Martha Paz left Mexico with her family when she was only a few months old. For most of her life, Paz lived in a small town outside of Dallas with her parents and younger siblings. She worked hard to get good grades in school. 

Paz has temporary protection from deportation under the Deferred Action for Childhood Arrivals (DACA) program. Now a student at the University of Texas, she is working toward a degree in management information systems. But as early as this month, the U.S. Supreme Court could issue a decision that spells the end of deferred action for Paz and hundreds of thousands of other young immigrants looking to improve their future through education.

Few things in life loom over American high school students more than college admissions tests. After years of toiling to earn good grades, years of slogging through Advanced Placement courses, and years of participating in extracurricular activities to burnish their credentials, many students take a test that they’ve been told can either catapult or crush their college hopes.

But now a movement is accelerating across the country, with more colleges giving students the choice of either submitting their SAT or ACT scores or not. It marks one of the biggest changes in college admissions in the past two decades.
