About Glenthorne High School

Glenthorne High School is clearly a popular choice among local families. In the 2025/26 admissions round, the school received 1,867 applications for just 237 places, giving an oversubscription ratio of 7.88 to one. Of the 442 families who put it as their first preference, 191 were offered a place, meaning that even among those who really wanted to get in, fewer than half succeeded. That level of demand suggests parents in Sutton see something they like. The school is a mixed, non-religious secondary with a sixth form, and it currently has 1,782 pupils on roll, which is well above its official capacity of 1,558. That squeeze on space is a practical reality for anyone considering it: getting a place is competitive, and the odds are stacked against applicants who don't live very close or meet the admissions criteria.
