When I think back on all the junk I learned in high school, it’s a wonder I can think at all. That’s a slightly edited version of the Paul Simon song, which I found going through my head as I talked with a friend about high school graduation requirements. They taught us lots of stuff we really don’t use much in our daily lives. Maybe we can still speak a little Spanish or French, but I don’t remember the last time I used trigonometry or did anything with signs and cosigns. But something we do every day was something many of us weren’t taught in school. We need more formal instruction about how to handle our personal finances. Wisconsin has no requirement that high school students pass a personal finance class before graduating. Many never have any instruction on how to balance a checkbook, how interest works, the importance of a credit score, or how to file taxes. Many Wisconsin school districts offer some sort of finance course, but there is no requirement for them to do so. That should change. Students who learn the rules of the game early are likely to do better when it is their turn to play the game.
