Metrics and Impact: Overview

Overview

Measures of research performance, impact and engagement may be used when applying for grants or academic promotion.

They can be measured by a variety of metrics, including:

  • how many times a publication has been cited
  • an author's category normalised citation impact (CNCI)
  • benchmarking an author's CNCI against category, national or international data
  • the top 1% or 10% most cited researchers in a category
  • the quality of the journal in which an article has been published
  • the amount of international or industry collaboration
  • how many libraries hold a copy of a book, or book sales
  • how much attention has been seen via social media
  • whether research has influenced policy.
