SAVANNAH, Ga. (WSAV) — The Savannah Chatham County Public School System (SCCPSS) responded to a list put out by state that showed several schools were under performing on Tuesday. Within the SCCPSS, 18 schools were classed as underperforming under the Georgia Governor's Office of Student Achievement's (GOSA) standards, which would make students at those schools eligible for a private school voucher. However, the list has since been taken down, with the state citing the need to clarify their calculations. SCCPSS officials expressed their displeasure with the list and the legislation that led to the list being released at a press conference on Tuesday. The legislation is called the Georgia Promise Act, which is a new law that allows parents of children in Georgia who are zoned for what that state considerers to be an underperforming school to receive up to $6,500 to send them to private school. The superintendent said Tuesday she was unsure about what specific criteria the GOSA was using to rank schools. Though, officials confirmed they were aware of a basic formula, one that GOSA confirmed to WSAV last week. It involves what's called a CCPRI score, which is supposed to be an overall indicator of the academic performance of students at a given school. That score was previously calculated by the Georgia Department of Education, but now, GOSA is the agency doing those calculations. District officials said that change has contributed to the disconnect about the criteria being used to rank schools. "There's some confusion in it obviously," Chief Public Affairs and Admin Services Officer for SCCPSS Kurt Hetager said, "but I do want to reinforce that at the core, the basis of what it stands for is something that our board has over the years said through their legislative priorities, we don't need this, we don't want this and we don't support bills that create unfunded mandates and siphon dollars away from the public school systems that really need those resources in their local communities." SCCPSS seeks community feedback for school upgrades SCCPSS Superintendent Dr. Denise Watts said she wants parents to focus on more than numbers on a list and consider what the school their child is zoned for can really offer. "I never want to diminish a parent's right to choose a school that they think best fits their child's needs but we are working daily to meet the needs of our students in our school systems," Watts said, "and we believe that we can provide a high-quality public education here in Savannah-Chatham County Public School System, and we want parents to consider their home school as a first option for their children." While school district officials said they wouldn't engage in speculation about whether the calculations are indeed accurate, SCCPSS officials did talk about the district's ups and downs for 2024 . For high schools, the four-year graduation rate went down. In elementary schools, progress went down, but at middle and high schools, progress went up. It is unclear when the updated list of voucher-eligible schools will be reposted by the state.
