After grading the academic performance of 535 schools in and around Bexar County, a study by ChildrenAtRisk.org found not all of them had passed with flying colors.
Dr. Bob Sanborn, the nonprofit's president and CEO, said although there are excellent schools in the San Antonio area, "There are really too many schools that don't make the grade."
Sanborn said the rankings were based on standardized tests for reading and math, test score improvements, and graduation rates.
He said 14 percent of the schools earned As, but 10 percent were given Ds and even Fs.
"We can't keep doing the same thing and expect different results," Sanborn said.
To help make up for the lack of state funding, he said research shows what works especially in high-poverty schools.
Sanborn said high expectations, strong leaders, longer school days, data for tracking student progress, and teachers with a missionary zeal can make a difference.
However, he said, funding remains critical.
"There still needs to be that pressure for more funding and turnaround from the state level," Sanborn said.
Yet again the study's top-ranked middle school and high school are Young Women's Leadership Academy, in the San Antonio Independent School District, and Health Careers High School, in the Northside Independent School District.
Vineyard Ranch, in the Northeast Independent School District, is this year's top-ranked elementary school.
Randolph Field ISD also ranked first among area school districts.
Sanborn said, "Congratulations to the faculty and student body of all our campuses."
