Bill Gates: Restructure teacher pay to help education budgets
From Bill Gates' speech Friday to the Council of Chief State School Officers:
Our pay structures don’t identify or reward great teaching, and they don’t support it through training or new technology. Instead we spend a lot of money on things that have little effect on teaching or learning – like seniority. It’s reasonable to suppose that teachers who have served longer are more effective – you only have to assume that skill improves over time. But the evidence says it’s not true.
This chart shows that teacher seniority has only a modest effect on student achievement over the first five years and none thereafter.
Yet, seniority is the single most expensive teacher-contract provision. The pay increases that teachers get for years of service account for 10 percent of total school expenditures. On a budget of $500 billion, that means $50 billion is paid out every year for something that has little correlation with student achievement.
