More than 9,000 students in Greater Houston attend a Harmony Public School.
It’s known as a flagship charter school network in Texas.
It focuses on math, science and technology and recently won nearly $30 million dollars from the federal government.
But not all Harmony charter schools got the same grade in the latest rankings from Children at Risk.
Bob Sanborn is president and CEO of the advocacy group.
“When you look at those top Harmony schools, the data is very clear. Those are pretty good schools. But when you look at the whole thing, you get sort of a mixed bag.”
Children at Risk gave A’s and B’s to half of the Harmony schools. The other half got a C or lower. Three Harmony campuses got an F.
“We’re not really focusing on the reputation. Reputation has built itself in recent years.”
That’s Ozgur Ozer, the chief academic officer at Harmony Public Schools.
“Our aim is progress, continuous progress, so whenever we see we are not doing as well, we just want to focus on there and to improve our programs.”
To improve, Ozer says Harmony will analyze school data and share best practices among all its campuses.
