The Transparency and Openness Promotion Guidelines are a community-driven effort to align scientific ideals with practices.

Transparency, open sharing, and reproducibility are core values of science, but not always part of daily practice. Journals, funders, and scholarly societies can increase reproducibility of research by adopting the Transparency and Openness Promotion (TOP) Guidelines and helping them evolve to meet the needs of researchers and publishers while pursuing the most transparent practices.


Published in Science in 2015, the TOP guidelines include eight modular standards, each with three levels of increasing stringency. Journals select which of the eight transparency standards they wish to adopt for their journal, and select a level of implementation for each standard. These features provide flexibility for adoption depending on disciplinary variation, but simultaneously establish community standards.

Implementing the TOP Guidelines

  • Compare your current author or grantee guidelines to the three levels of each of the eight standards in the TOP Guidelines. Email top@cos.io for support or feedback on this evaluation.
  • Review the language on these sample implementations for journals or funding agencies.
  • Determine which standards you wish to improve on and discuss the changes that would be required to implement Level I, II, or III for each standard.
  • Update your journal policies and practices and plan a strategy to implement. Consider using a piloting period, special issue, special RFP, or apply the standards to all incoming articles.
  • Consider making an announcement about your implementation through an editorial, blog post, or other outreach.
