Why are digital PSAT/NMSQT and PSAT 8/9 being offered in the U.S. before the SAT?

The PSAT/NMSQT and PSAT 8/9 are being offered digitally in fall 2023 so that students who will be taking the SAT as juniors in the spring of 2024 have an opportunity to familiarize themselves with the digital testing experience before taking the digital SAT.
