The Investing in Innovation (i3) Fund is a tiered-evidence program that aligns the amount of funding awarded to grantees with the strength of the prior evidence supporting the proposed intervention. One of the goals of i3 is to build strong evidence for effective interventions at increasing scale. The i3 program requires grantees to conduct an independent impact evaluation. This report, from the National Center for Education Evaluation and Regional Assistance (NCEE), assesses the quality of the 67 i3 grant evaluations completed by May 2017 and summarizes the findings of the evaluations. The report found that 49 of the first 67 completed i3 grant evaluations were implemented consistent with What Works Clearinghouse (WWC) evidence standards and 12 of the evaluations found a positive impact on at least one student academic outcome.
