<p>My feeling about this is that you should have kept up this sort of performance in college for it to be really meaningful, or else, it’s just something you did four years ago but haven’t done anything related since. If you have nothing else to put and need to take up space, then that’s fine, put it on. But a resume has limited space and accomplishments in high school should really be dropped at some point for (hopefully) better and more recent accomplishments. If you did research in high school, that’s great, but if you haven’t done any in the four years during college, then the fact that you did research in high school is going to mean very little to future employers or grad school. If you have room for it, sure you can put it, but hopefully, you’ll have had more recent and significant research experience that you can replace it with. If it’s on a CV, then maybe you can include it because you have more room. But really, at some point, it becomes less relevant or impressive. I don’t care what you did in high school. I care what you can do now.</p>
