john is the only one of the beta kids whos ever been to school
roses house is over an hour away from the closest middle school. obviously shes homeschooled. for most of her youth mom would invite live-in tutors for her, up until rose realized she could torment them and drive them away… and by that point rose was doing schoolwork far above her grade level and more than capable of keeping up with her studies without a guide, so mom just gave up on the whole thing. she does try to personally tutor rose in her specialties sometimes - computers, biology, astronomy - but rose doesnt really take to them. she knows more about any of them than youd expect a 13-year-old to regardless.
dave doesnt exist as far as the us government is concerned. bro scooped him up out of the crater in 1995 and took him straight home, no birth certificate, no fuss. how are you supposed to explain asteroid babies to the government, anyway? (dad and mom legally adopted john and rose, registered as discarded infants and given all the rights of us citizenship. which is the responsible thing to do, but bro finds it unnecessary and more trouble than its worth. theres a drawer somewhere in the strider household full of forged social security cards.) which isnt to say he hasnt gotten an education, just that hes gotten one entirely under bros authority - whatever that entails.
jade isnt a citizen of any country on earth and studies nuclear physics at a college level on her island in the middle of the pacific
