Diagnostic Assessment

Diagnostic Assessment

TRUE ABA will be starting a pilot program to help decrease wait times for a diagnostic assessment. The pilot program will begin in Arizona and Colorado.


The ADOS-2 is the “gold standard” observational assessment of autism spectrum disorders (ASDs). It can be used to evaluate almost anyone suspected of having ASD—from 1-year-olds with no speech to adults who are verbally fluent. The ADOS-2 is a semistructured, standardized assessment of communication, social interaction, play, and restricted and repetitive behaviors.

Scoring Following the assessment, the BCBA or Qualified Healthcare Practitioner will complete the scoring process. The results are then summarized and sent to your pediatrician for use in a diagnostic determination. The diagnostic determination may result in additional referrals for therapies to address skill deficits.

Diagnostic Assessment


Our assessment team is led by a team of BCBAs and educators who have participated in rigorous training on norm- and criterion-referenced assessments. Each practitioner participates in an ADOS-2 specific training prior to administering the diagnostic assessment along with ongoing training to maintain high-quality standards.


We are excited to offer you this new service! If you are in Arizona or Colorado and would like more information, please contact:
