CIRCE firmly adheres to the principles of the European Charter for Researchers and the Code of Conduct for the Recruitment of Researchers, both of which were written by the European Commission to target researchers, employers and public and private funding providers. The two documents have since become instrumental in EU policies, making a career in research much more appealing, as well as boosting financial growth and employment in Europe.

The European Charter for Researchers is a general document that defines the role and responsibilities of researchers and their employers. The aim is to ensure that the relationship between these parties effectively builds towards a more fruitful process of generating, transferring and exchanging expertise, as well as bolstering the researcher’s professional development from the outset.

The Code of Conduct for the Recruitment of Researchers was introduced to improve recruitment by making the procedures fairer and more transparent. The researcher’s achievements will be assessed based not only on the number of publications they make, but also on broader criteria including qualifications, teaching experience, supervision, team work, knowledge transfer, management, awareness raising, etc.

In an effort to make it easier for research centres to implement the principles set out in the Charter and the Code, the European Commission issued a common procedure know as: The Human Resources Strategy for Researchers (HRS4R).

CIRCE adhered to the strategy in July 2015 to further strengthen its pledge to improve HR policies in line with the European Charter and Code, on the one hand, and create a more stimulating and favourable working environment, on the other hand. The Seal is awarded to research centres that thoroughly assess their HR practices and policies and undertake regular detailed plans to improve them.

The action plan developed by CIRCE is available for download from the link below. Please note that it is assessed and amended regularly.

In accordance with the “HR Excellence in Research Award”, the aim of this OTM-R Policy is to work in accordance with the fundamental principles of the Code of Conduct for the Recruitment of Researchers. In the following documents we outline the essential steps for the recruitment of researchers at the CIRCE Foundation, from the offer and application phase, through the evaluation and selection phase, to the selection of candidates.
