ATLANTA (AP) — The Georgia Senate has approved changes to a tax credit program that provides scholarships for children to attend private schools.

State senators voted unanimously Thursday to support the changes, which include a reporting requirement on the average household income of recipients and requires eligible students to have attended public school for at least six weeks with a few exceptions.

Under the system, people can receive state tax credits by giving nonprofit scholarship providers donations of up to $1,000 for individuals and up to $2,500 for married couples.

The Southern Education Foundation had raised concerns that donors may have been allowed to earmark donations, although supporters had argued that was prohibited under the law. The Senate bill would add language specifically prohibiting that.
