Absolutely share her scholarship amount with the other schools she is seriously considering. That is part of the recruiting management process. It is a competitive situation for these schools, both the D3 schools which are competing for her on the academic side and the D2 schools which are stacking scholarship support.
This is no different than car shopping - You must play the Camry against the Accord and see who can give you the better deal.
As she is going into her senior year, now is the time to share her scholarship status with all the schools. Remember that it is right now that college coaches know who will not return from this year's roster, because season practice has started and they know who they will cut. Because they know this, they also know what additional money they will have available in 2014!
Lastly, remember that this is not the college coach's money, it is numbers on a piece of paper. But, it is your money. Too many families are hesitant or shy about putting their scholarship offers and needs on the table, because money can be an uncomfortable subject. To make is more mentally manageable, I constantly remind families that it is not 'real' money for the coach or school, but it is real money for the family.
