Miss White was succeeded by Miss Potts, who was Headmistress from 1930-38. But the next stage of growth for the school was overseen by Miss Worger, who was Headmistress for 28 years. Miss Worger aimed to increase student numbers to 500, and to enable this to happen 10 new classrooms were needed immediately, as well as a new hall, science labs and art and craft rooms. The building of the Manor started in 1962; this meant the school was able to accommodate 400 students by 1963.
