Dance background for contemporary?

Ever since i was little I took Jazz Funk dance. For my last year I tried Hip Hop instead. I enjoyed both but decided to take a break in Grade 10 because I was taking a dance class in school. Ever since then I havent taken dance and dance has been my passion for all of my life. Im not graduated and was considering taking Contemporary but do you a Ballet background to take Contemporary or is it just something that would sort of help if you did. I learned a small amount of Ballet in my dance class at school but nothing compared to what a dance school would teach you. So my question is Do I need to have a history of Ballet to take Contemporary dance?
