If you are a nurse in the US, you’re probably already familiarized with the ANCC (American Nurses Credentialing Center), one of the most prestigious certification boards in the country. By visiting this site, users will be able to take a look at all the certificates and specialties nurses can get, explore requirements, enroll online for any tests they might want to apply for, and even get sample questions for the tests (free) or reading material and online courses (paid).
Some of the tests are done over the internet, whereas some of them are paper and pencil, and can be sat for at a wide variety of locations throughout the US and overseas, a full list of which is available at the site. If for some reason you need to get statistical information on nurses in the US, NurseCredentialing.org will prove a very valuable resource, as it comprises documents on the topic dating back a couple of years. Unlike most professional and/or technical certification boards, which list its members on their respective sites, the ANCC charges a fee for verification, which has to be snail-mailed to the association. However, by paying a fee users can choose to create a rather sophisticated online portfolio which works as an in-depth multimedia CV where certifications and licenses can be displayed.
