In 1994, one of the teachers from the school was jailed for five years after he admitted sexually molesting teenage pupils. In 2006, a detailed article was published by
Tes in which the teaching methods used by the school were discussed. It pointed out that these had been praised by school inspectors from the Independent Schools Inspectorate. The
Financial Times had said the school had the most improved A-level results for an independent school and had ranked it at number 46th in England. At that time, 90 per cent of teachers and 80 per cent of pupils were from Scientologist backgrounds but the deputy head said that its religious philosophies were not being taught. A 2012 newspaper report suggested that many students left the school after completing their GCSEs, without going on to the sixth form, in order to transfer to
Sea Org. Another similar report calls this a "rumour" but notes that, owing to the school's proximity to
Scientology's UK headquarters During the
COVID pandemic, the trust running the school was given £200,000 in UK government support. The school was inspected by the
Independent Schools Inspectorate in March 2024. Their report noted that standards relating to the quality of education and to leadership and management were not met. Recordkeeping and promotion of wellbeing of pupils was also deficient, and required standards relating to pupil safeguarding were not met. Day pupils and especially boarders had insufficient outside activities, recreation, and free time. Boarding accommodations only met minimal standards. Greenfields announced that as of July 31, 2024 they were no longer able to sponsor students from outside the UK because their ability to sponsor had been withdrawn by
UK Visas and Immigration. ==Notable alumni==
