There are not enough literacy programs in general and many programs do not have resources for technological aids, attendant care, daycare, accessible transportation or making a building accessible.
Another barrier is the personal barriers that many people face when going back to school. For people who have a low literacy level, school (if they had the opportunity to attend) may have been a bad experience. People may have been labelled or told that they would never learn. People may have been segregated into special classes and not had the same opportunity to learn to read as their peers. For these and countless other reasons people may be afraid to go back to school.
For some people with disabilities overcoming these barriers is only the beginning. For people who are deaf or non-verbal, finding an adequate literacy program is the next hurdle. Communication is a basic component of literacy and people who are deaf or non-verbal communicate by methods other than speaking and hearing. Therefore, gaining literacy skills becomes particularly difficult.
Communication is a necessity for full participation in this society. Many people who communicate by methods other than speaking and hearing are isolated from mainstream society. The basic tool that literacy teachers use, communication by speaking and hearing, cannot be used. This issue warrants further discussion.
