And each essay is seen twice by a human.

What does the AI do when it marks writing? Is it an inscrutable and unaccountable black box? If so, how can we trust it? https://substack.nomoremarking.com/p/the-black-box-of-ai-assessment25 Apr 2026 08:15 +0000at://did:plc:vyg7van5a4et3mgmoxrvya4o/app.bsky.feed.post/3mkclxgzf7b2fhttps://bsky.app/profile/daisychristo.bsky.social/post/3mkaqdquxg526Our next Comparative Judgement + AI webinar is on Monday.

About 60% of students get the middle grade. So that means a student working at the Y4 standard, and one working at the Y8 standard are both told they are at the expected standard for Year 6. https://substack.nomoremarking.com/p/why-grades-are-misleading13 Apr 2026 12:15 +0000at://did:plc:vyg7van5a4et3mgmoxrvya4o/app.bsky.feed.post/3mjetrt33ut2chttps://bsky.app/profile/daisychristo.bsky.social/post/3mjebddnv2626At the end of last term, we released our latest Year 6 writing results.
