Please review the official application notice for pre-application and application requirements, application submission information, performance measures, priorities and program contact information. For the addresses for obtaining and submitting an application, please refer to our Revised Common Instructions for Applicants to Department of Education Discretionary Grant Programs, published in the Federal Register on December 7, 2022. Purpose of Program: The EIR program, established under section 4611 of the Elementary and Secondary Education Act, as amended (ESEA), provides funding to create, develop, implement, replicate, or take to scale entrepreneurial, evidence-based (as defined in this notice), field-initiated innovations to improve student achievement and attainment for high-need students and to rigorously evaluate such innovations. The EIR program is designed to generate and validate solutions to persistent education challenges and to support the expansion of those solutions to serve substantially more students. The central design element of the EIR program is its multitier structure that links the amount of funding an applicant may receive to the quality of the evidence supporting the efficacy of the proposed project, with the expectation that projects that build this evidence will advance through EIRs grant tiers: Early-phase, Mid-phase, and Expansion. Early-phase, Mid-phase, and Expansion grants differ in terms of the level of prior evidence of effectiveness required for consideration for funding, the expectations regarding the kind of evidence and information funded projects should produce, the scale of funded projects, and, consequently, the amount of funding available to support each type of project. Early-phase grants must demonstrate a rationale (as defined in this notice). Early-phase grants provide funding for the development, implementation, and feasibility testing of a program that prior research suggests has promise, for the purpose of determining whether the program can successfully improve student achievement and attainment for high-need students. Early-phase grants are not intended to simply expand established practices or address needs unique to one particular context. Rather, the goal is to determine whether and in what ways relatively new practices can improve student achievement and attainment for high-need students. This notice invites applications for Early-phase grants only. The notices inviting applications for Mid-phase grants and Expansion grants are published elsewhere in this issue of the Federal Register. Assistance Listing Number (ALN) 84.411C.
