Are you ready to grow your teaching career in the UK? Many educators get stuck at the same point. They hold the Level 3 Award in Education and Training. Now they need to go further. Two qualifications sit in front of them.
The Level 4 Certificate in Education and Training (CET) and the Level 5 Diploma in Education and Training (DET). Both serve teachers and trainers in the Further Education and skills sector. But they open very different doors.
So before you spend time and money, ask yourself this: are you teaching under supervision, or are you ready to lead a room on your own?
What Are the Level 4 CET and Level 5 DET Qualifications?
These two qualifications replaced older ones. The Level 4 CET replaced CTLLS. The Level 5 DET replaced DTLLS. They are now the current, active qualifications for FE and skills sector educators in the UK.
They are both recognised by awarding bodies that have been approved by Ofqual. They both build upon the Level 3 Award in Education and Training (AET) which is the gateway to most new trainers and teachers.
Level 4 CET: What It Is and Who It Is For
The Level 4 Certificate in Education and Training (CET)is an RQF Level 4 qualification. It includes around 39 credits and approximately 100 guided learning hours. It is designed for teachers and trainers who deliver learning under supervision.
This qualification is ideal if you hold the Level 3 AET. It is also suited to those in adult education, workplace training, or private training providers. Your teaching sessions are still supervised at this stage.
Who Should Choose the Level 4 CET?
Here is a clear picture of the right candidate for the CET.
You are a good fit if your employer specifically asks for Level 4 recognition. You’re also a good fit if you’re developing your career slowly. Before moving on, the CET will assist you with lesson planning, assessment and inclusive teaching.
Level 5 DET: What It Is and Who It Is For
The Level 5 Diploma in Education and Training (DET) is at RQF Level 5. It has 120 credits and 370-420 guided learning hours. It takes most learners 9 to 18 months to complete on a part-time basis.
This is the full teaching qualification for the FE and skills sector. It allows you to teach unsupervised, take on complete timetabled sessions, and apply for QTLS status through the Society for Education and Training.
Who Should Choose the Level 5 DET?
The DET is the right choice for educators who are ready to teach independently and take full responsibility for planning, delivering, and assessing learning.
You need it if you want to work as an FE lecturer, a skills coach, or a curriculum developer. You also need it if QTLS is your end goal. Many employers in the skills sector now set Level 5 as the minimum entry bar for advertised posts.
Key Differences Between Level 4 CET and Level 5 DET
Below is a side-by-side comparison of both qualifications.
| Feature | Level 4 CET | Level 5 DET |
| RQF Level | 4 | 5 |
| Credits | Typically 33 to 36 credits | ~120 |
| Guided Learning Hours | Around 140 | 370 to 420 |
| Teaching Status | Supervised | Unsupervised |
| QTLS Eligible | No | Yes |
| Typical Duration | A few months | 9 to 18 months |
| Best For | Bridging Level 3 to 4 | FE roles, skills coaches, QTLS |
The gap between them is significant. The DET involves roughly three times the study load of the CET. Picking the wrong one wastes both time and money.
What You Will Learn on Each Course
Both qualifications develop your teaching practice, but at different depths.
The Level 4 CET focuses on roles and responsibilities in education, planning for varied learners’ needs, delivery methods, formative assessment methods, summative assessment methods, using resources efficiently, and reflective practice.
It requires a greater commitment both academically and in the classroom, with more advanced teaching practice and professional development.
Which Teaching Qualification Is Right for You?
It will depend on your current position and your future aspirations. Here is a step-by-step tutorial.
Choose the Level 4 CET if:
- You hold the Level 3 AET and teach under a mentor
- Your employer funds staged career progression
- Your job advert specifically requires Level 4
Choose the Level 5 DET if:
- You want to teach fully independently
- You are targeting an FE college or skills coach role
- You plan to apply for QTLS status
- You already deliver sessions solo without formal Level 4 behind you
Many providers allow eligible learners to progress directly from the Level 3 AET to the Level 5 DET, provided they meet the entry requirements.
Can You Progress from the CET to the DET?
Yes, and this is good news for anyone who has already completed the CET.
Most awarding bodies will recognise CET into DET units as either credit transfer or Recognition of Prior Learning (RPL). This does not require you to begin the diploma “from scratch. Please be sure to confirm with your providers before signing up. The number of credits awarded for maps across varies by awarding bodies.
Frequently Asked Questions
Can I skip the Level 4 CET and go straight to the Level 5 DET?
Yes. Most providers accept direct entry to the DET if you hold a Level 3 AET and meet their entry criteria.
Does the Level 5 DET qualify me for QTLS?
Yes. QTLS applications through the Society for Education and Training require a Level 5 teaching qualification as a prerequisite. The CET does not meet this requirement.
How long does the Level 5 DET take?
Most part-time online routes take between 9 and 18 months, depending on your pace and teaching commitments.
Is the Level 5 DET the same as a PGCE for FE roles?
Many FE colleges treat both as equivalent. Always check the specific job advert to be sure.
