The Department publishes pupil attainment data through a number of headline measures for each local authority and region of England; these figures can be compared to the national (England) average for all pupils.
The headline measures for 16-18 study for each local authority and region in England for the academic years 2009/10 – 2017/18 are available here: https://www.gov.uk/government/collections/statistics-attainment-at-19-years.
Due to A and AS Level reforms and changes to headline measures (including methodological changes), the available figures are only directly comparable between 2009/10 – 2014/15 and 2015/16 – 2017/18.
The last five years’ figures for A Level results for England, the West Midlands region, and Coventry Local Authority are summarised in the tables attached. Constituency level information is not published for 16-18 performance measures.
 For each year, select the ‘revised’ publication and then open the ‘Local authority tables’. For 2015/16 - 2016/17 the headline attainment measures are the average point score (APS) per entry and APS per entry expressed as a grade for each qualification type. These can be found in table ‘9a all’ (2017/18); table ‘9a all’ (2016/17); table 9a (2015/16); table 12c (2014/15); table 12a (2012/13 - 2013/14); table 9a (2011/12); table 10 (2010/11); table 9 (2009/10).
