While in the Illinois Senate, Crotty's legislative priorities included health issues and education. She passed legislation to expand state reading assistance grants to grades 7 through 12. Another legislative goal was to increase the state reimbursement rate to school districts for providing special education. She was a co-sponsor of a Bill to create a state administered prescription drug discount buying group for seniors. Beginning in January 2004, seniors were able to save up to 50% on the cost of prescription drugs.
