A Think Twice Review of:

This report analyzes statewide achievement data for school districts in Florida and purports to find that Florida's constitutional amendment limiting class size, "had little, if any, effect on cognitive and non-cognitive outcomes."
Reviewer(s) - Jeremy D. Finn, The University of Buffalo- SUNY
Finn finds that the study doesn't actually address the effect of class size reduction on student achievement and has four major flaws which, when taken together, invalidate it as an evaluation of class-size reduction.
