Last month, Steve Noble blogged about the Department of Education updating their Math guidelines for NIMAS publisher Files. The "dear colleague" letter from the US Department of Education recommended that when a state or local school district requests content containing math from publishers, they should require that the math be encoded using MathML 3 to maximize accessibility.

Publishers will have to make sure that all of their materials are in the NIMAS format, a national standard for K-12 textbook accessibility that is based on the DAISY standard. The new math guidelines are part of more general guidelines on how to author all of the parts of a DAISY book. Most publishers already meet the non-math parts of the guidelines, and the new additions should help publishers more smoothly transition towards making math in their textbooks and supplemental material accessible. We've updated the MathFlow set of tools to MathML 3 so you can use those tools to implement the guidelines.

Design Science is proud to have played a key role in reviewing and suggesting improvements in the initial drafts. We continue to lead the way towards greater math accessibility with improvements in our latest versions of MathPlayer and MathType. If you want to find out more about math accessibility, check out our math accessibility pages. We have some exciting announcements planned for the coming months, so sign up to this blog to be the first to hear about them.
