The Coalition for Evidence-Based Policy wound down its operations in the spring of 2015, and the Coalition’s leadership and core elements of the group’s work have been integrated into the Laura and John Arnold Foundation (as described
here). This website is no longer updated, but will remain available. Its key content will soon be migrated to
http://www.arnoldfoundation.org/initiative/evidence-based-policy-innovation/, and will be regularly updated on that site.
