The subjects in this study responded to Edinburgh Questionnaire and the creativity test.
Findings: The results of MANOVA analysis on average creativity scores and its components of students showed that the average of creativity and components of fluency and originality in right handed students are significantly lower than left-handed students, and the average of creativity and components of fluency, originality and flexibility in right-handed students are significantly lower than students who are ambidexterity.
Discussion and creativity and its components in ambidexterity and left-handed students are higher than those of right-handed students, it can be said that the right hemisphere stimulation and interaction in the two hemispheres may affect people's creativity.

The present research is aimed to study the relationship between handedness and academic achievement in secondary students. For this purpose 901 students (441 boys, 460 girls) in 1 to 3 grades of ordinary secondary schools with age average 13 years and 5 months (minimum11 and maximum 20 years) and standard deviation 1 year and 2 months were chosen by cluster sampling method from schools of educational district five of Tehran city. Handedness questionnaire of Chapman and Chapman (1987) were completed by all subjects. Scores of students in written examinations of mathematics, religious education, geography, social science, Persian dictation, experimental sciences, English dictation, history, Arabic and vocational and technical education were gathered for educational achievement criteria. Data analysis revealed that the prevalence of non right-handedness (leftis 16 percent in both sexes. Data analysis by t-test also indicated that academic achievement of right-handers and non-right handers is not significantly different. Although the mean score of non-right handers in history was significantly more than right-handers (α=0.03). So handedness by itself is not related to educational achievement in secondary school students and the parents and the personnel of school need not worry about left or right- handedness in their children.
