TOP 2025: An Update to the Transparency and Openness Promotion Guidelines

Open science remains vital to the progress and functioning of the global research enterprise. Published in 2015, the Transparency and Openness Promotion Guidelines (TOP 2015) was developed as a policy framework to enhance the verifiability of empirical research claims in journal articles. It has been widely used and adopted by publishers and academic journals, but despite its uptake, concerns have been raised about aspects of the TOP 2015 framework and its implementation. In response to the above, the purpose of this manuscript is to introduce an official update to the TOP Guidelines. The final version—TOP 2025—provides updated guidelines for promoting the verifiability of published empirical research claims.
