What's school without grade levels?

HUNTER, N.D. — On windswept fields outside Fargo, North Dakota, a bold experiment in education has begun. In a lone building flanked by farmland, the Northern Cass School District is heading into year two of a three-year journey to abolish grade levels. By the fall of 2020, all Northern Cass students will plot their own academic courses to high school graduation, while sticking with same-age peers for things like gym class and field trips.

The goal is to stop tethering teaching to “seat time” — where students are grouped by age and taught at a uniform, semester pace — and instead adopt competency-based education, in which students progress through skills and concepts by demonstrating proficiency.
