The billable hour destroys innovation, it doesn't capture value, it is
a terrible measure of performance, and causes tension between clients and lawyers.
But not for all the usual reasons that people raise concerns: the worry about whether we've got good
measures of teacher
performance, especially for instructors in subjects other than reading and math; the likelihood that tying achievement to evaluations will spur teaching to the test in ways that warp instruction and curriculum; the futility
of trying to «principal - proof» our schools by forcing formulaic, one - size - fits - all evaluation models upon all K — 12 campuses; the
terrible timing
of introducing new evaluation systems at the same time that educators are working to implement the Common Core.
