letter of intent

i just received a letter saying i got accepted in the nursing program and i need to write a letter of intent. How do you even start it.is it like an essay?i was not given any guidelines.help!!!!please can somebody help me?
I would just write a short letter basically accepting your placement in the program. Something like....Dear (whoever),I am writing in response to your letter concerning my acceptance into your nursing program for the spring of 2009. I gratefully accept this position.I appreciate the opportunity to begin studies to become a (LPN, RN). {spelled out though} Please accept this letter as my intent to begin your program on (date). Thank you.............I think this is all that is needed. You have already been accepted so I don't think an essay of any sort is needed...just an acknowledgment of your acceptance and an indication that you in fact intend to actually enroll. Congratulations!! Quidam

The programs that I applied to sent a form for the applicant to sign and send back by a certain date to accept their spot. The example given by Quidam sounds very good to me. Good luck in your program.

Hey Guys, just attended a nursing workshop and they requested that i write a letter of intent.In my case, i have not been accepted either....ANYONE...please advise.
