Heathfield School's new Cadogan Sixth Form Centre was officially opened last week by former pupil Hon Mrs George Cadogan, who was joined by fellow old girl and BBC sports journalist, Laura Scott.
The new Centre was made possible thanks to the generous support of donors from across the Heathfield community.
The contemporary design of the building deliberately accommodates different styles of learning and study for pupils.
In addition to the new building, the school has launched a new Sixth Form Programme, designed to enhance the experience of the A Level years.
This programme will run alongside the academic side of Sixth Form life.
Headmistress Sarah Wilson said: "Academic work goes hand in glove with all the other aspects of Heathfield’s Sixth Form Programme to create well-rounded young people with a positive attitude and a good work ethic; young people who are well equipped to take their next steps, whether that is into higher education or the world of work."
She continued: "This project has taken several years to come to fruition through challenging times.
"I'm absolutely delighted to announce the opening of our new Sixth Form which will provide a much-needed larger space in which our students will be able to study, learn, meet mentors, develop their soft skills in one of our two presentation areas, and transition effectively into higher education and the working world.
"I would like to extend a 'very big thank you' to everyone who kindly contributed to our fund raising campaign."
