Academy teaches basic bunshin, the ones Naruto and his classmates were suppose to perform during graduation exam. Anyway, just checked the first chapter, Naruto learns Kage Bunshin from stolen scroll, it was the first technique written there. If Naruto known Kage Bunshin in the academy then he should perform it during exam and graduate without problem. But he didn't.

Not to mention that the first meeting between Naruto and Hinata is suppose to happen before they enroll to the academy.
