Overview
This annex provides a summary of all the additional information statements relating to outputs that are required in submissions. It should be read alongside, and does not replace, the details provided in the Guidance and in the relevant parts of the Panel criteria, as indicated in sub-section 9. It is intended for institutions’ ease of reference in identifying the requirements for additional types of information about outputs, across the four main panels.
The word limits for the additional information about outputs are common across the four main panels, as set below.
Outputs that include significant material published prior to 1 January 2021 and submitted to REF 2021
Maximum 100 words.
Panel requirements for all main panels: 100-word statement on how far the earlier work was revised to incorporate new material
- Reference: paragraph 3.0.2., Section 6: Assessment criteria – CKU in the Panel criteria
The researcher’s contribution to a co-authored or co-produced output
Maximum 100 words.
Main Panel A requirements: affirmation of the researcher’s contribution to the output (selected from the statements provided) only where the research upon whom the substantive link is based is not the lead or corresponding author and the output has more than 50 co-authors, or the research upon whom the identified substantive link is based is part of a consortium or group in the authorship listing.
- Reference: sub-section 4.,Section 6: Assessment criteria – CKU in the Panel criteria
Main Panel B requirements:
- UoAs 7, 11 and 12: none
- UoAs 8, 9 and 10: affirmation of the researcher’s contribution to the output (selected from the statements provided) only where the researcher upon whom the substantive link is based is not the lead or corresponding author and the output has more than 50 co-authors.

- Reference: sub-section 4.,Section 6: Assessment criteria – CKU in the Panel criteria
Request to double-weight an output
Maximum 100 words.
Panel requirements for all main panels: a supporting statement to justify the request.

- Reference: sub-section 16., Section 4: CKU guidance in the Guidance and paragraphs 8.0.4. to 8.0.8., Section 6: Assessment criteria – CKU in the Panel criteria
Information about the research dimensions and research contribution
Maximum 300 words.
Main Panel A requirements: statement for any output where the role of the researcher, or research process, is not evident within the output (for any output type).
- Reference: sub-section 8.1., Section 6: Assessment criteria – CKU in the Panel criteria

No sub-panel will routinely consider requests to submit outputs under the long-form exception.

Main Panel C requirements: all sub-panels will consider requests under the extended process following the relevant guidance in the Panel criteria. No panel will routinely consider requests to submit outputs under the long-form exception unless the criteria for extended process are met. All sub-panels will accept outputs submitted under the guidance on substantive links that ended up to five years before the output was first made publicly available, only on the same terms as those set out above in relation to requests for a pre-publication exception.
