Included in the school is Great Cornard Sports Centre, which is open to the public outside of school hours, funded in part by a £563k grant from the English Active lottery fund. The complex features a youth drop-in-centre, dance and martial arts studios, changing rooms, fitness studios, a coach education unit and a social area. The school also completed the building of a Sixth Form study block and library in 2009.
Reconstruction
In 2012, the school was granted funding for a total rebuild. Work commenced on the new building in June 2014 and was completed in August of 2015. The new facilities of the £17 million pound site include a reading room, roof terrace and 9,124 sqm of space. Whilst the main complex of the old school site were demolished, the library and sports centre were not and are still utilized by the school. Additionally, the old site of Great Cornard Middle School that was acquired by Thomas Gainsborough School after the switch to a two-tier system remained, with the building now being used as a Sixth Form and Media centre.
Academic performance
In their report on the school in September 2017 Ofsted gave an overall rating of the school as Good, point two on a four-point scale. The personal development, behaviour and welfare of pupils was described as outstanding. Results for pupils at age 16 showed clear improvement between 2006 and 2009 outperforming both local and national indicators for pupils gaining 5 GCSE grades between A* and C, including English and Maths. In 2009 the school had the best contextual value added scores of any school in Suffolk.
