The current headmistress is Lisa Pritchard, previously head of the prep school, who succeeded Robert Carnevale on his retirement in 2023.

By 1946, the school was housed in Nant Coch House, Risca Road, Newport, and the number of pupils increased to approximately 200.When the Evans' retired in 1974, a number of families raised a loan to buy the school, electing a board of nine governors.

The Stow Hill buildings, formerly housing the Convent of St Joseph were purchased, and provision was extended first to Common Entrance level, then to O-levels and finally the first A-levels were taken in 1983 under the leadership of Frank Edwards.

Under the headship of Sims the school moved to its present site, Llantarnam Hall, a large Victorian mansion set in 50 acres (200,000 m2) of parkland on the outskirts of Newport, in 1992.
