Both teams won their regional athletics finals held at the Meres Athletics Stadium in Grantham.
A school spokesman said: “Both teams gave commanding performances to win against school teams from across the East Midlands.”
The junior girls (pictured below) finished with an impressive 345 points, following strong performances in the javelin, long jump and hurdles.
Meanwhile the intermediate girls (above) finished in first place with 322 points, again with strong performances in javelin and hurdles, but also in the 100 metres and the high jump.
The spokesman added: “Both teams did exceptionally well on the day. Special mention goes to performances from Laura Van Lier and Rosie Fresen for the intermediate girls team and Olivia Thompson and Macy Carr for the junior girls team.”
