Modify School Performance Grades.

HB 488 modifies North Carolina's school grading system to separate achievement (current student performance) and growth (improvement over time) scores for all schools. It requires the State Board of Education to assign distinct letter grades (A-F) for both achievement and growth using specific scoring scales (e.g., 85+ for an A in achievement, 90+ for an A in growth). Schools must display both grades prominently on their websites, and parents of students at schools earning a D or F in either category receive written notice. The overall school performance grade combines achievement (80%) and growth (20%) scores on a 100-point scale. This bill directly affects all public schools in North Carolina and their reporting requirements.
