"Of course, test scores are just one piece of data colleges turn to when predicting which students are likely to excel in rigorous courses, enrich campus life with a unique perspective, graduate in four years, or even help balance the books with a large tuition check. But the hole left by the SAT and ACT means more colleges will likely be looking for new ways to help sort out who gets their scarce slots.
Enter the algorithms." …

The CSUs probably already did admissions by computer to calculate each student’s eligibility index and then rank them into buckets by campus and major (with whatever preferences there are for state and local residency).
Since they are going SAT/ACT blind this coming admission cycle, they just need to program the computer to use just the recalculated HS GPA that is the other part of the eligibility index. Of course, maybe they won’t even have to do that; if they just set each applicant’s test score to 0 in the existing algorithm, then the eligibility index will be based only on HS GPA.
Schools were already using admission software with algorithms.
