OKO Labs builds software that brings students together to talk through mathematics. A product premised on every student having a voice in the conversation has an obligation to be usable by every student. Accessibility is a design requirement for us, not a compliance exercise.
Conformance target: WCAG 2.2 Level AA
Report date: August 26, 2026
Our conformance target. OKO targets conformance with the Web Content Accessibility Guidelines (WCAG) 2.2 at Level AA. WCAG 2.2 Level AA incorporates all Level A and AA success criteria from WCAG 2.0 and WCAG 2.1, including the WCAG 2.1 Level AA requirements referenced in state K-12 software accessibility statutes such as Colorado HB21-1110.
Where we stand today. OKO's application interface substantially conforms to WCAG 2.2 Level AA. Every student-facing and teacher-facing workflow can be completed using a keyboard alone and with a screen reader. Six success criteria are reported below as Partially Supports. Three of those six concern mathematics problem content that OKO sources from third-party high-quality instructional materials providers rather than the OKO interface itself; that content is under active audit and remediation. The other three are a layout reflow limitation at extreme browser zoom, one below-threshold contrast element in the page footer, and the absence of live captioning for student-to-student speech. Each is itemized with a target date in the Remediation Roadmap.
Beyond the standard. OKO's session experience is multimodal by default. Problem text and facilitator prompts are rendered on screen and read aloud through built-in text-to-speech, and students participate by speaking as well as by typing and clicking. This benefits students with reading difficulties, students with low vision, and multilingual learners. It is additive to the criteria below, not a substitute for them: built-in audio does not replace screen reader support, and OKO does not report it as such anywhere in this document.
If you encounter an accessibility barrier in OKO, or need content in an alternate format, contact us at support@okolabs.ai with the word Accessibility in the subject line. We aim to acknowledge every report within three business days and to give a remediation assessment within ten. Reports from students, families, teachers, and district staff are all welcome, and no account or contract relationship is required to submit one.
This report covers the OKO student session experience and the teacher-facing controls and reports, accessed via web browser on Chromebook and on macOS. It reflects the product as of August 2026, based on evaluation conducted June 15–17, 2026. Conformance is reported against WCAG 2.2 Level AA, which incorporates all Level A and AA success criteria from WCAG 2.0 and WCAG 2.1.
This is a self-evaluation. It was conducted by OKO Labs personnel familiar with the product's functionality and intended use, using the automated tools, manual keyboard testing, and assistive technology testing described under Evaluation Methods Used. No third-party accessibility audit has been commissioned to date. OKO has not inflated any conformance level in this report; where the evidence supported either reading, the lower level was recorded.
OKO's mathematics problem content draws on high-quality instructional materials (HQIM) aligned to state standards, sourced from multiple third-party providers. Conformance of the application interface has been evaluated directly. Problem content is under ongoing accessibility audit and remediation, and several content-level criteria are reported as Partially Supports to reflect variability across sourced items. Remediation is sequenced by usage volume, so the most frequently assigned content is addressed first. See the Remediation Roadmap.
OKO is not being evaluated at WCAG Level AAA. In accordance with the VPAT 2.5Rev Best Practices for Authors, the Level AAA criteria table has been removed from this report rather than left unanswered.
OKO was evaluated against WCAG 2.2 Level AA using a combination of automated tools and manual testing, including keyboard-only navigation and screen reader testing. Testing was performed by team members familiar with the product's functionality and intended use. Automated scans preceded manual testing so that mechanically detectable defects were remediated first and manual testing time was spent on issues only a human evaluator can surface.
This report covers the degree of conformance for the following accessibility standards and guidelines:
These are the definitions published by the Information Technology Industry Council (ITI); OKO has not modified them.
Not Evaluated is not used in this report; it is permitted only for Level AAA, which is not covered here.
When reporting on conformance with the WCAG 2.x success criteria, they are scoped for full pages, complete processes, and accessibility-supported ways of using technology, as documented in the WCAG 2.0 Conformance Requirements. Unless an exception is noted, each criterion was verified through automated testing (Axe, Lighthouse) and manual keyboard and screen reader testing (ChromeVox, VoiceOver) across the workflows above.

Six criteria are reported as Partially Supports. Target windows are stated by calendar quarter; progress is reported in each reissue.
This Accessibility Conformance Report describes the results of OKO Labs, Inc.'s self-evaluation of the OKO web application against the standards above, as of the report date. It is provided for informational purposes to assist customers and prospective customers in making preliminary assessments of the product's accessibility. It reflects OKO's good-faith assessment based on the evaluation methods described and is not a warranty, guarantee, or certification of conformance. Results may vary depending on the browser, operating system, assistive technology, and configuration in use, and on third-party instructional content assigned within the product. Target dates in the Remediation Roadmap are planning estimates, not contractual commitments. OKO Labs, Inc. will provide additional information about any item on request.
