Glossary

The NICE glossary provides brief definitions and explanations of terms and jargon used on our site. The terms describe how we work and how our guidance is produced.

Our glossary excludes specific clinical and medical terms although we intend to include these in the longer term. If you cannot find the term you are looking for, please email us so that we can consider adding it to the glossary.

The glossary is not used for indexing the site or for navigation - for information on this, please see the NICE taxonomy.

We still have relatively few terms in the glossary. New terms are added monthly.
