Effectiveness and feasibility of the early start denver model implemented in a group-based community childcare setting.

Researchers put the Early Start Denver Model (ESDM) into a real daycare.

Twelve toddlers with autism joined a 1:the group led by regular childcare staff.

Kids stayed in the program for one full year.

A second group got the center’s usual lessons.

Both groups took the same tests before and after.

The ESDM group moved through developmental milestones faster.

They also understood more words on the Mullen test.

The gap over the study period was large enough for parents and teachers to notice.

Standard daycare did not show the same jump.

Chang et al. (2016) ran a similar classroom test with JASPER.

Both studies prove teachers can run naturalistic autism lessons in busy group rooms.

ADiemer et al. (2023) used PECS in a clinic and saw speech gains too.

Their kids were older and worked one-on-one, so the setting differs.

Bustos et al. (2021) asked staff how they felt rolling out comprehensive ABA.

High satisfaction scores match the current study: community teams can do ESDM without burnout.

You no longer need a 1:1 clinic room to start ESDM.

If you consult for a preschool, train the aides to mix ESDM goals into circle time and free play.

One short coaching session per week kept fidelity high in this study.

That small tweak may double the hours a child gets evidence-based teaching each week.
