One aspect of spoken language skills is vocabulary, which provides a basis for acquiring other language aspects. Assessing a child's vocabulary knowledge aids in identifying the child's language strengths and weaknesses and predicts reading ability and academic success. Speech-language pathologists frequently employ various procedures in clinical and research settings to assess the children's language skills and help make decisions about diagnosis, eligibility for services, and intervention.


This systematic review investigated currently available vocabulary tests developed or adapted for Iranian Persian-speaking children.

Data Sources: 

Based on the PRISMA guideline, electronic searches of three national (SID, Irandoc, and Magiran) and four international (ScienceDirect, ProQuest, PubMed, and Google scholar) databases were carried out from 2000 to 2022 to identify Persian vocabulary assessment tools. Study Selection: Search in the reference lists of papers, unpublished theses, and content of related journals also supplemented the database searches. Data Extraction: The psychometric properties of these tests were reviewed based on specific criteria used in the literature. The papers and test manuals were examined according to these criteria.


Eight tools have been developed or adapted for assessing vocabulary knowledge in Iranian Persian-speaking children. Reviewing the content and psychometric properties of the included tools indicated that the Test of Language Development- Primary:3 (TOLD-P:3) is the only accessible published tool with the most reported psychometric evidence. It measures language development in children; however, it is a multi-modal test that includes vocabulary subtests.


This review revealed that most of the reviewed tools were in the primitive stages of test development or adaptation procedures and did not examine many psychometric properties. As a result, vocabulary is a field that requires more attention because there is no accessible, standardized tool with adequate psychometric properties.
