This study attempted to examine whether there were differences between high-achieving and low achieving students on self regulation strategies. Three hundred adolescents participated (Mean age = 17.4 years) to measure their own self regulated learning strategies and collected their academic scores from the record office of the schools. The analysis of the data showed that self regulated learning strategies have statistically significant contribution to the students' school performance. The results of the general MANOVA (Multivariate Analysis of Variance) tests showed that the mean differences for those with high and low achiever were statistically significant for the academic self-efficacy (F = 4.349, p < 0.05), self regulation (F = 4.746, p < 0.05), intrinsic value (F = 3.741, p < 0.05),and time management attitude (F = 7.947, p < 0.05) self regulated learning.
