I thought the next JLPT wasn't until July anyways?
They might be referring to you passing a proficiency test based on your university (if you're a student). Most colleges offer people a chance to test out of lower level language courses if they claim a familiarity with the language. If you pass a test that would prove to them that you are at a level equivalent with what you would know after a year of college language courses, then you'd be fine.
Just for reference, the first year of courses when I was back in college consisted of perhaps 100 total kanji and some pretty basic grammar (-te forms, minimal casual usage, past tense verbs & adjectives...I can't remember if potential forms are used, and I know command forms aren't...no keigo either). An easy way to check up on what you need to know is to find out what book the college uses for the first year, and look at it in the bookstore.
