MATERIALS AND METHODS: This descriptive-correlational study was conducted to determine the knowledge and attitude of 630 high-school students on breastfeeding at a selected public high school in Tehran, Iran in 2018. A researcher-made questionnaire was administered to collect the data, to determine the validity of the tool; content validity was used and to determine its reliability, a test re-test method was applied. Data were analyzed by the nonparametric tests of Chi-square, multiple comparisons, and Spearman correlation coefficient. RESULTS: The results showed that 80.3% had moderate knowledge. The mean score of knowledge in the human sciences group was significantly higher than others. Furthermore, the attitude of 22.5% of girls was positive, 77.5% had no idea, none of them had negative attitudes. There was a statistically significant difference between the mean score of attitude of the students in groups of knowledge (good, moderate, and weak) (P < 0.01), and multiple comparison tests showed that the positive attitude score in the moderate knowledge group was more than the attitude score in weak and good knowledge. CONCLUSION: The results indicate that there is an unbiased attitude about the moderate knowledge of different aspects of breastfeeding among pre university students, although they have a moderate knowledge on a complete and successful breast feeding.
