The New Teacher Project (TNTP) has a new, highly-publicized report about what it calls “irreplaceables,” a catchy term that is supposed to describe those teachers who are “so successful they are nearly impossible to replace.” The report’s primary conclusion is that these “irreplaceable” teachers often leave the profession voluntarily, and TNTP offers several recommendations for how to improve this.
I’m not going to discuss this report fully. It shines a light on teacher retention, which is a good thing. Its primary purpose is to promulgate the conceptual argument that not all teacher turnover is created equal – i.e., that it depends on whether “good” or “bad” teachers are leaving (see here for a strong analysis on this topic). The report’s recommendations are standard fare – improve working conditions, tailor pay to “performance” (see here for a review of evidence on incentives and retention), etc. Many are widely-supported, while others are more controversial. All of them merit discussion.
I just want to make one quick (and, in many respects, semantic) point about the manner in which TNTP identifies high-performing teachers, as I think it illustrates larger issues. In my view, the term “irreplaceable” doesn’t apply, and I think it would have been a better analysis without it. Read More »
The New Teacher Project (TNTP) just released a “fact sheet” on value-added (VA) analysis. I’m all for efforts to clarify complex topics such as VA, and, without question, there is a great deal of misinformation floating around on this subject, both “pro-” and “anti-.”
The fact sheet presents five sets of “myths and facts.” Three of the “myths” seem somewhat unnecessary: that there’s no research behind VA; that teachers will be evaluated based solely on test scores; and that VA is useless because it’s not perfect. Almost nobody believes or makes these arguments (at least in my experience). But I guess it never hurts to clarify.
In contrast, the other two are very common arguments, but they are not myths. They are serious issues with concrete policy implications. If there are any myths, they’re in the “facts” column.

In a previous post about seniority-based layoffs, I argued that, although seniority may not be the optimal primary factor upon which to base layoff decisions, we do not yet have an acceptable alternative in most places—one that would permit the “quality-based” layoffs that we often hear mentioned. In short, I am completely receptive to other layoff criteria, but insofar as new teacher evaluation systems are still in the design phase in most places, states and districts might want to think twice before chucking a longstanding criterion that has (at least some) evidence of validity before they have a workable replacement.
The New Teacher Project (TNTP) recently released a short policy brief outlining a proposed alternative. Let’s take a quick look at what they have to offer. Read More »
