If you ask for a reconsideration, when AtW reply they say something like "This decision is final and there is no further review process within Access to work. As your continued dissatisfaction relates to our policy, guidance and the decision we have given you, we are unable to escalate this issue any further on your behalf".
Many Deaf people think this means they can't complain. This is not true. If you think AtW have not assessed your needs properly, or have made mistakes in their decision, etc. then you can complain.
If you aren't sure how to complain, contact DeafATW.
