Nurse practitioner schools are schools which admit practicing nurses to further their education in their line of profession. These schools are registered with the relevant bodies which are responsible for higher education in any country. Thus if you are a practicing nurse and you are probably interested in gaining entry into a nurse practitioner school then what you need to do first before you start sending your applications to the schools is to check with the relevant bodies to find schools which are registered with these bodies. This is because if you are not careful then you might find yourself wasting your time and money in an institution which is not recognized. Basically at the end of your stay in such a school you will get a certificate which is just a paper. This paper will never help you in any way as it lacks the recognition which is required.
