The selection process is made up of three consecutive phases:

  • Phase 1 - Eligibility

    All applications are reviewed provided they meet the eligibility requirements described in the programme guidelines.

  • Phase 2 - Preselection

    • Excellence of the CV (50 %): the professional CV will be evaluated in line with the stage of the candidate's career. The relevance and contributions made by the candidate in articles published in scientific journals (citations, impact indexes,...), books or chapters in scientific and technical books, papers presented at conferences, patents granted or licensed and, in general, any other contribution that helps to evaluate different aspects of the research will be taken into account.

    • Motivation and Research Proposal (35 %): the originality, innovation and potential impact of the proposed project will be evaluated, as well as the appropriateness of the research centre and/or line of research chosen.

    • Reference letters (15 %): letters of recommendation supporting the application will be evaluated taking into account the specificity of their content with respect to the candidate, as well as the profile of the people recommending the candidate.

  • Phase 3 - Selection interviews

    • Academic and professional career (50 %): contributions made to the field chosen for the research project presented will be evaluated, as well as the coherence of the candidate's academic background and CV.

    • Candidate's potential (30 %): the candidate's potential will be evaluated, paying particular attention to multidimensional skills such as their clarity and consistency of speech and how they express ideas, their ability to present complex reasoning, teamwork, capacity for independent reasoning, originality, entrepreneurship and leadership.

    • Motivation and impact of the proposal (20 %): the conceptual and methodological innovation of the proposal presented will be evaluated, as well as its impact, understood in the broadest sense. For instance, the capacity of the project submitted to contribute towards transformation and improvement, in areas such as the economy and creation of wealth, society, culture, science, quality of life of citizens, environment or public policies.


Each year, the Fellowship Programme benefits from the collaboration of a large number of experts from different disciplines who are involved in evaluating applications to ensure rigour and transparency in the selection process.

Download materials

With the aim of creating synergies and informing as many people as possible about the Postdoctoral Junior Leader fellowships call for applications, we'd be grateful if you could help us disseminate the communication materials among the students and young researchers.

More information

  • How should the communication materials be disseminated?

    To ensure effective communication, first of all we'd recommend a mailing to explain the details of the call to the students and researchers.

    Then we'd suggest publishing the downloadable posts about the call on all social media channels, taking into account the texts proposed for publications contained in the Recommendations for promoting the call on Social Media.

    We'd also recommend printing the posters in A4 or A3 format to publicise the call at the university or centre.

    ”la Caixa” Foundation is very grateful for your help in promoting calls among the students and researchers. To optimise the communication materials, we'd like you to help, as far as possible, by providing us with some important data on the pieces published on your digital channels: a description of the audience reached, screenshots of your publications on social media and the language in which your posts were published.
