Lakeland High School had a party at school Friday to celebrate the school’s full accreditation victory.

Roughly 900 students packed the high school’s track during last period for the pep rally.

Lakeland was accredited with warning in 2012 after failing to meet state benchmarks on mathematics standardized test scores. The school boosted math scores by 16 points this year, jumping from 54 to 70 — the lowest passing benchmark — to pass the Standards of Learning test, principal Douglas Wagoner said.

After Lakeland’s marching band performed Friday, school officials congratulated cheering students and teachers.

The school’s JROTC broke out its new drone and recorded a bird’s-eye-view video of the student body singing the school song.

“You celebrate your successes,” Wagoner said. “The kids worked hard, teachers worked hard and the scores … show that all their work made a difference.”

Lakeland received extra training from the staff, as well as significant assistance from three math specialists from the division’s central office, Wagoner said. The specialists focused on designing lesson plans aligned with state standards, assessments were written similarly to the Standards of Learning and classes taught at a cognitive level to the tests, Wagoner said.

“The teachers really put their noses to the grindstone and were open to change and advice,” Wagoner said. “They put in a lot of extra hours after school and on weekends.”

Wagoner also recognized three students who earned perfect SOL test scores: Jermaine Austin, William Campbell and Christopher Defreeuw.
