The American Association of Nurse Anesthetists, would be a good place to start. www.aana.org, I think it's .org. You will need your BSN, a GPA of 3.4 or better, a GRE score >1100, and 1-2 years of strong ICU experence. There are many schools for this , and they are on the website. There is a discussion fourm @ allnurses.com. Good Luck!!
