IEP & 504 Updates Log: What Changed and What We Are Watching
The dated log of what we changed and what we are still confirming. A change shows as done only once it is in effect and read against the source.
IEP and 504 rules change through federal rulemaking and guidance and states adjust their own evaluation timelines. This is the running log of the changes and corrections we have made and the items we are actively confirming. A change appears here as a page update only once it is in effect and read against a primary source. An item we are still confirming is labeled as a watch, so you can see what we are checking without us asserting a rule we have not pinned down.

Corrected the IDEA disability-category list
Our independent review caught a draft that had listed developmental delay as one of the thirteen IDEA disability categories in 34 CFR 300.8(a). It is the separate optional category in 300.8(b), which a state may choose to use for children ages 3 through 9. The IEP vs 504 guide now states this correctly.

Alaska corrected to the 60-day evaluation default
An earlier draft listed Alaska at 90 days. That number describes the full combined window from consent through a finished IEP, not the evaluation timeline itself, which follows the federal 60 calendar-day default. The state table now shows 60 days for the evaluation, with the combined outer window explained in the note.

New Hampshire resolved to the 60-day evaluation rule
Some parent and advocacy guides still circulate an older 45-day figure for New Hampshire's initial-evaluation timeline. The current rule, Ed 1107.01(c), requires the initial evaluation to be completed within 60 days of parental consent, so the state table now shows 60 calendar days, read from the rule text rather than the older secondary figure.

Washington evaluation timeline under a recheck
A 2026 OSPI guidance document referencing ESHB 2557 suggests Washington's 35-school-day initial-evaluation window may have been touched by recent legislation. The 35-school-day figure and the WAC citation matched across our sources, so the state table shows it now with a note. We are confirming against the current rule text before making any change.

Watching for a new K-12 Section 504 regulation
The Department of Education has had Section 504 rulemaking activity on its agenda. As of the department's own Section 504 FAPE FAQ, last reviewed June 30, 2025, no finalized new K-12 Section 504 regulation had taken effect, so every page here states the current rule and asserts no pending change. We recheck ed.gov and the Federal Register each review cycle and will log any final rule here the day it is confirmed.
