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

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. 

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

Main Panel C requirements: None.

Main Panel D requirements: None, though HEIs are encouraged to use the 300-word statement to outline the author’s contribution if not evident from the output itself.

Maximum 100 words.

Panel requirements for all main panels: a supporting statement to justify the request.

Abstract for outputs in languages other than English

Maximum 300 words.

Panel requirements for all main panels: for all outputs in languages other than English, a short abstract to describe the nature and content of the work. (This requirement is waived for outputs submitted in UoA 26 (Modern Languages and Linguistics) in a language included in the sub-panel descriptor).

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).

Main Panel B requirements: statement for any output where the role of the researcher, or research process, is not evident within the output (for any output type).

Main Panel C requirements: statement for any output where the role of the researcher, or research process, is not evident within the output (for any output type).

Main Panel D requirements: statement for any output where the role of the researcher, or research process, is not evident within the output (for any output type). For translations, a 300-word statement on the role of the research or research process is encouraged along with a copy of the source text. Statement on the contribution of the attributed author to anthologies, edited books, special issues of journals and curatorial projects. Rationale for grouping short items as a single output.

Factual information about the significance of the output

Maximum 100 words.

Main Panels A, C and D requirements: none.

Main Panel B requirements:

Maximum 100 words.

Main Panel A requirements: no sub-panel will routinely consider requests under the extended process exception. No sub-panel will routinely consider requests to submit outputs under the long-form exception. 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.

Main Panel B requirements: only sub-panels 7 and 10 will consider requests under the extended process exception. No sub-panel will routinely consider requests to submit outputs under the long-form exception. 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.

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.

Main Panel D requirements: all sub-panels will consider requests under the extended process and long form exception, following the relevant guidance in the Panel criteria. 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.
