On the Stability (or not) of Being Irreplaceable
This is just a quick note with a few pictures in response to the TNTP “Irreplaceables” report that came out a few weeks back – a report that is utterly ridiculous at many levels (especially this graph!)… but due to the storm I just didn’t get a chance address it. But let’s just entertain for the moment the premise that teachers who achieve a value-added rating in the top 20% in a given year are… just plain freakin’ awesome…. and that districts should take whatever steps they can to focus on retaining this specific momentary slice of teachers. At the same time, districts might not want concern themselves with all of those other teachers that range only from okay… all the way down to those that simply stink!
The TNTP report focuses on teachers who were in the top 14% in Washington DC based on aggregate IMPACT
