Does making our school web content accessible mean I cannot use multimedia on my site?

No. It means instead that you must design multimedia in such a way that individuals with disabilities, particularly those with sensory impairments, can access it or that you must provide an alternate format for the content in the multimedia. For example, a video clip can be captioned for those who are deaf and audio-described or transcribed for those who are blind and using speech or Braille technology for access. A good source of information about making multimedia accessible to people with disabilities is the National Center for Accessible Media (NCAM).
