In Spain, the 2017-2020 State Plan sets out the following criteria for open access:
All works published in scientific journals funded through the State Plan must be deposited in institutional and/or international open access repositories (article 37 of Act 14/2011, of 1 June, on Science, Technology and Innovation, and recommendations related to the European agenda in matters of open access and open science)
Funded R&D&I projects may optionally include a management plan for research data that will be deposited in institutional, national and/or international repositories once the project is complete and the associated funding term has passed.
All situations in which data must be protected for reasons of confidentiality, security, protection, etc., or when necessary for the commercial exploitation of the results, must be respected.
Both the researchers' curricular evaluation and the ex post evaluation of the funded actions will take into account the works published as open access in national and/or international institutional and thematic repositories, and also the availability of the research data in open access
A specific indicator is established to measure open access for scientific publications: Percentage of open access publications out of the total. The Spanish Science and Technology Foundation is in charge of monitoring this.
