When guidance changes, families should be able to see it.
We create a dated public record for every content version listed below. It lets families and professionals confirm that the guidance they receive matches the version we published.
Why we publish these records
Guidance can change when new research or updated professional recommendations become available. A public record shows which version existed at a specific time and whether the content has changed since.
How the record works
We give the published guidance a digital fingerprint. If the content changes, the fingerprint changes.
We add the fingerprint and the date and time to a public record.
We compare the current fingerprint with the public record. If they match, the content has not changed.
Published content records
Each record below helps confirm whether the published guidance still matches the version we recorded. More records may be added over time.
When records are available, they will appear here.
