This study aims to recognize the effectiveness of diagnosing the indicative understanding of the language skills of deaf via sign language from 7-18 years through measuring the mental ability of sign language for deaf. In order to achieve the objectives of study, the items of diagnosing the indicative understanding of the language skills of deaf are converted after conveying significances for validity, reliability and standards in the sample of deaf children into sign language. The sample consisted of 385 children. The statistical data are addressed by extracting Pearson correlation, arithmetic means and standard deviations and (t) test besides using one-way ANOVA test and Scheffe test and least significant difference. Significance about the validity of diagnosing the indicative understanding of the language skills of deaf and conveyed represented in the content validity, structure validity and correlation validity, factorial validity, and concurrent validity. Also, significances about reliability of standard are conveyed and represented in using Cronbach's alpha test, the method of spearman brown. (Published abstract)
