Don’t Be Afraid of Constructive Criticism
There are many administrators that go into an evaluation with no intent of marking anything other than good or excellent. There is not a teacher who exists that cannot improve in some area. Offering some constructive criticism or challenging the teacher will only improve that teacher’s ability and students in that classroom are the ones who will benefit. Try to pick out one area during each evaluation that you believe is most important for the teacher to improve. You may not necessarily down grade the teacher if they are doing a fantastic job, but let them know this is an area you see room for improvement in and most teachers will work harder to improve there. If during evaluation you see a teacher who has substantial deficiencies, then it may be necessary to put them on a plan of improvement to help them vastly improve those deficiencies.
