„Providing multiple pathways and educational programmes raises the chances of meeting the interests of a diverse student population and the skills demands of a differentiated labour market. Challenges stemming from the integration of students from different socio-economic backgrounds, immigrants, students with special educational needs or those uninspired by traditional academic content have led countries to explore different policy options to cover the full spectrum of educational demand and provide ‚made-to-measure curricula‘ for students. Notably, this has resulted in multiple strands of offers, programmes and schools, which often raise efficiency and equity concerns.“
