Class Size and Educational Attainment

Here's a report on a study in Tennessee, on the effects of class size on educational attainment. It looks well-designed (random assignment of students and teachers to smaller and larger classes), and the results are somewhat different from much of the literature I'm familiar with--the authors find a fairly large, positive effect of smaller (13 - 17 student) classes, compared with larger (22 - 27). One of the conclusions:

"...the authors project that reductions in class size would generate a lifetime net cash return of almost $200,000 (presumably in the form of taxes collected) for each additional low-income student who graduates from high school as a result of early placement in a small class. "

I gotta get me a copy of that study.
