On June 27-28, 2018, the U.S. National Academies of Sciences, Engineering, and Medicine (the National Academies) convened an international workshop in Amsterdam, the Netherlands, on developing norms for the provision of laboratories in low-resource contexts. The U.S. Department of State's Biosecurity Engagement Program requested that the National Academies organize this workshop to engage an international group of organizations that provide funding for construction, upgrades, and maintenance of biological laboratories in countries without the means to build such labs themselves. Twenty-one people from 19 organizations participated. The intent was to advance the conversation about the identification and application of guiding principles and common norms for use by these organizations in their grants, partnerships, and aid. This publication summarizes the presentations and discussions from the workshop.
