The Social Language Development Test Adolescent: Normative Update (SLDT-A: NU) assesses language-based social skills. Specifically, it measures students’ ability to make inferences, and interpret and respond to social interaction. Performance on the test differentiates typically developing students from those with autism spectrum disorder.

Description of the Test
The test has five subtests (Making Inferences, Interpreting Social Language, Problem Solving, Social Interpretation, and Interpreting Ironic Statements) that yield scaled scores. A composite score, called the Social Language Development Index, represents overall performance on the subtests. The Examiner’s Manual discusses the test’s theoretical and research-based foundation, item development, standardization, administration and scoring procedures, normative tables, and guidelines for using and interpreting the test’s results. Reliability and validity studies were conducted with students with typical language abilities and students who had previously been diagnosed with autism spectrum disorder.
The average coefficient alpha ranges between .76 and .86 for the subtests and is .95 for the composite. New validity studies demonstrate the test’s ability to differentiate students with autism spectrum disorder from typically developing students. The results demonstrate that a Social Language Development Index cutoff score of 90 resulted in a sensitivity of .71, a specificity of .96, and a ROC/AUC of .90.
