Attempts were made to develop a test battery for screenings of speech and voice disorders among school children and to apply it to school children in Itabashi-ku, Tokyo. The test battery consisted of three tests for detecting articulation disorders and adiadockokinesis of articulators as well as four check items for detecting hearing probles, retarded development of language, voice disorders, fluency disorders and other speech disorders due to neurological problems.2, 011 children (group 1) were tested by twelve school doctors (otolaryngologists) at the physical examination prior to entering school, and 1, 698 school children in the first grade (group 2) were tested by ten otolaryngologists at the regular physical examination. Sigmatismus and Zetazismus were found in 5.3% of children if the group 1 and in 8.1% of children of the group 2. Adiadockokinesis of articulators were observed in 6.2% of children of the group 1 and 6.5% of children of the group 2. Voice disorders and stuttering were found in 1.0% and 0.6% of children of the group 1, and in 2.2% and 0.6% of children of the group 2, respectively. It took 40 to 50 seconds per child, and it was thought that this was somewhat long for the examiners.Through these experiences the following conclusions were directed:1) The results are influenced by examiner's auditor acuity as well as knowledges of speech and voice disorders.2) Our test battery must be more simplified for a practical use.
