All Included in Mathematics — Expansion and Dissemination (AIM-ED) was a four- year ITEST- SPrEaD project to expand, disseminate, and further understand the 40-hour, face-to-face mathematics professional development program for elementary teachers developed in Project AIM: All Included in Mathematics (DRL- 1020177 ).

AIM-ED took Project AIM from a Design and Development Research model to an Impact Study that examined the efficacy of the intervention (IES & NSF, 2013). It implemented the professional development in the new partner district, Johnston County Schools, with substantially less support from the project team to facilitators and used a quasi-experimental research design to test the effects of the professional development on both teacher and student learning. AIM-ED was designed to examine the hypothesis that, when implemented with fidelity, not only teachers learn from AIM-ED, but students in the classrooms of AIM-ED participating teachers also benefit.

Research Activity

TERC was the project’s external evaluator.


AIM-ED impacted mathematics classrooms, fostering the implementation of high-quality discourse and supporting learning for all students. By providing teachers with strategies that support the implementation of high-quality discourse that respect all students’ backgrounds, the expansions included in AIM-ED helped promote equitable mathematics instruction for all children across the nation.
