About Legend Standards

Teachers and families should not have to dig through PDFs and state-department pages just to understand the standards students are expected to learn. We built this site to put U.S. K-12 standards in one readable place, with the official source linked on every page.

  • Free for all
  • No account required
  • Refreshed when states change frameworks

Standards set the learning goal. Teachers turn that goal into assignments, rubrics, and feedback students can use. When the standard is unclear, the rubric drifts and the feedback drifts with it.

So we made standards easier to find, easier to understand, and easier to share with families.

What's on this site
A free, public reference for K-12 learning standards in the United States.

Every U.S. state, the District of Columbia, and the five inhabited territories, organized by subject and grade. Each entry links back to the official state document.

Plain-English explainers for the major frameworks, including Common Core, NGSS, WIDA, ISTE, CASEL, UDL, and C3. You'll also find a short library of guides for teachers, school leaders, and families.

No account required and free for anyone to use. We refresh the content when a state changes its frameworks or assessments.

How we keep it useful
A few rules we hold ourselves to.
  • Cite the official source on every page.

    You should always be able to verify what you read against the official standard document. We link the publisher on every framework and state page.

  • Plain English first, then the original.

    We translate the codes and the technical phrasing into language anyone can read in two minutes. The official text is right there underneath.

  • Standards only. Curriculum stays local.

    We tell teachers what their state has adopted and what each framework actually says. We do not pick textbooks or set pacing for any classroom.

  • Refresh when the source changes, not on a calendar.

    Frameworks turn over on multi-year cycles. We re-ingest a state when its department of education updates its document, not on a schedule that drifts away from reality.

How it connects to legend.org
The same team that builds Legend maintains this site.

Legend is the tool teachers use to turn student work into rubric-aligned feedback. Standards sit at the top of that workflow.

A teacher who picks the right standard for a unit can build a rubric that maps to it and draft feedback that uses the same language. Grades and family reports follow from the same hierarchy.

This reference stays free because it should be. Legend pays for the work; teachers pay nothing.
