Thorpe St Andrew School has decided to become an academy, and set up a trust to sponsor other academies.
Thorpe St Andrew School today told the Department for Education it will submit an application to convert.
The school, which Ofsted judged 'outstanding' in 2014, is one of the few remaining Norfolk high schools that has not yet converted.
The school's governors launched a consultation on possible conversion last term, and have now voted unanimously to seek multi-academy trust status, with the school as the principal sponsor of the trust.
In a statement, the school said the decision has been taken after 'extensive research and discussion and has been informed by all representations made during the consultation period'.
It said: 'Governors are committed to maintaining the school's current ethos and values, and we will use the opportunities that multi-academy trust status brings to enable the school not only to build on its already outstanding record of success but also to draw together other like minded schools in our area.
'Governors hope to develop yet further the already excellent progress made within the Thorpe St Andrew Educational Partnership, which will enable current and future students, from the age of 3 to 19, to experience both continuity as well as quality of education within our own local community.
'The process of deliberation and consultation has generated excitement and a sense of expectation as the school contemplates its future role. As a teaching school we anticipate creating enhanced opportunities for collaborative working with other schools, in line with our beliefs about what an outstanding education means for all pupils and students.
'Our own students and staff will benefit from the sharing of good practice within the new Trust as we help to shape the nature of education in our community.
'We invite students, parents, staff and the wider community to support us as we evolve and to help us make the vision a reality.'
Norwich South MP Clive Lewis, who is patron of the Anti-Academies Alliance, is an associate governor of the school.
