More than £7m funding has been given to enable Cleethorpes Academy to complete its total refurbishment of the school.
Government funding was put on hold this year, but now a decision has been made to award the academy £7.7m.
Chief executive David Hampson said it would be used to turn the school into an "outstanding educational establishment" for young people.
The academy, which has 752 students, opened in September on the site of the failed Lindsey School.
Mr Hampson said the funding would ensure a total refurbishment of the academy, which would be built around a whole new curriculum structure in line with government policy.
Academy principal Martin Brown also welcomed the funding announcement.
"This funding will ensure that we can realise our goals of making this academy a beacon of excellence for Cleethorpes students, with facilities that will be second to none.
"It is wonderful news for the students and staff as we begin our Christmas break."
