Age to Become a Teacher in the UK: What You Need to Know

Want to know how old you have to be before you can step into a classroom as a teacher? The answer isn’t just a single number – it depends on the path you choose, the part of the UK you’re in, and the type of teaching you want to do. Below we break down the basics so you can plan your journey without guessing.

Legal Minimum Age

In England, Wales, and Northern Ireland the statutory minimum age to start teacher training is 18. You can enroll in a PGCE (Post‑graduate Certificate in Education) or an School Direct programme as soon as you have a bachelor’s degree, which most people finish around 21‑22 years old. If you want to become a primary teacher, the same 18‑year floor applies, but you’ll need a degree in any subject first.

Scotland runs a slightly different system. The required qualification is a Professional Graduate Diploma in Education (PGDE). You must be at least 18 and hold a degree, so the practical entry age is again about 21‑22. Some apprenticeship routes let you start at 18, where you earn while you learn on the job.

There’s also a special route for assistant teachers or teaching assistants. Many schools will hire you at 16 if you have GCSEs, but you won’t become a fully qualified teacher until you complete the proper training.

How to Start Early

If you’re keen to hit the classroom sooner, consider these steps:

Volunteer or cover work: Schools often need supply teachers or classroom helpers. Getting your foot in the door early builds experience and contacts.
Earn a Level 3 Teaching Assistant qualification: This can be done at 16‑17 and shows commitment. It also counts toward entry requirements for some university courses.
Take a relevant degree: Choose subjects like Education, Childhood Studies, or any subject you love. A strong degree can shave months off the waiting time for a training place.
Apply for a teaching apprenticeship: Apprenticeships combine work and study, letting you earn while you qualify. They start at 18 and are open to anyone with a level 3 qualification.

Remember, age isn’t the only factor. Schools look for passion, communication skills, and a clear understanding of what teaching involves. A short placement or a few weeks volunteering can prove you’ve got the right mindset.

One practical tip: keep an eye on the UCAS Teacher Training deadlines. Applications usually close in December for courses starting the following September. Missing the window can push your start date back a year, so plan ahead.

Finally, don’t forget the paperwork. You’ll need a Disclosure and Barring Service (DBS) check and a health assessment before you can set foot in a classroom. These checks can take a few weeks, so factor them into your timeline.

Bottom line: you can legally start teacher training at 18, but most people begin around 21 after earning a degree. Use volunteer work, assistant roles, or apprenticeships to gain experience early, and you’ll be ready to walk into a classroom as soon as the paperwork clears.
