When will colleges make decisions on new ACT section retests?

I would characterize it as many…I think it’s well over 100, but certainly not as many as superscore the SAT.

Note there is a type of hybrid policy…some schools do look at the highest subsection scores but do not formally recalculate a superscored composite. Students do enter their highest subsection scores on the common app, which makes it easy for colleges to see subsection scores.
