Ethical approval is required for all research projects. Where research involves the below, full ethical approval is required by the relevant faculty ethics committee. 

• Humans 
• Data relating to humans  
• Animals 
• Human tissue (must ensure that your work complies with the Human Tissue Act 2004) 
• Materials in which people living within the last 100 years are identifiable 
• Sensitive materials 

Where research poses a low ethical risk (i.e., none of the above), researchers may undergo a shorter, expedited review process. In such cases, researchers must provide background information about their project and a clear, concise explanation why their project poses a ‘low ethical risk’. It is the responsibility of the principal investigator to decide whether the project is low risk or requires full ethical approval.
