I/GCSE Results

Our I/GCSE results this year have set new standards of achievement for our students and our school.

In a year in which the percentage of A* grades has, once again, fallen in the UK (to 6.6%), BOS students have bucked that trend. This year our students have accumulated 77 A* grades (41%). This surpasses our previous two years by some distance and reflects the exceptional standards that our students and teachers have set for themselves.

All of our students have garnered the five passes at GCSE (C and above, including Mathematics and English language) that the UK Government uses as a benchmark of quality.

Five of our students gained only A*/A grades in their ten I/GCSE examinations. Many congratulations to Mina Hasan, Fatima Jafar, Laleh Jamil, Alishba Makhdoom and Aadil Lodi for their considerable achievements.


Although these I/GCSE results are clearly very good, we use more complex measures to determine just how good they are and the role that the school has played.

It is, of course, very possible that the Year 11 of 2014-15 was simply very bright and that their teachers played little or no role in their achievements.

One of the measures we use is "value-added". This is a measure of the contribution that the school and its teachers have made over the course of the students' secondary school development. We are able to do this using the CEM assessments that are provided and assessed by Durham University in the UK.

The process begins in Year 7, when the students are assessed in October. In the case of this cohort, that was about a month after joining the secondary school from primary. Based on these assessments, Durham University is able to predict the path of the academic development that the students should follow over the next five years. The university predicts the GCSE grades that students should typically expect to gain at the end of Year 11. The "should" comes from the typical GCSE grades of all of the students with those scores in their Year 7 assessments.

Value-added is the extent to which our GCSE students are able to exceed these expectations. It represents the additional value that students gain because they attend the BOS rather than a 'typical school'.

I am very happy to report that the average value-added for 2013-14 was 0.92 of a GCSE grade. In 2014-15 the value added was 1.02 of a GCSE grade. This means that those students who attended the BOS for their secondary education achieved one full GCSE grade higher than they would have done in a "typical school".
