The Guidelines for Transparency and Openness Promotion (TOP) in Journal Policies and Practices provide standards that reward researchers for engaging in open practices, describe what openness means across the scientific process so that research can be reproduced and evaluated, and address the values of preregistration.
The guidelines discuss eight categories of transparency standards:
analytic methods (code) transparency
research materials transparency
design and analysis transparency
preregistration of studies
preregistration of analysis plans
In addition, each category has three levels of transparency (from milder to stronger standards), allowing adopting journals to select a transparency level that what works best for authors and researchers.
The guidelines are modular so they can be adopted singly or collectively. Template text is provided for each transparency level in each category, and the appendix provides a full-text template for each level.
