Excerpt from CMU referenced above:
“…while we’ve lessened our SAT subject test requirements we’re hoping there is more we can do. All told, we’re working hard to change our process in a more inclusive direction.”
Inclusiveness is a key word here as universities seek a fairer diversification of their student body. A greater, cross-sectional student body which more accurately represents income, gender and cultural differences. This greater mix is viewed, in large part, as a broadening the educational experience. While CMU does not appear to be dropping the standardized tests, it is lessening their requirements.
