Recruitment shall be directed to securing for the institution the services of officials of the highest standard of ability, efficiency and integrity, recruited on the broadest possible geographical basis from among nationals of Member States of the Union.

Before such appropriate measures are adopted, the appointing authority of the institution concerned shall adopt general provisions for giving effect to this paragraph in accordance with Article 110.
After a three-year period starting on 1 January 2014, the Commission shall report to the European Parliament and to the Council on the implementation of the second paragraph.
In order to facilitate recruitment on the broadest possible geographical basis, the institutions shall strive to support multilingual and multicultural education for the children of their staff.
