Background and Aim: Verb is one of the most important aspects of a sentence, and verb deficit is a noticeable part of developmental language disorders. In Iran, there is no standard test for evaluating this aspect of language in children. This study aimed to develop and evaluate a picture verb test for 36-54 month-old normal Persian-speaking children, and assess its ability to differentiate between children.
Methods: A list of verbs that could be depicted was collected and content validity was assessed by seven speech therapist. 55 verbs were selected. Then, three pictures were prepared for each verb and one of those pictures was chosen by the same seven specialists. 106 children aged 36-54 months participated in this study. They were divided into three groups (36-42, 42-48, and 48-54 months). Reliability of this test was assessed by Spearman&aposs correlation and internal consistency. Correlation between children&aposs scores and their age was calculated.
Results: Content validity index of all verbs were 1. Spearman&aposs correlation of 0.89 and internal consistency of 0.60 was obtained. By deletion of item method, the Kuder-Richardson score was enhanced to 0.71. There was a significant correlation between children&aposs ability to respond and their age (r=0.76, p < 0.001).
Conclusion: This test is a suitable tool for assessment of verbs in 36-54 month-old Persian-speaking children and can differentiate between three groups under study.

Background and Aim: Phonological awareness (consisting of phoneme, syllable and intra-syllable awareness) is an important part of receptive and expressive language it facilitates reading and writing skills through phonological re-coding. Multiple studies in several languages have studied the relationship between phonological awareness and dictation. This research is based on a study of the relationship between phonological skill and spelling score in first-grade Persian students.

Methods: Four hundred first-grade students participated in the study, including 209 girls and 191 boys. A phonological awareness test was individually administered for each student and then a spelling exam was administered in groups. The correlation between the two tests was studied using a simple regression model. The comparison of mean scores of girls and boys was evaluated employing an independent t-test.

Results: A correlation coefficient of 0.82 was obtained between phonological awareness and spelling proficiency (p<0.001). Phonological skill sub-tests also showed a significant correlation with spelling proficiency (highest for phoneme awareness r=0.34 and lowest for rhyme awareness r=0.12). The mean scores of girls and boys differed significantly (p<0.05).

Conclusion: There is a strong positive association between phonological awareness and spelling proficiency. Therefore, if phonological skill is improved, spelling score can be enhanced.
