The latest state report card for Dublin City Schools gave the district a low grade on the newest measurement.
Despite the four A's and B's on the 2012-13 state report card released late last month, Dublin City Schools earned a D on Annual Measurable Objectives under Gap Closing.
The district's administration said they see it as an opportunity to improve.
"We see some good things and see some things we'll want to improve on," Superintendent Todd Hoadley said of the latest report card.
Along with new letter grades given to districts this year is "gap closing," measured by "annual measurable objectives."
"It's replacing what we used to call AYP or 'adequate yearly progress,' " said Craig Heath, district director of data assessment and program evaluation.
AMO looks at the performance of students divided into 10 different subgroups by ethnicity, disability, economic disadvantage and language.
To improve in AMO, Heath said, the district must meet goals set by the state for the number of students performing adequate or better on math and reading tests and in graduation rates.
The district can also work to improve from the previous year, he said.
"This is going to be a pretty in-depth data analysis," Heath said. "We will take a close look ... so that those teachers and administrators at building levels can analyze this closely."
When looking at Dublin City School's performance on the similar measurement on last year's report card, Heath said results were comparable.
"There are a lot of similar things we're seeing," he said. "We'll continue to study this ... so we really understand AMO and the gap closing measure more."
As the district examines the new state measurement, it will also compare its performance to other local and similar districts around the state.
"Twenty-seven districts in Ohio got an A (on AMO)," Heath said. "Over half (of districts in the state) got D's and F's in the new calculation."
Despite the D, Dublin City Schools performed the best yet in other areas of the state report card.
On the "performance index score," Dublin earned a 107.5, up from the highest score ever of 107 last year, Heath said.
"We saw a lot (of other districts) decrease," he said. "For us to have an increase was a big step forward for us."
Although Dublin City Schools reached a personal best on performance index, which measures the number of students performing at top levels on state tests, the district earned a B.
"We missed an A by 0.4 percent," Heath said.
The "value added "measurement, which measures the progress of students over a year, also reached a high, Heath said.
For value added, Heath said, the district is trying to reach 0. Anything over 0 is more than a year's progress.
"A 16.22 value added index is ridiculously high," he said.
"Last year we were at 7.99 and we were 18th in the state out of 610 (districts)," Heath said. "We doubled this year."
When divided into three subgroups on the report card, Dublin earned B's in value added for gifted students, students with disabilities and students in the lowest 20 percent in achievement.
"When we look at specific subgroups and to have gifted, students with disabilities and the lowest performing 20 percent to all be growing at the same rate, that says a lot about our district," Heath said.
In other areas of the state report card, Dublin met 24 out of 24 state indicators, earning an A and in graduation rates the district also earned A's.
