Measure research impact and quality: Journal quality & impact

Why quality matters

The need to focus on quality publications has been emphasised in the recent ERA process and changes to the RPI at Curtin University. The systems in place tend to rely on metrics and other pre-defined standards of quality, which can disadvantage some areas.
Factors to consider when determining the most appropriate journals in which to publish your research include:
  • Discipline relevance and reaching the desired target audience.
  • Journal quality or impact, often determined through use of metrics.
  • Prestige of the editorial team, contributors and journal circulation.

Impact Factor vs SJR

The Impact Factor and SCImago Journal Ranking (SJR) are two common measurements or rankings of journal quality. Both measures look at the number of citations the journal has received.
This table highlights some of the main differences and commonalities between the two measures.
