One of my nieces graduated early. It made perfect sense. She was heading to a lengthy grad program; she had a full time job lined up for January-August (between her December graduation, cutting off a semester’s worth of tuition and her August start of grad school); she was moving to another part of the country so spending 8 months living at home with no rent was appealing. And since she had already been admitted to grad school, knowing more professors/better professors wasn’t a concern (she meets some of them now at academic conferences).
But the plan only came together after her grad school applications were done. Not everyone can get things together early enough to be able to “do without” all or a part of senior year. And she had done a gap year before college so was already a little older/more together than some of her classmates who were scurrying around in April of Senior year asking “Who knows how to write a resume?”
I’m not anti-graduating early. I just don’t think it’s a one size fits all solution, especially for a kid who isn’t ready to launch a year early!!!
