The aim of this call for expressions of interest is to draw up a pool of peer reviewers for Step 5 of the HR Strategy process (external evaluation). The peer reviewers will evaluate the implementation and success of the Institutional HR Strategy for Researchers developed by participating institutions, both on the basis of written material and through site visits. Each peer reviewer will evaluate up to twelve institutions, including visits of up to six institutions depending on the total number of institutions to be evaluated. The first evaluation round will take place in late 2013 and the second round in autumn 2014. The outcome of the external evaluation will determine whether the Commission will renew or withdraw the acknowledgement of the HR Strategy for Researchers of the participating organizations. The peer reviewers will be supported by Deloitte evaluators who will provide them with adequate training and tools to conduct the evaluation in a coherent, professional and effective way.
