Missouri has a state-specific IT accessibility law, RSMo 161.935 (originally RSMo 191.863, transferred in 2014), requiring all state agencies and public four-year and two-year colleges and universities to develop and procure accessible information technology unless an undue burden would be imposed. The Missouri Assistive Technology Advisory Council (MoAT) together with the Office of Administration ITSD set the standards and adopted WCAG 2.2 Level A/AA (effective 10/5/2025, compliance by 4/6/2026), with the statute's IT definition aligned to Section 508. Enforcement is complaint-driven and review-based, consistent with Section 508; the statute provides no private right of action and no statutory damages or per-violation fines. The federal ADA Title II baseline (WCAG 2.1 AA, compliance Apr 26 2027 / 2028) also applies to Missouri state and local government.

What the law requires

• Responsible agency Missouri Assistive Technology Advisory Council (MoAT) and the Office of Administration Information Technology Services Division (ITSD/OIT) (at.mo.gov/ict-laws-standards/) (opens in new tab)
• Adopted standard WCAG 2.2 Level A and AA, adopted by the Missouri Assistive Technology Advisory Council on September 13, 2024 (superseding the prior WCAG 2.1 A/AA standard). The statute defines information technology consistent with Section 508 of the federal Rehabilitation Act and references Section 255 of the Telecommunications Act; the technical conformance standard is WCAG 2.2 A/AA.
• Who it covers Each department, office, board, bureau, commission, or other unit of the executive, legislative, or judicial branch of state government, including public four-year and two-year colleges and universities, when developing, procuring, maintaining, or using information technology or administering contracts/grants involving IT. Covers public sites, applications, intranets, and internal agency communications.
• Private right of action No / Unclear - The statute does not create an express private right of action. Enforcement is complaint-driven: RSMo 161.935 directs the council and ITSD to establish complaint procedures consistent with Section 508 for individuals with disabilities alleging non-compliance, and to conduct accessibility reviews. No state court cause of action with statutory damages is provided in the statute.
• Statutory damages / penalties None - enforcement/complaint-driven. RSMo 161.935 specifies no per-violation fines, monetary penalties, or statutory damages. Remedies operate through internal review procedures and Section 508-consistent complaint processes rather than statutory damages.
• Exemptions Undue burden exemption: compliance is required 'unless an undue burden would be imposed on the department or agency.' The Section 508-aligned framework it incorporates also recognizes fundamental-alteration-type limitations consistent with federal accessibility law.
• Governing authority RSMo 161.935 (originally enacted as RSMo 191.863 in 1999, transferred to 161.935 in 2014); part of RSMo sections 161.900 to 161.945. The Section508.gov state list still cites the legacy number 191.863.
• Compliance deadline State-specific: the WCAG 2.2 A/AA standard became effective 10/5/2025 with a 6-month compliance deadline of 4/6/2026. The separate federal ADA Title II baseline (WCAG 2.1 AA) deadlines of Apr 26 2027 / Apr 26 2028 also apply to Missouri state and local government entities.
