The University of Cambridge has set four access (admissions) targets for the 2020-21 to 2024-25 Access and Participation Plan: to increase the proportion of UK resident students admitted (i) from UK state maintained sector schools/colleges, (ii) from POLAR4 quintile 1 areas, (iii) from POLAR4 quintile 1 or 2 areas, (iv) from regional IMD quintile 1 or 2 areas. This paper outlines the methodology used to formulate these targets.
