If you have ever watched USAC reviewers quietly change your site data, you are not alone. Last year, USAC modified Community Eligibility Provision (CEP) data on roughly one out of every twelve funding requests. Most of those changes were not the result of bad data. They were the result of where the data came from.
Funding Year 2025 funding decision data, tracked in E-rate Manager®, shows that 4,769 FRNs received a CEP-related PIA action, including 3,772 changes to the CEP base year alone. In the overwhelming majority of those cases, Program Integrity Assurance (PIA) reviews shifted the application data to match what state or third-party sources already showed. If your CEP base year, percentage, or site assignments do not match what USAC can verify, PIA will quietly update your application to match the validated source. That can delay your funding decision and consume admin window time you cannot get back.
The good news is that almost every one of these corrections is preventable. Here are the six issues that show up most often, and what to do about each one.
1.Base year confusion is the most common error. Applicants often enter the current year or the filing year as the CEP base year. The base year is actually tied to when the Identified Student Percentage was established for the four-year CEP cycle. PIA frequently shifts it back. If your district started its current CEP cycle in 2024, for example, that is the base year, even if you filed the Form 471 in 2025. Confirm the base year on your original CEP approval letter before you file.
2. PIA defers to the validated source, not the applicant. Here is the thing most applicants do not realize. If the percentage or base year on your application differs from what state or third-party data shows, USAC will not flag it back to you for clarification. The stock language on these corrections reads “modified from [year X] to [year Y] that could be validated based on third party data.” The validated source wins by default. Match it from the start.
3. ISP is not the same as NSLP. This one catches a lot of applicants. The Identified Student Percentage is the raw number. The NSLP equivalent is the ISP multiplied by 1.6. Some state reports present the multiplied value already, and EPC will apply the 1.6 multiplier again on top of it. The result is an inflated discount and a guaranteed PIA correction. Always confirm which value your state report is showing before you enter it.
4. Mixed districts need site-level accuracy. Many districts have a combination of CEP and non-CEP schools. A district-wide percentage will have questions under PIA review. Apply the correct data, CEP or NSLP, at the individual site level. One size does not fit all here.
5. Grace year questions are easier than they look. USAC will sometimes ask whether a site is in its fifth year, the grace year. If you have the original CEP approval letter showing the base year and the full cycle timeline, that single document usually resolves the question without further back-and-forth.
6. Pull from a validated source during the admin window. If you only do one thing from this list, do this. Source your CEP data directly from your State DOE or another third-party source before you build the application. Of the 3,772 base year changes made in PIA review in FY2025, more than 3,500 cited third-party data as the source of the correction. Starting from that source means there is nothing to correct.
If you file as a consortium, this filing season warrants extra attention. In FY2025, USAC modified CEP base years on 25.4% of consortium-filed FRNs, compared to 7.0% of district-filed FRNs. That is nearly four times the correction rate. The fix is the same as for any other applicant, but the stakes are higher because of the number of sites involved.
If your district or consortium has CEP sites, the strongest move you can make this filing season is to validate every percentage and base year against your state’s data before you submit. It saves additional review time with USAC, it protects your funding timeline, and it lets you close out the admin window with one less thing to worry about.
