It depends on the school you go to. The place I work at was hirring both academy and fbo cfi's you deffenitly saw that most of the fbo cfi's that took a little longer to get their ratings needed a little catching up. But Im not saying thats everybody. I think the biggest difference is that an academy cfi has surrounded themself with aviation for a couple of months and that helps. But if you are good studier then thatll do the same thing.
