From a technical standpoint, kicking field goals in high school should not be much different than kicking field goals at the collegiate level. But like everything else, it comes with nuances and isn’t as black and white as it appears.
Logic states that the ability to kick a 45-yard field goal should be about the same, regardless of setting. If anything else, it should be easier to do so at the next level. You continue to develop physically and have access to better facilities and coaching. But that’s not always the case, as we’ve learned from Jake Pinegar as just one recent example.
