I know, but that's not a difficult thing to factor in when looking at test scores.
Test scores are without a doubt an indicator of the quality of instruction a teacher gives. To think you need a calculus teacher to evaluate the quality of instruction another calculus teacher is giving is kind of silly. What's the point of having subject matter experts if you have to hire an extra subject matter expert to evaluate your first subject matter expert across all subjects? Do we get a historian to evaluate social studies teachers? An English professor to evaluate English teachers? An artist to evaluate art teachers? It's just such an impractical suggestion IMO.
