Preschool Deployment of Evidence-Based Social Communication Intervention: JASPER in the Classroom.

Ya-Chih and colleagues trained preschool teachers to run JASPER during circle time and free play.

Kids with autism were split into two groups. One group got JASPER right away. The other waited eight weeks.

Teachers learned to sit face-to-face, match toys, and wait for the child to lead. Coaches watched and gave tips until each teacher hit 80 % fidelity.

Children in the JASPER group played longer with others, pointed more, and used new words.

Their cognitive scores also rose compared with the wait-list kids.

Teachers kept high quality even after coaches stepped back.

Gevarter et al. (2021) and Wetherby et al. (2018) show parents can get the same social gains at home through short Zoom calls. Together the studies paint one clear picture: both teachers and parents can boost joint attention when they follow a simple script.

Bearss et al. (2025) tried a different staff-training RCT and saw only mixed child results. The difference? JASPER gave teachers toy-based practice plus live feedback, while RUBIES gave para-educators only manuals and Zoom. The lesson is that hands-on coaching beats packets.

Allen et al. (2001) did an earlier teacher study using FCT. They cut problem sounds and taught one-word requests. JASPER keeps that communication core but adds shared play and joint looks, showing the field has moved from "stop the noise" to "build the relationship."

Vivanti et al. (2014) moved ESDM into community childcare and also saw gains. Both papers prove that lab-born autism programs survive the jump to real classrooms when staff get steady coaching.

You can bring JASPER into public preschool without hiring extra staff. Give teachers a one-day workshop, a toy bag, and weekly 30-minute coaching. Expect kids to play together longer, point, and talk more within two months. Start with one classroom, track fidelity with a simple checklist, and expand once scores hold steady.
