Henry is sixteen when he starts his senior year, not seventeen. Henry was born in August 2001 and "Hyperion Heights" takes place in October 2017 (time travel, remember), so based on the events in "Is This Henry Mills?", Henry's senior year must have started in 2017 (or earlier, but that seems unlikely), the year he turned sixteen. In the US, people usually enter their senior year in high school when they are 17 or 18 years old. I am not American, but I've been told there is actually no age you must be in the US to graduate high school, all you have to do is have completed all the required courses that your school district (which includes state and federal guidelines) requires.

Of course, the markings on Regina's door indicates that Henry completed all of his twelve school years, but maybe Henry started school when he was five... Or it could simply be a prop mistake.
