Need your help - trying to change school policy

I would greatly appreciate your help. After losing two more students after 5th quarter (of a 6 qtr ADN program) our class would like to put forth a proposal to lower the percentage required for remaining in the program. It would greatly help our cause if we had information from other schools of their requirements. If you could please let me know your school, city, state, and type of program (ADN, BSN, LPN, etc), the minimum gpa or percentage a student can earn before they are dropped out or what happens if a student falls below that mark for a class. THANK YOU!

ex. Seattle Central Community College, Seattle, WA, 2yr ADN, min. grade to stay in the program is 82% and if you fall below that you are dropped from the program with no option to retake a class.

Again, thank you for your input, I greatly appreciate your help. If you have additional information to add about how many students have been dropped from your program that would be great too.
