A question about Modeling school?

Im 13, turning 14 this april.. i read that if you attend modeling school, they are most likely to hook you up with a model agency. It's one of my dreams to model for clothing store or brands like roxy, young&reckless, etc. So i was wondering if thats really true?? If so, that'd be great. I'd also like to know if they have any requirements to attend a modeling cl? Thank you in advance!
