The Sacramento City Unified school board is reviewing one of its most politically charged decisions: whether it made the right call in 2003 in giving Sacramento High School to a nonprofit group run by retired basketball star Kevin Johnson. Johnson's St. HOPE Corp. has asked permission to run Sacramento High as a charter school for another five years. The charter school's success has become a matter of debate. Some teachers left after a couple of years and say St. HOPE hasn't lived up to its promise. Sacramento Charter High School has not attracted the nearly 2,000 students it was intended to serve. But about 1,100 students are there now, and they say it's a place where they feel safe, cared for and academically challenged.
