Language disorder is found in 5—10% of children. Etiologies of delayed language are mental retardation, Hearing loss, developmental dysphasia, dysarthria, infantile autism, psychological prob- lem and others. Delayed development of language is a key symptom of these diseases and oftentime the chief complamt which brings the child to the physician. Pediatrician is in the position to diagnose not only delayed language but the causativ diseases also. The development of language was studied in children from brith to 3 years of age and early language screening test was developed on the basis of the study result. Language of 433 healthy children from 16 days to 1170 days of age were evaluated on the pretested 44 items and 25, 50, 75 and 90th percentiles of test items were calcalated. These data were transferred to screening tests, consisted of 44 bars according to chronological ages. The results were compared with reports of other countries. There was some differences in “cooing” tests but generally the results were comparable. Even though the specificity and the validity of the test are not yet confirmed, this language scale can be used as language screening in 0—3 year children.
