Substantial is a national nonprofit on a mission to unlock the potential of substitute teaching.

We use human-centered design to create tools that help districts rethink how they recruit, train and support substitute teachers:

-SubSchool: Online PD for subs - online courses, resources and facilitated learning communities.

-SubPlans: Streamline the process for creating and managing sub plans, making it easy for schools to provide substitute teachers the information they need to have a successful day.

Substantial was incubated at Stanford's dschool and is an alumni of the AT&T Aspire EdTech Accelerator.
