I don't have WSJ subscription, but the part that cuts off right before the paywall says they are creating their own test. Maybe the hope is that they can create a test with less biases, but I have little optimism for a system that replaces two standardized and widely used tests with each school system creating their own versions as a replacement. This will make the process more complicated for all applicants and might inadvertently increase the advantage that wealthy have as now each school's test would need a different approach requiring more individualized and therefore more expensive prep.
