Dependent Education that goes with 100% P&T

I was recently made 100% P&T.  For the education benefits that go along with this the question is:  I have a 24 year old daughter starting grad school soon.  I believe she is still eligible to be my dependent until age 26.  She is going full time.  Am I correct in my thinking?  Do I submit something to the VA intake center to get her back on as a dependent so that she can receive the education benefit at her school?  I think its roughly $1000 a month.

Thanks
