SAN ANTONIO – Pre-K 4 SA officials are hopeful that voters will reauthorize the sales tax that provides most of the program’s funding at the polls this spring. The program runs four centers around San Antonio that offer free and reduced-price prekindergarten education. Its other components include professional development for educators and providing grants that support students in other programs. So the program’s board of directors is asking the San Antonio City Council to get the issue back onto the ballot this year for voters to decide whether to reauthorize the tax. Pre-K 4 SA officials say they plan to expand access to prekindergarten for 3,000 families through its centers and at partner programs.
