‘Opt Out’? (Part II) It’s Going to Cost Them

A small, if vocal, movement urging parents to have their children sit out standardized exams took off this year, maturing from scattered displays of disobedience into a widespread rebuke.

I commented further.

Don’t test? Then, according to Harvard professor, and MacArthur Fellow, Raj Chetty and his colleagues, it’s going to cost your kids a lot:

“…From a purely financial perspective, high income parents should be willing to pay about $6,500/yr to get [a teacher in the 84th percentile vs. one at the 50th percentile]…Impacts on earnings are…similar in percentage terms for students from low and high income families…great teachers [as measured only by the ‘average test score gain of his or her students’] create great value…”.

In other words, for a class of 30 students, the outstanding teacher is worth almost $200,000 a year more! That’s for high income families, but remember that “…Impacts on earnings are…similar in percentage terms for students from low and high income families…”

(From “The Long-Term Impacts of Teachers: Teacher Value-Added And Student Outcomes in Adulthood”, a landmark paper, by , John N. Friedman (Harvard) and Jonah E. Rockoff.)
