I think it’s the reverse. The baseline remedial student growth is say .8 grades per year. Therefore to get 1.0 grades of progress you would need 125% baseline effectiveness. To get the same with a 1.2 growth rate student it would only take 83%. Students also can’t be judged in isolation, remedial students adversely affect other students so that needs to be taken into account somehow.

I’m not saying it couldn’t be done but you would need a pretty sophisticated model to try to figure out who is or isn’t effective. Then once you turned on the model you would need to constantly tweek it to handle metrics based tampering.

Not necessary. Do end of year testing, the same as is done today for assessing achievement levels.

You have to eliminate 3rd factor issues that the instructor has no control over and that’s the complicated part of the problem
