The test has four subtests, which require students to make inferences, interpret photographed scenes, and explain how they would resolve problems with peers. The Examiner’s Manual includes a comprehensive discussion of the test’s theoretical and research-based foundation, item development, standardization, administration and scoring procedures, norms tables, and guidelines for using and interpreting the test’s results. Reliability and validity studies were conducted out with individuals with normal language abilities and individuals who had previously been diagnosed with autism spectrum disorder. The average coefficient alpha ranges between .77 and .92 for the subtests and is .94 for the Social Language Development Index. Studies were conducted to examine the ability of the test to differentiate students who are autistic from those who are not. The results demonstrate that a Social Language Development Index cutoff score of 90 resulted in a sensitivity of .82, a specificity of .86, and a receiver operating characteristic/area under the curve of .91.
