Not another article about why.

Lots of educators already agree with the philosophy behind competency-based learning, mastery grading, and standards-referenced grading. Actually making it work in a classroom or school is where it gets surprisingly hard.

So instead of publishing another explainer, we're collecting the tricky, unexpected, logistical problems — athletic eligibility, late work, retakes, GPA translation — and the ways real educators have handled them.

The seven starting challenges come from the sideby team's own experience. Everything under "How educators have handled it" comes from practicing educators, and every story is read by a person before it's published.

sideby connects educators to learn and grow side by side. This library is one small part of that: learning AI and teaching innovation the way you'd teach it — together.
