Inclusion criteria

A Learning Resource may be included in the Database if:

• It is relevant to one or more Key Concepts or EBM Stage/s
• It is available open access
• It does not duplicate an existing resource.

Duplicate resources may be considered where they are judged to be more effective than the existing ones.

Resources that are accompanied by evidence of effectiveness in systematic evaluations are given high priority.

The Editorial team decides whether to include a Resource or not.

Full details of the origin of the database, as the Critical thinking and Appraisal Resource Library, or CARL, can be found here.
