ACCESSIBILITY TARGET · WCAG 2.2 AA

Accessibility & Learner Support

The student experience is designed toward WCAG 2.2 Level AA and gives learners more than one way to understand, navigate, and respond.

Navigate

Use keyboard controls, visible focus, clear headings, 44-pixel or larger primary touch targets, and layouts that reflow on smaller screens and at browser zoom.

Understand

Use English or Spanish, readable lesson objectives, immediate feedback, plain-language instructions, source artwork with text explanations, and progress status that does not depend on color alone.

Participate

Use accessible form names and states, written reflections, retryable checkpoints, saved progress, and a 2D keyboard-friendly alternative to the optional 3D House Lab.

Get support

Ask the teacher about pacing, language support, an alternate activity, assistive technology, or another reasonable accommodation. Technical steps are available in the signed-in Help Center.

EQUIVALENT EXPERIENCE

Original PDFs and multimedia

Original teacher PDFs are preserved for staff fidelity and may carry limitations from the source document. Students should use the interactive lesson as the primary experience. Videos used in a course should include captions or an equivalent transcript before publication. Live meeting controls come from the conferencing provider; report a barrier so an alternate path can be arranged.
