Grades

How ScanGov scores and grades a site.

How scores work

Every score is a percentage: the share of applicable standards a site meets. Each standard counts equally — none is weighted more heavily than another.

Standards are grouped into four categories:

Botability — can bots and crawlers read and index your site correctly?
Accessibility — can everyone, including people using assistive technology, use your site?
Usability — is your site easy to find, navigate, and use?
Security — does your site protect visitors and their data?

A category score is the percentage of that category's standards a site meets. The overall score is the percentage across all standards, all categories combined.

How scores roll up

Each URL on a site is scanned and scored individually. Domain-level scores are the aggregate of every scanned URL, so you can see a site's overall health at a glance. See Scans for how often scanning happens.

Sites that can't be scanned (blocked bots, DNS errors, and similar) don't get a score or grade at all, and aren't factored into any average. See Status for what counts as inaccessible.

What each grade means

Grades convert a percentage score into the standard A–F academic scale:

A (90–100) — meets nearly every standard. Little to no follow-up needed.
B (80–89) — meets most standards. A handful of gaps worth addressing.
C (70–79) — meets more standards than it misses, but has real gaps across one or more categories.
D (60–69) — misses more standards than it meets. Needs focused attention.
F (below 60) — misses most standards. Needs significant work.

There's no "E" grade — the scale intentionally jumps from D straight to F, matching the standard U.S. academic grading scale.

As a rule of thumb: an A or B means a site is in good shape and any remaining work is incremental. A D or F means a site has structural gaps worth prioritizing, not just polish.

Rankings

Rankings compare organizations using their overall scores.
