Abstract: Autism spectrum disorder （ASD） is a chronic，lifelong neurodevelopmental disorder.Most cases occur in early childhood.With the rising prevalence，ASD has become one of the global public health issues.ASD has serious impacts on lives of children and their families，imposing great economic pressure and heavy spiritual burden on families.Therefore，early detection，and timely diagnosis，as well as early implementation of behavioral intervention and educational intervention，could impact the prognosis of ASD patients and help improve their families' social life.In November 2019，the Canadian Pediatric Socirty （CPS） issued Standards of Diagnostic Assessment for Autism Spectrum Disorder，which is the first ASD diagnosis statement issued by CPS to guiding the community primary healthcare providers.It provides community-based pediatric clinicians with recommendations，tools and resources to perform or assist in the diagnostic evaluation of ASD.This paper interprets this statement and optimizes ASD diagnosis and evaluation strategies，especially to help community pediatric clinicians and primary healthcare providers diagnose ASD as early as possible.
