Inclusion Criteria

• 2:0 to 5:11 years at the time of consent,

• no more than 60 minutes of 1:1 speech therapy per week

Exclusion Criteria

• Children who have a primary language other than English
• parent or child diagnosed with severe psychiatric disorder or unstable medical problem
• previous adequate trial of pivotal response treatment resulting in parent meeting Pivotal Response Treatment fidelity of implementation at baseline

Arm && Interventions

Group	Intervention	Description
Pivotal Response Treatment Online (PRT-O) Course	Pivotal Response Treatment Online (PRT-O) Course	The PRT-O Online Course (PRT-O) will consist of 10 online lessons completed asynchronously through the Stanford LearnMed Online CANVAS Platform. Parents are expected to view the 10 lessons over the course of a 12-week study period, complete worksheets, and to practice PRT at home.

Primary Outcome Measures

Name	Time	Method
Change from Baseline on Parent Fidelity of Pivotal Response Treatment Implementation as measured on the Home Video Observation (HVO)	6 Weeks and 12 Weeks	Parent Fidelity of Pivotal Response Treatment Implementation will be rated from 10 min HVO by trained coders naïve to treatment assignment and timepoint using established operational definitions from prior PRT studies (e.g., Hardan et al., 2015; Gengoux et al., 2019).
Change from Baseline on Child Functional Verbal Utterances as measures on the Home Video Observation (HVO)	6 Weeks and 12 Weeks	Child Functional Verbal Utterances will be rated from 10 min HVO by trained coders naïve to treatment assignment and timepoint using established operational definitions from prior PRT studies (e.g., Hardan et al., 2015; Gengoux et al., 2019).

Secondary Outcome Measures

Name	Time	Method
Change from Baseline on the Clinical Global Impression Scales (CGI)	6 Weeks and 12 Weeks
Change from Baseline on the Vineland Adaptive Behavior Scales -3 (VABS-3) Communication Domain	12 Weeks
Change from Baseline on the MacArthur-Bates Communication Scales (CDI)	12 Weeks
