This study aimed to examine the impact of omega-3 fatty acid and vitamin E on school achievement and cognitive abilities among fourth class students. The sample of the study consisted of 96students(53 males and 43 females) with low school achievement from fourth class, in UNRWA Schools, and governmental schoolsfrom Rafah province who completed the course of omega-3 and vitamin E for 16 weeks. For data collection, the researcher used school records, cognitive abilities test, and anthropometric measures. Data were collected twice,at baseline and after 16 weeks of receiving the supplement. The results showed that 47.9%of children were from UNRWA schools and 52.1% from governmental schools, 21.9% were studying less than one hour at home, and 68.8% studying for 1 – 2 hours, 64.6% watch TV for 1 – 2 hours, and 20.8% watch TV more than 2 hours, 14.6% sleep less than 8 hours, and 79.2% sleep between 8 – 10 hours, 13.5% had breast feeding for 3 months and less, 27.1%had breast feeding for 4 – 9 months, 39.6%had breast feeding for 10 – 15 months, and 19.8%had breast feeding for 16 – 24 months.The mean body weight of the children was 28.187 kg, mean height was 1.29 m, the mean BMI was 16.759.
