Hi I searched online but I can't seem to get a definitive answer. Clinical hours for Lpn schools
seem to vary from 300 hours to 1000.
I wouldn't think that low hours should affect your Nclex-pn scores very much. The tests are generally all from the books. Definitely ask the instructors though, or the school director if they are satisfying the state board requirements for licensure. I don't know what state you're in, but your state board of practical nurses should also have a website that describes the requirements, including number of clinical hours.
Generally if these aren't met they will not allow you to sit for the boards.
oh! Also I just re-read your post and I see they were starting clinicals but the site is asking them not to come during inspection. This happens a lot. In general the school will supply alternate clinical "type" activities, like watching videos or something, until the inspection is done... Usually one week. That's ok too.
