“…The multi-dimensionality of education policy can be usefully captured by making reference to the two main levers that governments have at their disposal to run and reform their education systems: (de-)stratification and (de-)standardisation (cf. Allmendinger, 1989;Giudici et al, 2022). Seminal work by Allmendinger (1989, p. 233) defines stratification as 'the proportion of a cohort that attains the maximum number of school years provided by the educational system, coupled with the degree of differentiation within given educational levels (tracking)' and standardisation as 'the degree to which the quality of education meets the same standards nationwide' measured by variables 'such as teachers' training, school budgets, curricula, and the uniformity of school-leaving examinations'.…”
