If I may add something as well about the service-connected disability rating, when a service member is in the process of transitioning out or has transitioned out recently, they do not have to wait for the entire process to take place for their disability rating. If there is medical documentation that the VA can use to determine if the disability will be rated at 20% or higher, that decision can be expedited in as much as three days. Then the veteran can begin the rehabilitation process while he or she awaits the final decision from the VA. Even if that final decision on the disability rating becomes less than 20% based on all the evaluations, they can still remain in the vocational rehab program until the point of rehabilitation.
