I just graduated from this program two weeks ago. To carry the title of Clinical Nurse Leader you must take the CNL certification exam which consists of 150 questions. I take mine this Friday. If you do not pass, you will still have a masters degree in the area, but not considered a CNL. The CNL is an advanced generalist. There are definitons and comparisons on the AACN website or just type in http://www.aacn.nche.edu/cnl/CNLCNSComparisonTable.pdf
A clinical nurse specialist who is an advanced practice nurse, a CNL is an advanced generalist. Go to the AACN website and go to the clinical nurse leader section. The next website is http://samples.jbpub.com/9780763776312/76312_CH01_Harris.pdf
word of advise...if you live in the Midwest look at the state directory for CNL s. My state only has 22 and a good portion of those are educators who have taken the test to teach. If you are on the east or west coast you are likely to find positions in the CNL field. In the Midwest they are not being used as CNL's, but as other fields such as resource nurses, coordinators, directors, risk analyst, outcomes managers etc.
A (+) note is the VA says there has to be 2 CNL s in every VA facility across the US by 2014.
