How do you become a teacher, and what routes exist?
Through one of several routes to qualified teacher status, which differ mainly in whether you train mostly at a university or mostly in a school, and in whether you are paid while training. The qualification at the end is broadly the same; the experience of getting there is not.
The main routes in England:
University-led postgraduate training (PGCE), combining university study with school placements. You pay fees and may receive a bursary or scholarship, which in shortage subjects can be substantial.
School-led training, where a school or group of schools leads, with more time in the classroom from the start. Some versions are salaried, so you earn while training — these are competitive and frequently aimed at career changers.
Undergraduate routes, where a degree includes qualified teacher status.
Assessment-only, for those already teaching without the qualification, assessing existing practice against the standards rather than requiring a training year.
Teach First and similar programmes, placing trainees in schools serving disadvantaged communities, with a leadership development element.
What is required to start:
A degree, with subject relevance mattering more for secondary.
GCSE grade 4 or above in English and mathematics, plus science for primary. This requirement blocks more applicants than any other, and equivalency tests are accepted by many providers.
A criminal record check, and a fitness to teach assessment.
School experience, which strengthens an application and is increasingly expected.
What happens after qualifying: an induction period across the first two years, with a reduced timetable and structured support under the early career framework — designed to address the fact that a high proportion of teachers leave within their first five years.
Scotland, Wales and Northern Ireland have separate systems with their own registration bodies.
Worth knowing before committing: the workload and retention data are public and sobering; shortage subjects carry much larger financial incentives; and spending time in a school first is the single most useful thing you can do before applying.
