Normative data on the Koppitz developmental scoring system for the Bender-Gestalt test were derived from a sample which included 510 protocols of adult resident retardates. Percentile norms are presented on Koppitz error scores for three AAMD ranges of retardation based on WAIS IQs and two AAMD ranges of retardation based on Stanford-Binet IQs.
