The Anniston public school system saw its scores improve on annual report cards released Friday by the Alabama Department of Education.

Anniston City Schools earned a “C” for the 2017-2018 school year in the state rankings, which reflect the measurement of schools by a variety of indicators, including graduation rates and testing data. In last year's results, the school system received a “D.”

Anniston's improvement fits with the trend across the state, with many school systems moving up from “D” and “F” ratings.

"It is a testament to the dedication of our teachers, principals, and all those who support their work that student performance continues to rise," state schools superintendent Eric Mackey was quoted as saying in a press release Friday.

Attempts to reach Anniston Superintendent Darren Douthitt were not immediately successful Saturday. Douthitt earlier this month announced his resignation as superintendent, effective at the end of January.

Other school systems in the county — Calhoun County, Jacksonville, Piedmont and Oxford — received “B” grades, the same rank each achieved in last year's results.

School leaders have often criticized systemwide grades, saying they offer too simplistic a view of a system’s status and challenges.

The state first released grades last year, complying with a 2012 law that requires the A-F grades. Under another bill, the 2013 Alabama Accountability Act, the state's lowest-scoring schools are labeled as "failing," and their students' parents eligible for tax credits if they switch to private schools.
