Prepared by two committees of the American Organization for Education of the Hearing Impaired, the pamphlet provides a guide for formulating standards of professional training for teachers of hearing impaired children. Competencies needed by teachers of the deaf are defined in the areas of communication (speech, hearing, language, lipreading, visual perception), curricular adaptation, psychological tests and measurements, social adjustments, home-school relations, and philosophy of education. For teachers of the hard of hearing, competencies explained include personal characteristics of the teacher, knowledge of auditory comprehension, speechreading, speech, language development, other special knowledge, and essential abilities. Seven recent publications on the preparation of teachers of the hearing impaired are cited. (JB)
