Research/evaluation design: consent


Consent is the mechanism through which respect for participants is put into practice. This section of the Iris Ethics Knowledge Base covers the consent requirements in NS Chapter 2.2 (general requirements) and NS Chapter 2.3 (qualifying or waiving conditions), including the information participants must be given, how to present that information accessibly, withdrawal, and the circumstances in which consent may be modified, waived, or replaced with an opt-out approach.
