A GROUP of students have said they are appalled and devastated after it was announced their sixth form is to close at the end of the year. Avon Valley Sixth Form, on Recreation Road, Durrington, announced on Friday it would be closing, blaming unacceptable financial challenges . A statement released by the Salisbury Plain Academies Trust said that since 2017, considerable effort has been put into increasing the size of the college and by 2020 numbers had increased to 31 in Years 12 and 13 combined. But, the trust say this figure remains significantly below a viable number and latest projections show that it would remain unsustainable for many years .
