Seaford Head School was delighted this week after East Sussex County Council gave its plans to build a new sixth form centre the green light.
This means construction can start on the new facility in November and it should be finished by late June, in time for its opening in September 2014.
Pupils will now be able to stay in Seaford to complete their A-levels - at present they must travel to Lewes, Brighton or Eastbourne.
Head teacher Lynton Golds said: “This is a very exciting development for the local community of Seaford and all its neighbouring towns.
“As an all through 11-18 academy, with the addition of the new Seaford Head Sixth Form Centre, Seaford Head School will now be able to offer much needed alternative post 16 provision to this part of East Sussex.”
Planning permission was granted unanimously on Wednesday October 16 by the county council’s planning committee.
The sixth form will have two new science laboratories, two new ICT suites, several new classrooms and a large indoor social area.
The centre will be accessed from Steyne Road through a modern new entrance into a new reception area.
Seaford Head School said the sixth form had already attracted an enormous amount of interest from students already at the school, as well as applications coming from all the 11-16 schools in Eastbourne, Lewes, Newhaven, Peacehaven and Bexhill.
New head of sixth form Sarah Speedie has been visiting local schools and has spoken to students about the opportunities at the new sixth form centre.
A spokesperson for the school added: “The opening of the sixth form in September 2014 comes at the right time.
“Seaford Head School has had a reputation for many years as being a good school with outstanding features.
“The students and their parents can feel confident that the standards and expectations in the post 16 centre will be of that calibre.
“It also coincides with the government’s ‘raising of the participation age’ where all students are expected to stay on in education/training until the age of 18.”
The sixth form will provide academic AS/A2 Level 3 BTEC courses and a full programme of enrichment which will include the extended project, work experience, voluntary opportunities and the Duke of Edinburgh award.
There will also be expert careers guidance with visits to local and national universities including Oxford and Cambridge and other Russell group universities.
