The use of experts to evaluate tenders

The European Commission appoints independent, impartial experts to evaluate proposals and monitor projects supported by EU funding.

For example, in the context of the Horizon 2020 Programme the Commission publishes an annual list of experts (though it does not specify which experts worked on which proposals).

Experts are offered a contract that defines the rights, obligations, terms and conditions, and they are often remunerated for their services.

Code of conduct for experts

According to each call, experts may be required to sign a declaration that states that they will abide by the code of conduct for experts. An example of such a declaration is available on the Participant Portal, in Annex 1, the model contract for experts.

Who can become an expert?

Experts are employed to assist in evaluating tenders and proposals, reviewing projects and monitoring programmes or policies. In order to be selected, experts must

  • have a high level of expertise in their relevant fields
  • be available for occasional, short-term assignments
  • have good knowledge of English and French and/or German
  • be able to  use IT tools

Anyone can register their interest to become an expert, but please note that most experts selected will come from EU countries and associated countries. 

The evaluation and review work may be carried out fully or partially at expert's home or place of work, or on the Commission premises.

Conflicts of interest

Experts must declare that no conflict of interest exists and that they will inform the Commission if any such conflict should arise in the course of their duties.

If necessary, the European Commission may withdraw experts from evaluation or monitoring duties.

An example of what constitutes a conflict of interest is available in the Horizon 2020 Manual on the Participant Portal. Certain calls for experts may have different rules. It is advisable to check each particular call and its rules and conditions.

​Submitting proposals while working as an expert

For certain programmes and actions (e.g. Horizon 2020) experts may submit their own research proposals while performing evaluations as an expert - provided there is no conflict of interest. Experts will not be assigned to evaluate their own proposal or any proposals competing with it.


The European Commission may ask experts to provide records and supporting documents as evidence that the contract was carried out correctly and that any expenses claimed are genuine.
