Revised manual for the Grover-Counter Scale of cognitive development (GCS)

Psychological assessment tools are often used to obtain information about a learner's cognitive ability, interest, aptitude and personal characteristics. The major aim in devising the Grover Scale was to provide an instrument which could reveal such cognitive functioning in persons with extremely impaired verbal skills, whether receptive or expressive or both. The Scale was designed for use with the following South African populations: in general, normal children in the chronological age range from 3 years to approximately 10 years, specifically, mentally handicapped children and adults from chronological age 5 years onwards. The test is not intended to replace a recognized and well-standardized predominantly verbal type test for use with subjects who have well developed verbal skills. Neither is it intended as an all-round development scale, though in both cases it can serve as a valuable supplement.
