Background and Aim: Evaluation of hearing-impaired children's auditory skills by a valid test is very important before starting auditory training. There are many different tests available for languages other than Persian, and some limited Persian tests for children above 5 year of age as well. Accordingly considering the importance of early intervention, we aimed to design a test for evaluating auditory skills of 3-4 year-old hearing-impaired Persian (Farsi) children, which is not available to date.Methods: The study method was test (scale) construction. The test named Tavana includes four subtests: detection, discrimination, identification and sentence comprehension. For determining content validity of the test, the vocabulary of 3-4 year-old normal-hearing and hearing-impaired children and also the comments of seven specialists were applied. We classified 10,10,8 and 6 sub skills for 1st to 4th subtests, respectively.Results: The content validity of Tavana test's subskills were 100%, 83%, 96% and 95%, respectively (mean=94%). Mean time for test performance was 82 minutes.Conclusion: Content validity of Tavana test was 94% which was statistically valid compared to Modarres test (97%) and Mazaheryazdi test (88%).
