I recently began my MSN in education program. For the first several classes, the instructors' grading, comments, and expectations were for the most part very consistent. Then I started my current class. Things I've been doing for the last several semesters that were never commented on are now being done incorrectly (especially APA formatting), grading is different (much harsher, not that I expected good grades to just be handed to me if they weren't earned), and comments for why/how things are graded are non-existent (and unhelpful when they are given). My undergrad experience was that across the program, faculty were consistent except for minor differences.
Do the schools you work for expect/encourage consistency? I understand that no two instructors will ever be the same, but believe that schools should have certain standards for grading (ie, APA formatting/grammar/spelling) that all instructors should have to comply with. When I start teaching my own classes, I don't want to be the odd one out when it comes to consistency between faculty.
