Important limits
Browser speech voices vary by device. Some diagrams and interactive models may require an adult to describe, enlarge, or reproduce them with manipulatives. The site does not replace human reading, braille or tactile graphics, AAC, sign-language interpretation, or individualized assistive technology required by a student's plan.
Our target
The site is designed toward WCAG 2.2 Level AA, including keyboard access, visible focus, adaptable layouts, readable contrast, and usable touch targets. Automated and static checks cannot replace testing with screen readers, magnification, switch access, and real students.
Report an access barrier
If something is difficult to see, hear, understand, navigate, or operate, prepare a privacy-safe feedback note. Do not include a student's full name, disability, school record, IEP information, or other identifying details.
