No Henry County school scored higher than 50 percent proficient in third-grade English language arts or eighth-grade math, according to the 2018 Georgia Milestones results released by the state Friday.

The Milestones are standardized tests that were first administered in 2015. Test scores place students in four categories: beginning learner, developing leader, proficient learner and distinguished learner.

Students who can’t read by third grade are likely to struggle academically, making that testing year a significant one that can predict future student success. While Henry County’s results indicate that some schools made gains from 2017, the district still has a long way to go.

Superintendent Mary Elizabeth Davis said in a statement that the results "do not represent the best we can do."

“We know that these results are not indicative of the tremendous efforts made every day by our teachers, leaders, and students, but instead signal a need for district leadership to provide clarity for our educators on what teachers will teach and students will learn,” Davis said.

The statement also included a link to its district performance data tables.

The 10 of 28 elementary schools in Henry County that posted the highest percentage of students in third-grade English language arts on the 2018 tests are:

Timber Ridge Elementary School: 50 percent proficient; up 76.7 from 2017
