Recent literature notes a significant increase in students being diagnosed with Autism Spectrum Disorder (ASD). Yet, no uniform testing protocol exists. It is vital for students and educators that a unified testing process be created and established. This study investigated which ASD testing instruments were currently used in Southern California public schools. Both survey questions and interview questions allowed the participants of this study to indicate which test was their preferred test based on ease of use and accuracy. The study found that the CARS [Childhood Autism Rating Scale] test was the preferred assessment tool. Based on the results of this study, recommendations were made for private schools that do not currently test students thought to have ASD characteristics. It is vital that private schools emulate their public counterparts in the realm of special needs. Thus, the implications of this study can be helpful in establishing a solid testing process that will benefit all parties involved.
