There's tremendous opportunity on the horizon in America's classrooms, with half of our teachers ready to retire over the next decade. Filling their shoes will be challenging, since 9 of 10 top-tier students don't view teaching as a desirable profession. The potential shortfall could hinder our ability to lead the global economy. The human costs could also be enormous, since research shows that students with top teachers earn an average of $50,000 more than their peers over the course of their lifetimes. America urgently needs a pipeline of engaged, energized students who want to teach, particularly African Americans and Hispanics who make up 40% of today's K-12 students. The teacher recruitment PSAs make a compelling case for teaching as an innovative, fulfilling career for those who want to make more of their lives.
