Clayton middle, elementary schools improve but lag state averages on report card

Clayton County schools average scores on the just-released 2017 state report card lagged the state averages, but showed improvements from last year.

The College and Career Ready Performance Index ranks schools on a 100-point scale from best to worst based on a host of measures, such as test pass rates, while also taking into account issues such as poverty rates.

The report card’s results give administrators, teachers and parents consistent, if not always well understood, yearly guideposts to measure their school’s success or failure.
