When Harlingen Consolidated Independent School District school board member Greg Powers handed Corina Flores her high school diploma on August 27, a mammoth smile overtook her face.Flores should have graduated in 2005, she said. But when she could not pass her TAKS tests, which were required for graduating, she quit school to work as a cashier.“If I could do it all over again, of course I wouldn’t have quit,” Flores said. “I had to learn that education matters. It’s something that no one can ever take from you.”
