Call Ardrey Kell High a successful school and few who know Charlotte would argue.
Say the same about Ranson Middle School and brows may furrow.
Ardrey Kell is in south suburban Ballantyne, where strong public schools are a selling point for families with money and college ambition. It tends to top the test-score lists for Charlotte-Mecklenburg Schools.
At Ranson, in north Charlotte, most students come from low-income homes. When the state made exams tougher last year, most Ranson students failed.
