The school offers all students a broad, balanced and relevant curriculum, including full entitlement to the National Curriculum, including a range of examination courses, as expected in any secondary school. After year 11, there is a 3-year partnership course with Peterborough Regional College for approximately 30 post-16 learners. These learners can be admitted with or without a statement but have a history of significant, additional educational need. They do not need to have studied at Marshfields' previously to apply.
The school has excellent facilities including generously proportioned, well-equipped classrooms, a computer suite, a library, and specialist rooms for Art, Design and Food Technology, along with Music and Drama. There is also a Gymnasium, and Community Room.
