQ<75%) while fifteen (58%) had normal intelligence (IQ>75%). The overall mean IQ score of the pupils with ASD of 82.5±22.5 was significantly lower than that of the controls of 108.9±14.8 (p<0.01). Pupils with Asperger’s disorder had the highest mean IQ while those with autistic disorder had the least mean IQ with a statistically significant difference (p<0.01). ASD are associated with low IQ among school children in Uyo, Nigeria.
