The importance of understanding the pathology, nature, and treatment of Autism Spectrum Disorders (ASD) has always been emphasised throughout school. Children with ASD have difficulties in verbal and non-verbal social communication, which limit their ability regarding effective social communication and academic achievement. The purpose of this research was to compare learning strategies and executive functions among successful and non-successful autistic students in terms of academic achievement. For this purpose, 15 successful students with ASD and 15 non-successful students with ASD were recruited via the purposeful sampling method. The Autism-Spectrum Quotient Test, the executive functions and learning strategies questionnaires were used. Data was analysed with an independent t-test. Results showed that, successful students with ASD had a significant difference with the second group in all variables of learning strategies in addition to inhibition, emotional management, planning, organizing and attention shifting. It can be concluded that students with ASD who are successful in education use more learning strategies and have better executive functions compared with autistic students who are not successful in education.
