Polk School District is celebrating a historic academic achievement after posting its highest-ever Georgia Milestones assessment scores in nine of the 12 tested subject areas, according to results released by the Georgia Department of Education. District officials said students achieved all-time high scores in every grade level tested in mathematics, including third through eighth grades. Record performances were also recorded in eighth-grade physical science, high school biology and eighth-grade Georgia Studies. ”These scores demonstrate the commitment to providing high-quality instruction to all students, every day throughout Polk School District,” Lumpkin said. Georgia Milestones assessments measure student achievement in grades 3-8 through End of Grade (EOG) tests and in selected high school courses through End of Course (EOC) exams.
