We have preceptors complete evals on each student, and in turn each student evaluates their preceptor... I go with the old "If I don't know it's broken, I can't fix it attitude".. more often than not, the preceptors really don't spend any time with the form.. they circle all 5's or whatever, and then send it on to me... I have very few who give honest critiques...the student on the other hand are often too happy to give feedback on the preceptor.. there's some food for thought.. Those of you who are Preceptors remember, ALWAYS give honest feedback on student evals.
Just my 2 cents.
