The number of teachers without qualified teacher status in all state funded schools in England, including a breakdown by primary and secondary, and by local authority, is available at: https://explore-education-statistics.service.gov.uk/data-tables/permalink/29d83b82-2aba-44c7-bb82-08db371944c7. Data relating to schools in individual constituencies can be found in the ‘teacher and support staff numbers by school’ file, within the additional supporting files section, available at: https://content.explore-education-statistics.service.gov.uk/api/releases/0728fb07-f014-492c-aac9-fd11bb441601/files/2dfcc772-c410-46ac-cb9d-08da713e9200. There are 24,000 more teachers now than in 2010. The quality of teaching is the most important in school factor in improving outcomes for children, especially for those from disadvantaged backgrounds. Evidence is clear that high quality professional development can lead to improved pupil attainment. The Department has invested in transforming training for teachers and head teachers. Every teacher and head teacher now has access to high quality, evidence based training and professional development at every stage of their career, starting with initial teacher training (ITT). By 2024, a reformed ITT provider market will be delivering quality assured training leading to qualified teacher status (QTS) that places a greater emphasis than ever before on embedding structured practice into courses, ensuring trainees are ready to thrive in the classroom. A new system of higher quality training provider partnerships will be supported by £36 million to introduce new Quality Requirements, including better training for mentors and the delivery of new, cutting edge, intensive training, and practice activity. Every teaching school hub will be involved in ITT to ensure that training places are available across the country. QTS is considered desirable for teachers in most schools in England. In some schools, including academies, free schools, and independent schools, QTS is not a legal requirement. Academies have a fundamental freedom to employ talented people who do not necessarily have QTS. Most teachers in all schools, including academies, have QTS and have undertaken initial teacher training. In the 2021/22 academic year, the latest data available, 14,771 teachers (headcount) did not have qualified teacher status, equivalent to 2.9% of teachers.
