Assessment Practices for Children with Severe Mental Retardation

Potential limitations in assessment practices with children who have severe mental retardation have been identified in the literature. The purpose of the study was to investigate the extent to which practicing school psychologists use alternative methods as opposed to standardized/norm-referenced measures in the assessment of children suspected or identified as having moderate to severe/profound mental retardation. As part of a larger survey, assessment practices of school psychologists with children functioning in the more severe level of mental retardation were reported by 202 school psychologists. Results suggest that school psychologists use norm-referenced measures at all grade/age levels. Various other types of methods were also noted by 0.5 to 35.8% of the respondents, with the highest frequency of alternative approaches employed at the preschool level. Implications for assessment practices with children with moderate to severe/profound mental retardation and for the training of school psychologists in alternative methods of evaluation consistent with the need to link assessment to intervention are discussed.
