2022 brought the largest math declines in the NAEP's history; two years later, the 2024 results show recovery stalled and reading still falling.

The online-program manager emerged from Chapter 11 in late 2024 with debt cut and owners changed; the university partnerships that made it big keep expiring.

A Stanford study found detectors flagged 61% of non-native English writers' essays as AI-generated, and a growing list of universities is dropping the tools rather than trusting the score.

Turnitin's own documentation calls its report inconclusive, and independent research finds detectors misfire most against non-native English writers and Black students.

The 'school official' exception is why a class can start using an app without a permission slip for every family — but only when a vendor clears three specific conditions written into federal regulation, not its own privacy page.

A 2007 federal practice guide gave testing-based study strategies its strongest evidence rating, but newer classroom studies show the real gains are smaller and more subject-dependent than professional-development slides suggest.

The law doesn't ban vendor access to school records. It makes the district the gatekeeper — and most of what happens next depends on a contract clause few people read.

Removing a title from a school shelf is rarely one decision. It is a process with a form, a committee, and an appeal — and 2025’s record numbers show who is actually setting it in motion.

Digital badges are pitched as a cheaper, faster alternative to a master's degree. The strongest independent study on the market found most teachers who start one never finish, and finishing didn't move student test scores.
