All three registered in the 70s, which State Superintendent of Schools John Barge equated to a C letter grade.
"I think it's fairly accurate of where we are," he said.
Barge, who is running for the Republican nomination for governor, said he wanted to release unvarnished results, even if they do show marginal improvement, because he is concerned more about students than his political future.
"We're not going to hide anything. We're going to make sure our kids are getting the best education they can," he said.
The scores from the department's College & Career-Ready Performance Index show little change from last year. The average for elementary schools rose from 74.9 to 78.5 while the middle schools rose from 73.9 to 75. The high school figure dropped 1 point from 73.0 to 72.0.
The CCRPI, which educators jokingly pronounce "grapy," is a compilation of many factors. For instance, it measures 11 factors in elementary schools and 19 in high schools. Then it breaks them down into those reflecting student achievement, the progress students are making and the gap between white students and those of other races.
The weight given to achievement has been reduced in order to give greater weight to progress. And last year's scores were recalculated in order to make the comparison.
Other changes were also made in this year's calculations, such as including end-of-course-test grades for high schools. Barge said that was the main reason that the high school average dropped.
The superintendent said parents can use the scores in deciding where they will buy a house. If they already have children in a school with disappointing scores, they can meet with teachers and counselors for suggestions on how they can help their kids surpass their classmates.
