There are some grants and awards and funding streams, organizations etc to encourage women in film (WIFV or Geena Davis Institute, the Directors List) and/or minorities in film. Some groups are well established with great educational programs. I'm talking about non-disability film-related organizations with successful history in supporting and promoting individual artists and their work.
Funding/Supporting Disability programs/orgs to do the same, may be helpful, but pushing (via funding disability applicants or disability projects etc) within these existing programs to ACTIVELY include disability could ensure a more integrated approach to the industry (esp. one that doesn't have strong disability representation yet thereby taking advantage of these organizations networks), build more accessible industry systems and create a better pipeline mechanism.
