MSN CNS or CNL??

There is a big difference. A CNS (clinical nurse specialist) is an advanced practice nurse specializing in a specific clinical specialty. A CNL (clinical nurse leader) is Master's prepared, but not an advanced practice role. The CNL is a Master's-prepared generalist bedside nurse with extra education to prepare her/him to coordinate and manage care and provide leadership to the staff nurses. The role is new and somewhat controversial. It's not clear how much demand there is going to be for the CNL. There are a bunch of existing threads here about the CNS and CNL roles -- you could use the "search" button in the upper right corner of the screen to find them. Lots of good info and discussion.
