Adjusting evaluation weighting

Adapting the weighting of evaluation criteria in an assessment can be used to better reflect the goals of what should be supported and the priorities of the evaluating body.

WarningObjectives and potential outcome

Weights of diverse elements may be used to calibrate an assessment towards the elements that are most important. This method can be used to promote specific assets and characteristics of assessments.
- More pronounced focus on elements that are agreed to be of importance
- Greater transparency in the evaluation process by allowing candidates to better understand how the assessment is performed.

Research domains

Weightings in assessment models can be applied to any assessment with a comparative aspect. It is easier to implement where scoring is taking place, but it may also be relevant to highlight elements that are most important in a fully qualitative assessment.

Context and considerations

This process is especially relevant for funding applications. Many funding organisations attribute weightings to specific sections of grant applications, thereby identifying to applicants which sections have more impact on the final scoring of their application.

Weightings is also used in systems evaluations and scoring, for example the UK Research Excellence Framework, which uses weights to highlight how much each category of submissions (Strategy, people and research environment; Contribution to knowledge and understanding; Engagement and impact) is worth in the final scoring of the higher education institution. Similar calculations are used in rankings or country-level R&I comparisions.

While weightings can also be used at individual evaluation level, for example in hiring and promotion, care must then be taken to consider potential impacts of the weighting processes on the selection process (e.g., does it reduce the diversity of candidates, does it create a uniform view of ‘a good researcher’, does it influence practices, etc.).

Challenges and mitigations

Challenge: Weightings provide applicants an indication of what matters most to the evaluatiors. In this regard, they may influence practices, discourage diversity in the pool of applicants, and influence how much worth applicants and researchers place on specific aspects of their work.
Mitigation: Carefully thinking about the possible influence that weights may have in the long term is crucial for responsible assessment. This may include an Equality Impact Assessment and additional analyses to capture possible unintended consequences and gaming that may be generated by the weights imposed.

Challenge: If weights are only known by a subgroup of applicants (e.g., those with connections as assessors), inequalities and unfairness may ensue.
Mitigation: Making sure weighting and assessment criteria are transparent and accessible to all applicants may help promote fair assessment processes.

Evaluating success

Weighting and changing assessment criteria may have impacts on research practices in the long term. Assessments of success should consider longitudinal studies of impact.

Case examples and literature

Many different funding agencies use weighted scoring in their assessment criteria.

An example from the UK Space Agency NSIP programme in Annex C of the Call for proposals: National Space Innovation Programme - International shows how they distribute the weightings between Innovation, Relevance of innovation proposed, Benefit to the UK, and Sound management and planning, with each criteria explicitly detailed and described.

Similarly, Wellcome UK shows how they use weightings in assessing fellowship proposals, distributing weights between skills and experience (25%), project (50%), and proposed plan to foster a positive and inclusive Research Environment (25%) (see here) At Wellcome, the types of elements included in the weightings and the weighting levels differ among the grant programmes to take into consideration the ultimate objective of the grant programmes (see for example how different criteria are weighted in the Mental Health Award).
