Methodology

The Learning Shelf is a directory. It does not host apps, score learning gains, or sell placement.

What gets listed

A listing is published only after a curator checks that the official web destination works, that login and child-account behavior match the page, and that the privacy labels match official materials. Payment, sponsorship, and who submitted the app do not change whether it is listed or how it is ordered.

What verification means

Verified means a named curator completed that checklist and recorded the date. It is not a certification, an endorsement by a standards body, or a claim that an app is effective.

Standards mappings name a framework, code, and label, plus who made the mapping. They are not endorsements or certifications.

Where a fact came from

  • Developer disclosed: the developer’s own materials.
  • Curator observed: a curator saw it on the public site.
  • Curator mapped: a curator assigned a taxonomy or standards label.
  • User reported: a visitor supplied it, and a curator chose to publish it.

If we do not know, the page says Not verified. It does not treat an unknown as safe or absent.

How search is ordered

The default order prefers an exact name or alias, then subject, skill, and standards matches, then words in the description. You can also sort by verification date, publication date, or name. The directory does not boost apps for payment or for who submitted them.

Freshness

Curators aim to recheck listings about every 180 days, sooner when a link breaks or a visitor files a correction. Entering that queue does not by itself republish or certify a listing.
