More Gwinnett County schools are meeting the academic requirements of a contract with the state that measures classroom proficiency, but a handful of schools have repeatedly missed the benchmarks.

State officials released a report last month that found 113 of 121 Gwinnett schools met the requirements during the 2013-14 school year. Five fewer Gwinnett schools met the requirements during the 2012-13 school year.

Gwinnett, Georgia’s largest school district, joined the state’s Investing in Education Excellence program in 2009, better known as IE2, which gives school districts more flexibility to implement programs that improve student performance.

The state report said three Gwinnett high schools – Duluth, Meadowcreek and Norcross – have not met the benchmarks in three of the five years of the initial IE2 contract, which means those schools did not fulfill the contract. Gwinnett school leaders and the state have agreed on a new contract.

Much of the trouble for those three schools was in math, the report said. State officials recommended additional oversight from Gwinnett of those schools. Gwinnett officials said they have school improvement plans for the three high schools, as it does for all schools, that it hopes will increase their performance.

“That helps (state officials) to understand what we’re doing and what we’re doing to improve,” said Steve Flynt, the district’s chief strategy and performance officer.
