What ADA Title II transcript requirements actually cover
On April 24, 2024, the Justice Department published a final rule under Title II of the Americans with Disabilities Act. It adopts WCAG 2.1 Level AA as the technical standard for state and local government web content and mobile apps (ADA.gov, 2024). The rule took effect June 24, 2024.
WCAG 2.1 is a W3C accessibility standard, not something the DOJ wrote. By naming it, the rule pulls in that standard's rules for time-based media: text alternatives for audio, captions for video, and audio description for prerecorded video. So the transcript and caption obligations flow from WCAG, and Title II makes them binding on public entities.
Deadlines now hinge on the population you serve
The rule phases in by entity size, and the dates recently changed. State and local governments with a total population of 50,000 or more must comply by April 26, 2027. Entities under 50,000, plus special district governments, have until April 26, 2028 (ADA.gov, 2026).
Those are the extended dates. The 2024 rule originally set April 24, 2026 and April 26, 2027, but a DOJ Interim Final Rule published April 20, 2026 pushed both back by about a year. Treat the 2027 and 2028 dates as the live deadlines.
The 50,000 line is drawn from population, not headcount. It uses U.S. Census Bureau data, and most entities use their 2020 decennial Census population; independent school districts use the 2022 Small Area Income and Poverty Estimates instead. It's the population of the jurisdiction, not the number of people you actually serve.
Where a plain transcript meets the standard
For prerecorded audio-only content, a text transcript is the compliant artifact. WCAG 2.1 Success Criterion 1.2.1 (Level A) requires an alternative that presents equivalent information for audio-only media (W3C, 2018). A recorded public hearing posted as audio, or an audio-only notice, needs a transcript.
Equivalent information is the test. The transcript has to carry what a listener would get from the audio, so meaningful non-speech and who is speaking can matter. A clean, readable audio-to-transcript file is what satisfies the criterion, not a rough draft that drops half the words.
Audio-only is the narrow case, though. The moment there's a synchronized picture, a transcript stops being enough, and the caption criteria take over. That distinction drives most of the compliance work for public video.
Video needs synchronized captions, not a bare transcript
Video with sound is synchronized media, and it needs captions. WCAG puts captions for prerecorded synchronized media at SC 1.2.2 (Level A) and captions for live media at SC 1.2.4 (Level AA) (W3C, 2018). A transcript sitting next to the player doesn't meet either one.
Prerecorded video also carries an audio-description obligation. SC 1.2.3 (Level A) accepts either audio description or a full media alternative, while SC 1.2.5 (Level AA) requires audio description for prerecorded video (W3C, 2018). At the AA target, plan on real audio description, not just a transcript.
Why do the Level A criteria apply when the rule names Level AA? Because AA conformance requires satisfying every Level A and Level AA success criterion (W3C, 2018). That leaves you producing a caption sidecar. You can export a VTT caption file or an audio-to-SRT file and attach it to the player.
The accuracy bar, the exceptions, and the bottom line
Raw auto-captions rarely clear the bar on their own. Both the caption and transcript criteria ask for equivalent information (W3C, 2018), and auto-generated text often drops names, numbers, punctuation, and speaker turns. Closing that gap usually means a cleanup pass, especially on a multi-speaker transcript where speaker turns and crosstalk drive most of the errors.
The rule does carve out five exceptions from the technical standard. They cover archived web content, preexisting conventional electronic documents, certain third-party content, individualized password-protected documents, and preexisting social media posts (ADA.gov, 2024). A preexisting document loses the exception once you use it to deliver a service.
The Justice Department enforces Title II. Anyone who believes a state or local government discriminated based on disability can file an ADA complaint with DOJ. The Department may investigate, which can lead to a settlement or a lawsuit (ADA.gov, 2024).
None of this is legal advice, and the rule holds more detail than one page can. The practical read is simple, though. Inventory your public audio and video, publish clean transcripts for audio-only files and synchronized captions for video, and work back from your 2027 or 2028 date.
