I think you are mistaken about the relevance of high school. For a lot of people, high school was a traumatic and/or violent experience that they would rather forget. Does making high school "suddenly relevant" put up an artificial barrier-to-entry for candidates that were able to overcome bad experiences in high school and move on to something better? What about candidates who say something like "high school was awful and I got out as quickly as I could"? Maybe you have a bias in hiring toward candidates who are good at "making stuff up that sounds good"?
