Do ACT scores expire?

Hi! With Covid, it doesn’t seem like I’ll be able to retake the ACT, but now I’m wondering if retaking is actually necessary-
I’m a rising senior and have taken the ACT twice (2016, 2018). If I super score with just my reading score from 2016 and the rest from 2018, then I’m happy with my overall score. Is this valid to colleges or not (since the first test was when I was a 7th grader…). Thank you!

A handful of colleges specifically require scores from junior or senior year, but I can’t imagine anyone being too picky under the circumstances. If you are happy with your score, submit it.
