Lindsay Unified School District (California) exemplifies the promise of competency education (or performance-based education, as it is called locally). Since beginning its transition to the model in 2009, discipline problems have sharply dropped, the school climate has dramatically improved (as measured by the California Healthy Kids Survey), and academic achievement has slowly, but steadily, climbed. But, even boosters of competency education worry that, if poorly implemented, competency education could turn into yet another boon for the most advantaged students, leaving everyone else further behind.
