I spent thirty years as a teacher and as an administrator in the Tacoma School District and can say that teacher evaluations are not only a monumental waste of time, but an obscene waste of taxpayer dollars.
Since building principals have to continue to work with those being evaluated, they tend to greatly overstate the positive. When they do write an evaluation that might get someone dismissed, teacher union representatives are there to defend them before the ink gets dry.
If a building principal spends an average of four hours per evaluation, at $50 an-hour that comes to about $8,000, or $200 per teacher. Washington State schools employ more than 50,000 teachers.
Do the math.
