Taking on teacher attrition

We once believed that teacher effectiveness dramatically increased for the first three to five years on the job and then plateaued. But recent research suggests that substantial growth in effectiveness can be seen for the first 12 years on the job, and likely longer. This suggests that teacher quality develops over time and that experience can influence effectiveness.
We also know that students who have highly effective teachers for three years in a row can score 50 percentile points higher on achievement tests than students who have less effective teachers three years in a row.

But academic gains are just one of the outcomes of high teacher effectiveness. Research showed that as teachers gained experience, their students’ absenteeism rates declined. Experienced teachers tend to be better at classroom management and motivating students, resulting in fewer conduct issues and higher attendance.

But behind the students stand a Silicon Valley technology magnate who is financing the case and an all-star cast of lawyers that includes Theodore B. Olson, the former solicitor general of the United States, who recently won the Supreme Court case that effectively overturned the state’s ban on same-sex marriage…
