Journal policies can be evaluated based on the degree to which they comply with the TOP Guidelines. This TOP Factor is a metric that reports the steps that a journal is taking to implement open science practices, practices that are based on the core principles of the scientific community. It is an alternative way to assess journal qualities, and is an improvement over traditional metrics that measure mean citation rates. The TOP Factor is transparent (see underlying data and the evaluation rubric) and will be responsive to community feedback.
