UDL and Intellectual Disability: What Do We Know and Where Do We Go?

Kavita and her team read every paper they could find on Universal Design for Learning (UDL) used with students who have intellectual disability (ID).

They looked at studies from 1984 through 2016. They did not run a new experiment; they simply mapped what had been tried.

Most teachers use only bits of UDL—maybe captioned video or choice boards—but skip the rest. Whole-school UDL plans for kids with ID are rare.

No study linked a full UDL package to clear student gains. The evidence is still patchy.

Romero (2017) says behavior analysts must help write disability policy, not just deliver services. Kavita’s map shows we still lack the data policy writers need.

Friedman et al. (2018) found most state waivers still allow restraint for people with ID. UDL’s goal is to prevent crisis moments that lead to restraint, yet the papers barely talk to each other.

Siklos et al. (2006) showed parents of kids with Down syndrome want more community inclusion. UDL could fill that gap, but the studies Kavita found rarely measure inclusion outside the classroom.

If you write IEP goals or coach teachers, push for full UDL pilots that include students with ID and collect data. Track simple things: time engaged, number of adult prompts, peer interactions. Until we show clear gains, schools will keep using UDL like a buffet—picking only the easy items.
