Background and Aim: The standard tests are tools for quantifying different aspects of speech & language abilities and communicative skills. However developing and applying standard tests is necessary for assessing, screening, defining the speech & language abilities, diagnosing the speech & language disorders and attending to outcomes of treatment process. Therefore in this study for providing general view of speech & language assessment tests, we reviewed some of tests related to some important aspects of speech & language abilities.
Method: This research is a review study based on American speech-language and hearing association. We reviewed exactly the tests that are in this association site because it is one of comprehensive and reliable references for speech-language pathologists. Just four most practical aspects of them, from the first test developed to now (2010), are selected and then analyzed.
Results: In this study, 251 tests of assessment of speech and language are reviewed. 54 tests are related to articulation and phonological assessment. One hundred and forty tests are related to assessment of children expressive language. Forty three tests are available for assessing the expressive language in adult. 14 tests are presented for evaluating autistic children.
Conclusion: However there are widespread spectrum of standard tests but it is necessary to develop other tests in different aspects of speech and language pathology.

Background and Aim: Semantic test "Pyramid and Palm Trees"(PPT) Test was used for assessing cognition and semantic system in brain disorders, semantic dementia, Alzheimer disease and aphasia. This test was designed in 1992 by Howard and Patterson and includes both versions picture and word. It has validity and reliability. The aim of this study is to determine of validity and reliability of Persian picture version "Pyramids and Palm Trees" Test and compare with aphasia and normal adults.

Materials and Methods: In this cross - sectional study, 45 subjects included 15 Aphasia and 30 normal adults respectively the mean age and standard deviation of 53 (7.77), 53 (7.91) years participated. All of participants were matched in the age and sex, and education and bilingualism. In the first stage, the picture version PPT had given to 14 expert(11 Speech and language pathologists, 3 Linguists) in order to determine content and face validity. According to their comments, pictures that were very far from Persian culture were replaced with proportional pictures with Persian culture. Then the reliability was calculated by performance of PPT during an interval of 5-7 days in two stages for all of aphasia patients. In order to compare of results, PPT was performed on normal adults. Then, the results were analyzed by SPSS18 software. The statistic tests were included of lavashh correlation for validity, Intra-class correlation coefficients (ICC) for reliability and independent T-Test for comparison of scores mean of picture version PPT between aphasia and normal adults.

Results: ICC ranges for reliability were 0.88 – 0.93. Also difference of scores mean of picture version PPT between aphasia and normal adults were significant (p<0.05).

Conclusion: The Persian version PPT have validity and reliability. This study showed semantic disorder in aphasia patients in compared with normal adults.
