Challenging the conventional wisdom on teacher certification

Teacher certification isn't all it's cracked up to be, economist Byron Schlomach writes in a new report ("The Need to Review and Reform Occupational Licensing in Oklahoma"). 

"Many studies of teacher certification/licensing have been done that show little to no support for the notion that teacher certification/ licensing regimes improve student outcomes over having teachers that are simply well-acquainted with the subject matter that they teach," he writes.
