On June 30, 2021, Colorado HB21-1110 strengthened the Colorado law for protection against discrimination against persons with disabilities; specifically, it requires the accessibility of all digital government information technology. To comply, all digital experiences provided by the [insert your organization] must meet all applicable Level A and AA success criteria of the current non-draft version of the Web Content Accessibility Guidelines (WCAG).   

Therefore, in order to comply with Colorado law, we are informing you that [product name] must meet these WCAG guidelines by July 1, 2024. To confirm compliance, functional accessibility evaluations or manual testing evaluations for [product name] should be performed by your company’s experienced internal accessibility team or a certified third-party testing firm at least [cadence such as once per year and/or for every version upgrade] with the evaluation results to be provided to the [insert your organization] within [x number of days] after testing. Please note that the testing results can be provided in the form of a manual testing report or accessibility compliance report such as a completed Voluntary Product Accessibility Template (VPAT). If the [product name] cannot meet these compliance standards or you cannot provide these evaluations, the [insert your organization], at its sole discretion, may terminate any contract between the parties without recourse to obtain legally compliant platforms.     

By receiving this letter, [company name providing the product] hereby certifies that it will meet Colorado’s statutory compliance requirements no later than July 1, 2024. In so certifying, [company name providing the product] acknowledges and agrees that [product name] will ensure compliance in testing, maintaining, and updating the product, and will swiftly resolve and remediate all accessibility issues discovered while the [insert your organization] utilizes [product name].

Please feel free to contact [contact information] if you have any questions or would like to discuss this further and collaborate on achieving full accessibility with your product. We look forward to continuing our partnership with you.
