In order to determine the extent of deficiencies found in deaf children with learning disabilities so that appropriate remedial curriculum could be developed, a series of diagnostic tests designed to differentiate deaf children with learning disabilities from typical deaf children was constructed and evaluated. The tests developed were said to meet objectives of both the classroom teacher and the developmental psychologist. A test battery was devised for the 3 to 8-year-old range with modification in the selection procedure of the tests to account for developmental change. The CREED 3 test battery measured gross motor coordination, sensory motor behavior, visual analysis, attention and memory, and conceptualization. The population tested included 444 3 to 4-year-olds, 227 5 to 8-year-olds, and 289 7 to 8-year-olds, all of whom were deaf children in the New York State schools for the deaf. Results showed that the test battery differentiated successfully among those deaf children with and without learning disabilities. Significant differences in performance on subtests in all five areas were found for each of the three age groups. Evidence also suggested that the test battery described differences within the typical and special groups as a function of age. (For related documents, see also EC 041 647, EC 041 649-50.) (CB)
