Certified Professional Secretary / Certfied Administrative Professional exams?

Hi, I am trying to find information on the Certified Professional Secretary and Certified Administrative Professional exams.

Thomas Edison State College's 2001-2002 Undergraduate Prospectus says the CPS certification is worth up to 33 credits with them, and since it would help me in other ways, I am thinking about taking this test.

Certified Administrative Professional is apparently an additional certfication you can get for taking a fourth test after receiving the CPS. While TESC does not list its credit equivalency anywhere I have found, I am sure it could at least be used for documentation for portfolio credit.

Does anyone have any experience with these exams? I have been having a hard time finding information about them beyond what's posted (very little) to PSI's website. I am looking for websites, books, etc. with detailed test prep materials, for example, sample exams and review study materials.

If anyone can help please post here. Thanks.
