PHOENIX - The Arizona Department of Education released the 2014 AIMS test results Monday with letter grades for each school in the state.
Superintendent John Huppenthal said 65 percent of Arizona's schools received a letter grade of 'A' or 'B'.
The test results show 61 percent of students passed the math portion of the test, which remained the same compared to last year. Seventy-nine percent passed the reading assessment, a 1 percent increase from last year .
Tenth graders increased two percentage points in math and three percentage points in reading over last year, according to ADE. Writing scores improved by 5 percentage points to 75 percent.
ADE said 600 students are at risk of having to repeat third grade, a significant drop from 1,600 back in 2011.
The A-F letter grades are based on the weighting of student performance and academic growth from year to year, according to ADE. Additional points are awarded for high English Language Learner reclassifications, and reduction in drop out rates.
