At the university, I get evaluated by my students at the end of each semester. They fill out an online survey the last week of classes which goes to the provost.
I also get evaluated at the end of each school year by the dean. This is based on a yearly report I have to complete on curriculum development, service to the college, professional development, etc. – plus classroom observations by the dean.
Every four years, they also review your metrics to see how many students sign up for your classes, your pass/fail rate, student persistence rates, etc.
