The fate of New Mills Sixth Form is still undecided after discussions concerning its possible closure were pushed back.
After a consultation with parents, governors have called for the facility to be closed. The final decision will lie with Derbyshire County Council and its cabinet.
The matter was due to be discussed at a meeting on Tuesday, but has been deferred until September because of new reports and a 1,800-strong petition.
Campaigner for Save New Mills Sixth Form, Marcus Hewitt, said: “This really will put the future education of the pupils in jeopardy.
“If a decision is not going to be made until September the pupils who will be going into Year 11 and making choices about their post-16 education won’t be picking the sixth form because of the uncertainty of it, so with no students enrolling you can see it would be easy to shut it down which is wrong.”
The group has submitted a report which outlines how the sixth form, on Church Lane, can become viable with a broad range of academic and vocational subjects.
Marcus added: “I hope that the cabinet use this time to consult us properly.”
