Hi I'm also in the same boat as you but am considering going for chmberlains MSN program with nursing informatics the total credits are 36( which is a lot less than other programs) and since I did my bsn with them I get the a discount per credit for 550. They even have the certification for NI. It is all online but there is a 200 hour practicum which I think is good bcuz it shows future employers that we do have hands on experience in this field. Rather than just an online program
I recently graduated from Kaplan University with my MSN in Nursing Informatics. The program was great, they have ten week sessions with a week break in between each term. It is important to make sure that you have time to complete the readings and assignments. Finding a Preceptor was challenging but I enjoyed the Practicum experience. I wish you the best of luck!
