The results follow significant changes in the grading system in the last two years, which saw a grading system of 9-1 introduced in English language, English literature and mathematics last year, being rolled out to 20 more subjects this year.
Provisional results show that 70.6% of pupils gained grade 4+ in English and maths which is expected to be above the national average.
Grade 5+ in English and maths are in line with last year’s results, and also expected to be above the national average.
Additionally, the average points score for six core subjects (known as the English Baccalaureate or EBacc) is 4.56 in York this year. Pupils who gain grade 9-4 in English, maths, two science subjects, a modern foreign language and a humanities subject achieve EBacc.
