People will continue to submit. Or rather, those that submit will be more likely chosen for acceptance. I mean, test scores, at the end of the day, help to paint a more thorough picture of a college candidate. Colleges need as much information as possible.

(Add on): Think of it like this, suppose you have two equal candidates - same GPA, same level of involvement in extracurriculars and volunteering, same quality in essays and letters of recommendation. However, one sends in decent test scores and other sends nothing. In this case, I believe the student who submitted test scores gets a better chance, solely based on the fact that the student paints a more detailed picture in the minds of the college admissions committee.

Unless Wake Forest bans the acceptance of standardized test scores, then there's no way people will stop taking and submitting scores. This will continue to happen because of the arms race that exists in the college admissions game. If one student perceives that submitting test scores will give them a leg up by painting a thorough picture of a candidate, then other students will submit in order to compete. If most students compete, then non-competing students will likely join in, simply to have a chance.

This bothers me because I wonder about how WFU, along with any future test-optional schools, will be able to fully assess a student's readiness to handle college-level classes with just grades, extracurriculars, and letters of recommendation. Grades vary from school to school, so you have to take them with a grain of salt. Other than that, there's a lack of true objectivity to aid in evaluating a candidate.
