Cognitive Adaptability
The exact item set behind the neuroplasticity assessment, published for audit. Every credential issued for this test is stamped with the content hash below; verify a credential to see the stamp checked live.
Public today — may be locked up at any time. These batteries are published so anyone can inspect the exact questions behind a testmyself credential. Publication is at our discretion: the batteries are public today, and we may lock them up — make them private — at any time, without notice. Locking them up would not change any credential already issued: every credential stays pinned to the battery version and content hash recorded when it was scored.
The content pin covers the full battery data, including the answer keys. The keys themselves are never published — scoring stays server-side. What is shown below is every item’s public content, exactly as candidates see it (per-item fields the server strips before serving are the keyed fields only).
