Start with who is applying and what the project will do
A classroom equipment purchase, an after-school program and a study of how children learn need different funding routes. Start with your applicant type, students served, location and project purpose. A large national education budget is not the amount available to your organization. For a district project, begin with the district grants office and state education agency. For an after-school nonprofit, check your state’s 21st Century Community Learning Centers competition and local foundations. For research on STEM teaching and learning, examine NSF STEM K-12. Treat each route below as a starting point; an active program is not proof that your project or organization qualifies.
NSF STEM K-12: an active research route
NSF STEM K-12, solicitation 25-545, lists proposals as accepted anytime when checked on September 22, 2026. It supports research and development concerning STEM teaching and learning in formal and informal settings. This is a research funding route; do not assume a stand-alone classroom supply request fits. The solicitation lists DRK-12, AISL, CSforAll and Translation and Diffusion as archived and directs relevant applicants toward STEM K-12. It also directs K-12 and informal-learning researchers away from ECR, which now accepts DUE- and DGE-focused proposals. Read the project requirements and applicant rules together. An eligible university or nonprofit may serve school-age learners; the applicant organization and the students who benefit are different things. Use the current solicitation’s award categories and submission instructions when planning a proposal.

21st Century Community Learning Centers: apply through your state
21st CCLC supports academic enrichment outside school hours, particularly for children attending high-poverty and low-performing schools. The federal government awards funds to state education agencies; states run competitions for local subgrants. Eligible local applicants can include school districts, community-based organizations, tribes and other public or private entities. Check the current state notice for eligibility, partner requirements, priorities, award limits and deadlines. There is no single national application deadline for all local providers. If you run an after-school or summer STEM program, start with your state’s current competition page. A federal program description or an old state award announcement does not establish that applications are open today.
Title I, IDEA and Title IV-A: district funding rather than open national competitions
Title I-A and IDEA Part B are formula funding programs administered through states. They are not general national competitions that an outside nonprofit can enter simply because its work benefits students. Ask the district which activities it plans to fund and what partnership or procurement process applies. Title IV-A Student Support and Academic Enrichment guidance describes formula subgrants from states to eligible local education agencies. The program supports well-rounded education, safe and healthy students, and effective use of technology. School enrollment below 1,000 does not by itself establish an automatic $10,000 award, and larger districts are not categorically switched into competitive subgrants. For a district STEM project, confirm your actual allocation, allowable activities and state application process. For an outside provider, distinguish a possible district contract from a grant your organization can apply for directly.
Education Innovation and Research: verify the competition before preparing an application
Education Innovation and Research (EIR) supports evidence-based educational innovation through early-phase, mid-phase and expansion grants. These tracks have different evidence expectations; the current notice determines eligibility, priorities, award amounts and deadlines. On September 22, 2026, the program page displayed a closed application status and an October 14, 2025 deadline. That page does not establish an open 2026 competition. Check the current notice before investing in an application; do not assume a competition will open in a particular month. The Department’s matching-funds guidance states a 10% contribution requirement, with cash or in-kind contributions, rather than a blanket 100% match for expansion grants. Confirm how the applicable notice treats your proposed match and document it in the budget.
STEM teacher development: keep Noyce on a watchlist
The Robert Noyce Teacher Scholarship Program supports preparation and retention of K-12 STEM teachers and teacher leaders. Its official page was marked “Waiting for new publication” with no upcoming due dates when checked on September 22, 2026. That makes it a program to monitor, not a verified open application window. Read the next solicitation for eligible lead applicants, partnership requirements and deadlines. A teacher seeking an individual scholarship should also distinguish an institution’s funded Noyce project from NSF’s competition for project awards.
Foundation funding: check the application route before writing a proposal
For a smaller local STEM project, build a shortlist of community, regional and corporate foundations serving your location. For each candidate, verify the current education priorities, geographic limits, eligible applicant types and whether unsolicited applications are accepted. Past grants show what a foundation has funded; they do not prove a current open call. Compare the requested project size with actual published award guidance. Confirm whether a school, district, independent nonprofit or fiscal sponsor must apply. If the foundation only funds invited partners, keep it separate from opportunities you can act on now. Avoid spending days on a proposal before finding a current submission route.
Do not treat ESSER closeout money as a new 2026 grant
The Department of Education records September 30, 2024 as the ARP ESSER obligation deadline. Later liquidation arrangements concern payment of qualifying prior obligations; they do not by themselves create a new grant application window. This guide’s earlier reference to “ESSER IV” carryover available for new summer programs was unsupported. Do not use it to plan a new application. If your organization already participates in an ESSER-funded project, consult the state’s current instructions and the Department’s liquidation-extension information for that existing award.
Turn a funding search into a shortlist you can use
Search for your students and project, such as “K-12 STEM education,” then add your location and applicant type where supported. For each promising result, open the official notice and answer four questions: Can this organization apply? Does this project fit? Is the application route currently open? Can we meet the deadline and delivery requirements? Keep a short list of current opportunities separate from programs awaiting a new competition. Save the relevant search if you want to return to it as opportunities change. A broader search result can still be useful, but treat a missing eligibility statement or unclear opening date as a question to resolve, not evidence that the opportunity fits. Editing note: On September 22, 2026, this revision checked the linked federal program routes and corrected archived-program, matching-funds and ESSER claims. It removed unsupported national budget figures and predicted competition dates. State competitions and individual foundation application windows were not independently verified; check their current notices.
