The state says nearly nine of 10 Ohio third-graders met new reading targets and can move onto the fourth grade after follow-up testing.
Students can be held back if they don't meet the literacy goals under the state's new Third Grade Reading Guarantee.
The Department of Education said Tuesday more than 110,000 third-graders or 88 percent of the total have earned the necessary score in testing in October or May.
The figures are up from the 63 percent who passed in October.
Officials say students lacking the standards may have already been re-tested by districts or can re-take reading in the summer.
Children still lagging this fall could advance to fourth grade midyear once the targets are met.
