Freddy ... this is the material you want me to discuss?
You assess the teacher with actual observations. As a supervisor I am responsible for completing yearly reviews on each of the officers assigned to me. I cannot base this simply on the number of reports, citations, calls for service, alarms responded to, etc etc. I need to have solid personal observations and documentation. Here's how I do this: I fall in on calls the officers' are sent on; I review their reports for accuracy, grammar, etc; I watch them as they interact with the public and other officers, I give them assignments and see how they do.
I have plenty of time to check on each of my officers and it is totally random so they cannot prepare.
If you get a below standard you lose your shift preference and get whatever is left open, usually 3pm-11pm and have to work it for the year. If during that year you improve and you receive a standard evaluation then you are returned to normal selection. You also are not considered for special assignments that may come up (detective, K-9, evidence technician, etc).
If anything in the evaluation is unjust, which we have has supervisors like this, then there is an appeal process through the union to right any wrongs.
If it works for law enforcement then it will work for others as well. Are there biases? Absolutely, but I have found that 98% of the supervisors are soft when it comes to evaluations and don't want to give a bad evaluation. That 2% is what the appeal process is for.
My opinion would be that a good school administrator is worth their weight in gold. And you know that gold is a rare metal.
Sadly, my experience in schools has been that very few administrators do a good job in these type of evaluations. Some do. Some don't. Some are there just be a pain in the butt to make it look like they can find something. Others are there to help when they find weaknesses or faults.
It sounds like you have the role down as far as your duties go. It sounds like you do a good and professional job and I imagine the men under your supervision appreciate constructive criticism.
If I can. allow me to relate one story about a teacher observation. This was the worst teacher in my high school and one who was later fired - and deserved it.
As part of the process, the head Social Studies Supervisor for all of Detroit Public Schools came in to observe him teach. I knew her for many years and had worked with her on several committies and we even shared a car once on a 100 mile trip to an education conference. So there were good lines of open communication and friendship there which is always a plus.
She observed this teacher for a full 55 minute class and took exhaustive notes. After the class she presented her findings and notes to both the teacher and myself as his union representative.
Without giving you the entire 55 minute wrap up- here is a summary of what she saw
9:02 Teacher starts class two minutes late.
9:04 Teacher asks nobody in particular where Deinda is and has anyone seen her. Class does not respond.
9:05 teacher begins to take attendance but has to orally call out several names because students are not sitting in their right seats. Students argue with him asking why can't he just see them. Teacher does not reply to students inquiries.
9:08 Girl in third row takes gum out of mouth and places it under her desk. Teacher says nothing.
9:10 teacher begins to review yesterdays lesson on the end of the Civil War but gets the location of treaty signing wrong. no student in class appears to care or know of the error.
9:15 Student arrives late with no pass or reason - teacher simply goes on teaching without noticing.
9:16 student in row four takes something off the desk of student in row 5 - teacher does nothing
and this went on for many pages for all 55 minutes.
So I ask her if she could come back soon and teach a model lesson. She agrees.
A week later she comes back, I sit in, and it is one tremendous lesson as she is a terrific teacher in every respect. When the kids leave I come up to her and shake her hand and tell her how much I enjoyed her lesson and how terrific she was. She just beams and is really happy with how it all turned out.
Then I showed her my exhaustive notes on her 55 minutes.
I did the same thing to her that she did to the teacher. I emphasized every little negative thing that happened and gave little mention of the positive.
She read a portion of it , saw what had happened and said it was grossly unfair becuase it was not an accurate record of that hour. I agreed with her. But also said that is what she did the previous week to the teacher.
From there we both tried to help the teacher but truthfully he was beyond help and got fired later.
