The Ohio Department of Education says today 26 percent of third-graders scored below a new literacy target on reading tests taken in the fall. Under the state's new Third Grade Reading Guarantee, students may be held back a grade if they fail to meet new reading targets. Half of the more than 21 thousand Ohio students who showed basic proficiency also will fall below what's been dubbed the "cut score" for passing third grade. Third-graders will be tested again in six months. Those who lag at year's end will have the chance to re-take reading and advance to fourth grade.
