Teachers union pushes for larger class sizes taught by bad teachers

During a special session last year, the Arizona Legislature passed a budget provision which said in the event of layoffs, school districts could not use years of service as the only factor for determining which teachers to let go. The Arizona Education Association–the teachers union–is trying to overturn the measure by filing a lawsuit on technical grounds. The union also is opposing a similar measure before the Legislature this year.

A recent Brookings Institution study reveals just how damaging the effort to protect veteran teachers could ultimately prove to Arizona students. The study tracked the value-added gains of students, after statistically controlling for a variety of factors. The bottom line finding was that some teachers are great at adding value, and some are abysmal, dragging down their students’ learning.

If Arizona schools have to follow an outdated rule that says no one who has been teaching at a school for more than three years can be laid off, then schools are forced to let the new teachers go: even if they are highly effective teachers. If you shield veteran teachers from layoffs, you shield even those who should not be in the classroom.

Such a practice is certain to lead to larger class sizes; it is also certain to put more students in the classrooms of ineffective teachers. Larger class sizes are unpopular but academically harmless, all else being equal. Systematically protecting ineffective teachers based on seniority and giving them more students, however, will be catastrophic in terms of how much those students learn.

There is more than one way to address this problem. The Legislature could, for instance, re-enact the budget provision but spell out that neither years on the job nor current salaries shall be the sole determining factor in deciding who gets laid off. The school districts should focus on measurable factors of how teachers are doing their jobs, and get rid of the bad ones first.

Teachers unions talk as if they are open minded, but behind the scenes work to kill every idea that would make schools accountable for actually teaching children. The harder the AEA pursues this agenda, the more policymakers and parents see through the facade.

  1. The fallacy that the AEA is an educational organziation is best proven by this action. They are a labor union, dedicated to the service of their dues paying members…none of which are students.

  2. Exactly. The CLIENTS of the schools are the students and parents, not the teachers and administrators. Schools are to provide a specific SERVICE: an education thru academic skills aquisition.

    It’s all backwards right now, thanks to union priorities. Restoring correct priorities will go a long ways to fixing the mess.

  3. Agreed – if the veteran teachers are effective, they can keep their jobs on their own merits. They don’t need the further advantage of tenure.

    Academic tenure is inappropriately applied to public school. The purpose is ordinarily to protect academics who might otherwise be subject to institutional coercion in their teaching and publications. This is really not an issue frequently faced in K-12 public schools.
