RALEIGH, N.C. — North Carolina schools post an average score, nationwide, in an annual report card released Wednesday.

Editorial Projects In Education's "Quality Counts at 10" report gives the state's school system an overall grade of C+, but the state scored above average in two of the four graded categories and just below average in one category.

The report concluded that the state does well in the category of standards and accountability, scoring a B, because of its measures and assistance it gives to low-performing schools.

The state's teaching standards and accountability for teacher quality also earned the school system a B in efforts to improve teacher quality.

But the report also ranks North Carolina with a C- in the category of resource equity, putting it as one of the worst school systems in the nation when measuring the gap between rich and poor counties.
