- CARS (Childhood Autism Rating Scale): a 15 item rating scale that distinguishes mild-moderate-severe autistic symptoms
- M-CHAT (Modified Checklist for Autism in Toddlers): examines possible symptomology correlating with autism
- Vineland-II Adaptive Behavior Scales: examines domains of communication, daily living skills, socialization, motor skills and maladaptive behavior
- ABLLS (Assessment of Basic Language and Learning Skills): examines basic learner skills, academic skills, self-help skills and motor skills
