Efficacy Trial

Our Efficacy Trial seeks to confirm whether ASSISTments is effective in North Carolina, a setting which more closely reflects the population of the U.S. Please visit our requirement site to apply to participate.

In a previous IES-funded efficacy study, conducted in Maine, ASSISTments was found to lead to beneficial impacts on student learning outcomes. Our Efficacy Trial will examine the impacts of this intervention with a more diverse sample, use the State standardized test as the student outcome measure, and rely on mathematics coaches (instead of the intervention developers) to provide professional development and support to teachers.
