Need your help - trying to change school policy

Thanks everyone for your input. I'm still looking for some solid numbers but I appreciate everyone's input. Yes, all schools are different, we're trying to make ours better. The change we're trying to implement isn't to make school "easier" its to hold teachers accountable for teaching (not just weeding out students) and to give students who may not initially test well a chance. We have to pass our med calculations test with 100%, do clinical lab check offs perfectly, attain a level 2 on ATI evaluations (two of them were given even before we had the class!) and maintain a 2.5 gpa. Losing 50% of every class isn't an efficient use of resources. Clearly there are other issues such as shortages of qualified nursing instructors but to maintain the status quo really isn't getting anyone anywhere so we're trying to at least make some suggestions. To do that we'd like to know what other schools are doing. As I said, I appreciate everyone's input! Just for the record so you all don't think I'm a whiney slacker, I'm not in danger of failing out and never have been. Thanks for your time!
