Data collection was accomplished by observation, completion of questionnaires, and speech recording.   Results: There was a significant difference in language development in 11 sub-tests and five lingual gains on the Persian TOLD-P3 test between early (3-6 months of age) and late identified/intervened (12-15 months of age) hearing-impaired children (P
