Result: Theresults of this study indicated that Persian picture receptive vocabulary test is valid and reliable. (CVI=1), test retest reliability=0.81 and split- half reliability =0.91 .This study provided evidence that there is a significant difference (p=0/000) between different age groups scores, and there is no significant difference (p=0.08) in total scores between genders.
