Teachers should be paid for performance/results

Teacher-pay packages that front-load higher salaries and offer bonuses if student test scores improve or if teachers work in hard-to-staff schools is a great idea. We need to move away from a traditional pay models, which increases salaries based on seniority and advanced degrees. Tie earnings and annual bonuses to improved scores, student performance, and working in hard-to-staff schools. Most other positions in the Corporate world get rewarded for results. Why should teaching be any different?
