The U.S. Department of Education Office of Special Education and Rehabilitative Services is another great resource for grants and funding. You can check the Federal Register for information about captioning grants and applications.

The Educational Technology, Media, and Materials for Individuals with Disabilities Program (CFDA 84.327) provides millions of dollars in grants and awards each year. Grants are provided to support research and development of universal design technologies; funding is also available to support media-related activities, such as video description and captioning, for use in classrooms. The proposed budget for the 2015 fiscal year includes $24.49 million for continuation awards and $3.56 million for new awards. While 2015 applications are not yet available, you can view the 2014 application to better understand the eligibility and application requirements for the grants.
