If you’re planning to build a career in teaching, training, or adult education, choosing the right qualification is an important first step. Two of the most popular teaching qualifications in the UK are the Level 3 Award in Education & Training (AET) and the Level 4 Certificate in Education & Training (CET).
Both qualifications are recognised across the education and training sector, but they are designed for different stages of a teaching career. Understanding the differences between these courses will help you choose the one that best matches your experience, career goals, and professional development needs.
What is the Level 3 Award in Education & Training (AET)?
The Level 3 Award in Education & Training (AET) is the entry-level teaching qualification for individuals who want to teach or train adults. Formerly known as PTLLS (Preparing to Teach in the Lifelong Learning Sector), this qualification provides a solid foundation in teaching principles and classroom practice.
The course introduces learners to the responsibilities of a teacher, lesson planning, assessment methods, and effective teaching strategies. It is suitable for people with little or no previous teaching experience and is often the first step towards a rewarding career in education.
The Level 3 AET is ideal for individuals who want to teach in:
- Further Education Colleges
- Private Training Providers
- Adult Learning Centres
- Community Education
- Workplace Training
- Corporate Learning
- Vocational Training
No previous teaching qualification is normally required, making it accessible to beginners and career changers alike.
What Will You Learn in the AET Course?
The Level 3 AET focuses on the essential skills required to become an effective teacher or trainer.
Key topics include:
- Understanding the roles and responsibilities of a teacher
- Planning effective learning sessions
- Creating inclusive learning environments
- Delivering engaging lessons
- Communication and presentation skills
- Assessment principles
- Giving constructive feedback
- Equality, diversity, and inclusion
- Safeguarding responsibilities
Most AET courses include a short micro-teaching session, allowing learners to practise delivering a lesson and receive valuable feedback.

Formerly known as CTLLS (Certificate in Teaching in the Lifelong Learning Sector), the CET develops more advanced teaching skills and prepares educators to take on greater responsibilities in further education and vocational training.

The qualification encourages teachers to evaluate and improve their own teaching practice while developing confidence in managing different learning environments.

The Level 3 AET introduces the fundamentals of teaching, while the Level 4 CET develops practical teaching expertise and reflective practice.
