What VA benefits are available to help pay for a graduate degree (already used Post 9/11 GI bill for undergraduate degree)?

I looked at your profile and it looks like you are in Sacramento. Check with the California Department of Veterans Affairs http://www.calvet.ca.gov. They have an office at 2007 19th St, Sacramento, CA, 95818. I don't know California, but in my state there were benefits unique to the state and they had easily accessible counsellors who could walk you through things.

Beyond that, if you are currently employed, check with your HR department. Some companies provide tuition reimbursement up to $5,250 per years.

The VA Voc Rehab program was VERY beneficial for me. I was fortunate to have transferred to a progressive thinking counselor after a big disagreement with the first Bubba. In addition to a Masters in Education they funded a Post-Masters Certificate in Alternative energy. To get me ready for the work force they also funded three Dale Carnegie programs plus four Landmark seminars. Yes, I was a mess. I am now employed and doing well. I am the most healthy I've ever been in my life. All you need is a 10% disability rating to receive benefits. I have a coworker who applied using what's called a "Memo Rating". He used his service medical records (and Purple Heart) to show he will more likely than not have at least a 10% disability. This allows him to start the process while waiting for the official decision on his disability claim. Unfortunately, the Voc Rehab counselor you draw can determine what amount of help you will receive. My first counselor, "Victor" at the Roanoke Office was extremely unhelpful and even stated, "At your age I don't think additional education would help. Why don't we look at another program to improve your quality of life so you can enjoy your retirement." That was four years ago and now I'm feeling proud as a tax payer. I am glad I asked for a different counselor who believes that middle aged vets can learn new skills and contribute to society. (Thank you Merri in Detroit.) Voc Rehab is a fantastic program but like many things in life you must be determined and persistent.
