Highbury College will be marking its emerald anniversary throughout the academic year with 1960s themed projects, events and activities.
Originally a single-site campus, the College started with a student population of nearly 5,000 despite originally being designed for 2,800 students.
At the time, it had six departments including Building & Surveying, Commerce & General Studies, Domestic Studies, Engineering, Mathematics & Science and Hotel & Catering.
Since then Highbury has expanded several times and currently teaches over four locations throughout Portsmouth.
It has also vastly broadened the variety of courses it provides, including in journalism, IT, automotive, and hairdressing & beauty therapy.
Highbury is also proud to say 94 per cent of students are happy overall with their course and the College, according to the most recent student satisfaction survey.
Principal of Highbury College Stella Mbubaegbu CBE said: "Throughout its 55-year history, Highbury College has been privileged to serve the local community, and we are immensely proud to the hundreds of thousands of students who have achieved so much during this time. We are now, as ever, committed to providing a world-class learning experience for our students and look forward to many more years of success."
