The Supports Intensity Scale-Children's version (SIS-C) was developed to provide a standardized measure of support needs of children with intellectual disability. Over half of the norming sample had a secondary diagnosis of autism. Using this subset of the sample, we engaged in exploratory analysis to examine the degree to which latent clusters were present in the data, and after identifying these clusters, the degree to which they mapped on the SIS-C standard scores. A four latent class solution provided the best fit to the data. When mapped on SIS-C standard scores, specific patterns of differences were found in life activity domain scores and overall support needs scores. Implications for future research and practice are discussed.
