Its letter

How the letter is worked out

Northern Ireland selects at 11. Grammar schools average 94% of pupils with five good GCSEs including English and maths, non-grammar schools 60%. Ranked against all 186 schools together, a non-grammar school would be held to grammar-school intakes, and a grammar school would look outstanding for its intake alone. So St Colmcille's High School’s C is its place among Northern Ireland’s 120 non-grammar schools: better than 31% of them. Among all schools it is better than 20%.

The bands are the site’s own: A+ is the top 5%, A the next 10%, and so on down to D− for the bottom 5%. It rests on one year’s results; Northern Ireland publishes no progress measure.
