Materials and Methods: This is a described-analytic research and a kind of cross sectional and comparative one. For these purpose 40 autistic students with age average 10 years old and 8 months (SD=±2.5) were chosen. Communicative function questionnaire were completed by all subjects‘parents. We used observation check list to examine handedness, footedness, and dominant eye and ear. Using of T-test, covariance analysis data were analyzed.

Results :Data analysis indicated that there is not significant statistically difference  between communicative function and educational state(p<0.05),but participants with weak educational state less tend to definite sidedness preference-in hand and foot not in eye and ear (p>0.05).

Conclusion: These findings reveal that stability of sidedness, which obtains with interventions rehabilitation in autistic students, can perform important role in high language skills and appropriate educational state for them.
