Principles of Transparency and Best Practice in Scholarly Publishing
The green tick ("The Tick") is displayed against all journals that were accepted into DOAJ after March 2014 when DOAJ launched its new criteria for journals to be accepted into DOAJ. The new criteria require a higher level of compliance to best practices and publishing standards. Journals that do not have The Tick are in the process of reapplying under the new criteria.
