SECURE Work Package (WP) 1 - State-of-the-Art on existing literature and recommendations related to research career frameworks (RCFs) is focusing on recruitment and working conditions for researchers, career development and progression for researchers, and interinstitutional (between academic institutions), intersectoral (across sectors), and international (across countries) mobility. The SECURE project aims at developing a RCF as a common researchers' career structure, recognising the diversification of careers, interinstitutional, intersectoral, and international mobility, and competences gained and needed by PhD candidates and postdocs within and outside academia. The RCF will build on existing best practices and link, as planned in the proposal, to the implementation and revision of the European Charter for Researchers and the Code of Conduct for the Recruitment of Researchers (Charter and Code)1, the revision of the European Skills/Competences, Qualifications and Occupations (ESCO)2, the new European Competence Framework for Researchers, and the upcoming Council Recommendations on a European Framework to Attract and Retain Research, Innovation, and Entrepreneurial Talents. Relevant existing literature and recommendations have been reviewed which focus on recruitment and working conditions for researchers, career development and progression for researchers, and interinstitutional, intersectoral, and international mobility. The reviews include key topics of research(er) assessment, research and transversal skills/competencies and training, research career precarity, gender equality, and Open Science. Finally, the reviews reflect on research careers in both the public and private sectors. The state-of-the-art will mainly feed into the work in: WP2 on the development of the RCF; WP3 on the development of tenure track-like (TTL) models; WP4 on the implementation and monitoring of the RCF at pilot organisations. Deliverable 1.1 - State of the Art on Research Career Frameworks has the overall objective to present the results of the literature review and provide input to the project's overall objective to "develop coordination and support measures to create, trial, implement, and mainstream a common [RCF] that offers a suite of options to support organisations in the recruitment, employment, training, development, progression, and mobility of researchers with the aim of improving research careers and reducing career precarity." The presented work will further evolve in subsequent WPs, through consultation and testing. The subsequent chapters of this deliverable are structured as follows: Chapter 2: Overall Methodology for Literature Review Chapter 3: Overall Overview on Research Career Frameworks Chapter 4: Recruitment and Working Conditions for Researchers Chapter 5: Career Development and Progression for Researchers Chapter 6: Interinstitutional, Intersectoral, and International mobility Chapter 7: Conclusions and Input to WP2/WP3/WP4 Chapter 8: Annexes - Full Bibliography
