Two special classrooms were provided for 20 students at the preschool and kindergarten level who had severe hearing impairments. Two teachers and two instructional aides condcted classroom activities centered around sense training (visual, tactile, and auditory experiences). Speech development and communication skills were desired outcomes. To measure student gains in eight subtest areas, the Nebraska TEST OF Learning Aptitude was administered. In one year, the preschool students made an average growth of one year and 11 months in mean learning age. The kindergarten group showed an average gain of one year and five months in mean learning age. Student records, samples of classwork, and teacher written reports on each student (including sense training, socialization, responsibility, basic learning skills, and language development) correlated with the test data.
