For the under-14s, Grace Hooper and Charlotte Jessop got through to the 100m final with Hooper coming third. Jessica Breach and Hooper qualified for the 200m and were first and third.
Hooper has now been asked to represent West Sussex in the 100m and Breach in the 200m at the Sussex county championships in June.
In the 4x100m relay, Hooper, Libby Swan, Breach and Megan Adams were second in their heat to get into the final – and they then stepped up their performance to win the final. They have also been asked to represent West Sussex at the county championships.
Adams came third in the long jump, Hooper achieved third in the javelin and Portia Wilson-Smith was in the shot putt.
Lavant House was third overall out of 12 schools, many of the others being much larger.
The under-16s also tasted success.
Maddie Leaver and Pip Rainbow got through to the 200m final, in which they came fifth and sixth.
Rainbow was second in the 800m final and will represent West Sussex in the counties alongside Natalya Fagerlund, who was second in the 1,500m final.
The relay team of Camilla Langmead, Polly Waters, Rainbow and Georgie Osborn came second in their heat and just missed second in the final.
Langmead completed some excellent high jumps – she cleared 1.39m to finish third and has also been selected for the counties.
The under-15s did not achieve a placing but considering they were from the third and fourth forms and up against slightly-older girls, they did well.
