Spoiling the bunch
Eric Hanushek at Hoover Digest on teachers' unions:
"My research—which has focused on teacher quality as measured by what students learn with different teachers—indicates that a small proportion of teachers at the bottom are dragging down our schools. The typical teacher is both hardworking and effective. But if we could replace the bottom 5–10 percent with an average teacher—not even a superstar—we could dramatically improve student achievement. The United States could move from below average in international comparisons to near the top."
