This book analyses the current trends, developments and challenges involved in the implementation of new academic career models across European higher education, providing a multifaceted reflection on the future trajectory of universities. Due to the global nature of academic work and the high level of mobility between different systems, ideas are easily transferred across countries, cultures and contexts. However, this book finds that the implementation of these ideas often proves challenging because tenure tracks are strongly dependent on their respective national academic traditions and administrative cultures. The international range of expert authors in this edited book adopt a comparative approach, contrasting ten empirical country case studies across Europe with US models. In doing so, they develop an overall framework and vocabulary for analysing the nuanced meanings, ranges and levels of academic careers and tenure tracks. Outlining how the different tenure-track systems in European universities exemplify the changing landscape of higher education policy and practise, this book will be a vital resource for students, scholars and those working across higher education management, administration and policy.
