ORLANDO, Fla. -

Fewer third-graders have passed the tougher new Florida Comprehensive Assessment Test's reading and math exams, just as predicted.

Results released Thursday show that 56 percent are reading and 58 percent are doing math at or above level three on a one-to-five scale. Third-graders, though, need only score at level two or above on the reading exam to be promoted. Only 18 percent, or nearly 36,500 students, didn't make it.

In Orange County the score moved less, from 76 percent to the same 58 percent as state average, according to a release.

Thirty-one schools in Orange County still equal or exceed last year’s district average of 70 percent, scoring at Level 3 or above, in reading. Ten of those chalked up proficiency scores higher than 80 percent.

The top three elementary schools in reading are Princeton (89%), Stone Lakes (86%) and Palm Lake (85%). Princeton improved 13 percentage points over last year. Stone Lakes went up three points.

The school to make the greatest gain in Reading proficiency over last year was Eccleston Elementary, where scores jumped 15 percentage points.

In math, Avalon Elementary third graders scored the highest in Orange County, with 91 percent proficiency. Stone Lakes registered at 86 percent and Windermere came in at 85 percent scoring at Level 3 or above. Fourteen schools were at 80 percent or better.

Three Points Elementary was the most improved performer with an eight percentage point increase in math scores, compared to last year.

Orange County’s 56 percent proficiency in reading beats out comparable districts including Dade (53), Duval (51), Palm Beach (54), Osceola (54), and Polk (48).

In math, Orange County ranked 58 percent proficiency-ahead of Duval (56), Hillsborough (55), Lake (56), Osceola (49), Palm Beach (56), Polk (53) and Volusia (56).

Students last year took the FCAT 2.0 for the first time, but scores then were based on a previous grading system. As a result, 72 percent passed the reading test and 78 percent passed the math exam.

The 2011 tests now have been rescored using the new grading system, and the results are nearly the same as this year.
