Students' academic achievement is one of main indicators in evaluating higher agricultural education. One of the most effective strategies in terms of academic achievement is to reinforce self-directness and meta-cognitive skills. The main objective of this study was to evaluate the effects of elf-directness and meta-cognitive skills on the academic achievement of agriculture students in Iran. This research was a descriptive-correlational study using a survey technique. The instrument adopted in this study was a questionnaire which validity was confirmed by a group of curriculum developers and educational planning specialists in the higher agricultural education system. Cronbach's alpha coefficients were used to determine the reliability of this scale. Cronbach's alpha values ​​for different variables showed the acceptable reliability of this instrument (0.74≤α≤0.96). The statistical population of the study consisted of the agriculture students in Iran (N=236973). The sample size was estimated to be 150 persons by using Cochran statistics and two-stage sampling method (cluster sampling and proportional stratified random sampling). The results showed that the variables self-directness, metacognitive skills, and social conditions had a positive and significant effect on the academic achievement among these students.
