At the latest Ofsted inspection, St Marylebone was judged "outstanding in every respect". In 2013, exam results were the best in Westminster and the school topped the DfE League Table comparing all schools nationally with a similar intake. For the 11th year running, well over 90% of GCSE entries received A*-C grades and more than half received A* or A. St Marylebone is one of the most oversubscribed schools in London; in 2013, almost 7 students applied for each of the places available in Year 7. It is the top non-selective school in London.
