For years, some people have been determined to blame teachers’ unions for all that ails public education in America. This issue has been around a long time (see here and here), but, given the tenor of the current debate, it seems to bear rehashing. According to this view, teachers unions negatively affect student achievement primarily through the mechanism of the collective bargaining agreement, or contract. These contracts are thought to include “harmful” provisions, such as seniority-based layoffs and unified salary schedules that give raises based on experience and education rather than performance.
But a fairly large proportion of public school teachers are not covered under legally-binding contracts. In fact, there are ten states in which there are no legally binding K-12 teacher contracts at all (AL, AZ, AR, GA, LA, MS, NC, SC, TX, and VA). Districts in a few of these states have entered into what are called “meet and confer” agreements about salary, benefits, and other working conditions, but administrators have the right to break these agreements at will. For all intents and purposes, these states are free of many of the alleged “negative union effects."
Here’s a simple proposition: If teacher union contracts are the problem, then we should expect to see higher achievement outcomes in the ten states where there are no binding teacher contracts.
So, let’s take a quick look at how states with no contracts compare with the states that have them.
