Screening Tool For Autism in Two-Year-Olds (STAT™)

The Screening Tool for Autism in Two-Year-Olds (STAT™; Stone, Coonrod, & Ousley, 2000) is an instrument for screening for autism in children between the ages of 24 and 36 months.


This instrument consists of 12 interactive activities administered within the context of play. Behaviors are examined in four social-communicative domains: play, motor imitation, and requesting and directing attention. The observations are assessed, and performance on each item is rated as Pass, Fail, or Refuse, based on specified criteria. The STAT™ may be given by a wide range of professionals, but training in administration and scoring is required. Administration time is approximately 20 minutes.
