College Board has some studies on their website:
CLEPÂ
I would cite those for determining the validity of CLEP, or whether or not they will give the same level of education as a traditional class.
There is a lot of good info in this thread:

But most of it is personal experiences of test takers. Although, several of the posters have graduate degrees and/or are educators, like cookderosa who teaches at a CC. At one point she mapped out the time it took to study for a CLEP/DSST and the actual time of study you got out of a traditional course structure. That was really helpful to me when I was writing out a plan for my former university's change in CBE policy. Kind of puts things in perspective, but I don't have the link at the moment.
I would also bring up the rise in homeschooled kids applying for college. Their studies are very similar to the self-study required for CBE, though it is different in that they have a parent or tutor to walk them through the process. If they will accept those children, a case can be made for CLEP/DSST.
One major thing that I would also recommend would be to find out what other CCs or 4-year schools in your state or area accept, as far as CBE goes. Then you can make the case that they should allow it to stay competitive. I would look at it this way as a potential student: if I can test out of some core classes that I already have a base of knowledge in, finding a school that allows me to do that, rather than sitting through a class that may lose my interest, is going to be a huge factor when I am looking for a school. There are probably some pretty good arguments you can make based on other school's policies. They may lose a little money initially, but they will probably keep me as a student for the long-haul. And like my boss always says, it's better to get some money off of a sale than none at all.
I had a lot of trouble finding good, scholarly resources for my essay/letter, so a lot of mine was based on the good it would do to the students (lower cost of attendance, a "mini" scholarship, etc.), and how it would improve the school's bottom line by drawing in more students and raising their revenue a bit.
I left my jump drive that had my essay on it at a friend's house, but I will be back that way tomorrow or the next day and can post it then. I also had some more links from this forum saved on it, and that may help as well. I sort of gave up on it after SNHU started stonewalling me, but if it helps you out then at least it all that writing would not have been for nothing. Just let me know if you would like me to post it. I'm sure there are others who can benefit from it as well.
Hope that was somewhat helpful and good luck!
