Pretty Much Anyone? Part II: Pretty Much Anyone Can Use a Rubric


Many teacher evaluation systems are predicated on the belief that MTP can be carried out by pretty much anyone who is sufficiently trained in the use of an observation protocol, scoring rubric, or other measurement instrument.  Observers or raters are trained in the use of the instrument, they practice until a threshold of reliability is achieved, and then they are sent forth to use the instrument.  Questions like, “how can someone who has never taught my grade, content area, or type of student measure the quality of my instruction?” are answered with reference to the fact that, after sufficient training, raters with teaching experience and those without experience produce similar ratings.  For the moment, let’s accept this answer and move on to address ITP.
