The Gateway Learning Community Trust's CEO, Mr Kevin Sadler, added "Grainne and her team have created something really special at Gateway; not only are results improving significantly, but the ethos is just wonderful".
"With these national changes, year-on-year comparisons of attainment are not appropriate and headline progress measures will be unavailable until the official performance tables are released".
Also, of the five Year 9 pupils who sat the entry level computing paper by way of preparation, two achieved Grade 3, the highest grade available.

Next year more subjects will be incorporated into the new system and by 2020 all subjects will be numerically graded.
"It is always hard to refer to specific results and individual students but the incredible amount of A*-A grades achieved by the year group as well as 19 subjects securing a 100 per cent pass rate would be the most satisfying".
