Rating

.

.

Ohio gives public schools and districts one of six ratings based on standardized test performance, attendance and graduation rates, performance on the statistical “value-added” measure that shows how much students learn in a given year as well as whether they meet federal No Child Left Behind standards.

.

.

To make the ratings easier to understand, we have translated the formal ratings into letter grades. However, the state does not officially award schools letter grades.

Performance Index

.

.

This measure reflects the achievement of every student, not just those who score proficient or higher. Districts, buildings and charter schools earn points based on how well each student does on all tested subjects in grades 3-8 and the 10th-grade Ohio Graduation Tests.

.

.

All tests have five performance levels – advanced, accelerated, proficient, basic and limited. The percentage of students scoring at each performance level is calculated and then multiplied by a certain value assigned to that performance level. The multipliers for higher performance levels are larger than those for lower performance levels.

Value-Added

.

.

Valued-added is a statistical measure that reflects whether students are making a full year of progress in a year of school, regardless of their levels at the start of the year. It applies only to reading and math in grades 4-8. Above” means that students in the district showed more than a year’s worth of academic achievement last year. “Below” means students showed less than a year’s worth of achievement, and “Met” means they showed one year of progress.

% Low-Income

.

This shows the percentage of students who are low-income, defined as being eligible for free or reduced-price lunch, living in a household where a resident is eligible for free or reduced-price lunch, or receiving public assistance. A student is eligible for reduced-price lunch when household income is below 185% of the federal poverty level, meaning less than about $ 41,000 for a family of four.
