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.
