AET vs CAVA vs DET: Which FE Qualification Do You Need?

Navigating the world of Further Education and Skills qualifications can feel like trying to decipher an alphabet soup of acronyms. For leaders building their teams and professionals planning their careers, understanding the difference between key qualifications is crucial. AET, CAVA, DET - what do they mean, who are they for, and which one does your organisation or team member actually need?

This guide breaks down three of the most common qualifications to help you make informed decisions about professional development, ensuring your team has the right expertise to deliver high-quality provision.

The Gateway: Level 3 Award in Education and Training (AET)

The AET is the go-to entry point for anyone new to teaching or training in the FE and Skills sector. It provides the essential foundations without the commitment of a full diploma.

Who is it for? It is ideal for industry experts transitioning into a training role, staff who deliver short courses or workshops, or individuals wanting an introductory qualification before committing to a full teaching career.
Level and Size: As a Level 3 Award, it is accessible and manageable. It typically involves around 48 guided learning hours (GLH) and consists of 12 credits.
What it covers: The AET focuses on the fundamentals: understanding your role and responsibilities as a teacher, planning and delivering inclusive learning sessions, and using different assessment methods. A key component is a practical micro-teach session where you demonstrate your skills in a controlled environment.
Career path: The AET is a stepping stone. It qualifies you for entry-level teaching or training roles, often delivering non-accredited learning or supporting a lead tutor. For many, it's the first step towards the full Level 5 Diploma.
WorkplaceHero, through our sister company, offers the Focus Awards Level 3 Award in Education and Training (AET) to equip your new trainers with these core skills.

The Specialist: Level 3 Certificate in Assessing Vocational Achievement (CAVA)

Unlike a teaching qualification, CAVA is laser-focused on a specific, critical function: assessment. This is the qualification for those who need to formally assess the competence of learners.

Who is it for? It is designed for practitioners who assess vocational skills, knowledge, and understanding. This includes assessing learners in the workplace (e.g., apprentices) and in a training environment like a college or workshop.
Level and Size: This Level 3 Certificate is more substantial than the AET, typically requiring around 84 GLH and totalling 15 credits. Critically, it requires access to at least two real-life learners to assess.
What it covers: CAVA is comprehensive, covering the principles and practices of assessment, how to assess vocational competence in the workplace, and how to assess knowledge and understanding in a different context. It ensures assessors are consistent, fair, and follow regulated procedures.
Career path: CAVA unlocks roles such as Vocational Assessor, On-programme Assessor, or End-Point Assessor (when combined with deep occupational expertise). It is the industry-standard qualification for anyone whose primary role involves making assessment decisions about learners' competence.
We also offer the Focus Awards Level 3 Certificate in Assessing Vocational Achievement (CAVA) to ensure your assessment practice is robust and reliable.

The Goal: Level 5 Diploma in Education and Training (DET)

The DET is the recognised, professional teaching qualification for the FE and Skills sector. It is a significant undertaking that qualifies an individual to teach as a Fully Qualified Teacher (Learning and Skills).

Who is it for? This qualification is for individuals committed to a full-time or substantial teaching career in FE, whether in colleges, independent training providers, or other skills settings.
Level and Size: At Level 5, this Diploma is equivalent to a foundation degree. It is a major commitment, involving around 360 GLH and 120 credits. It requires a minimum of 100 hours of teaching practice.
What it covers: The DET goes into significant depth on teaching theory and practice. Learners explore curriculum design, inclusive teaching strategies, advanced assessment techniques, theories of learning, and professional practice. It often includes specialist pathways to align with your subject area.
Career path: Completing the DET allows you to apply for Qualified Teacher Learning and Skills (QTLS) status. QTLS is recognised in law as having parity with Qualified Teacher Status (QTS) in schools, opening up a wide range of career opportunities as a professional lecturer, tutor, or trainer across the education sector.

AET vs CAVA vs DET: A Quick Comparison

To put it simply:

AET: The starting point for teaching.
CAVA: The required qualification for assessing.
DET: The professional standard for a teaching career.

A single person might need different qualifications at different stages of their career. An experienced tradesperson might start with an AET to begin training apprentices, then take the CAVA to become their formal assessor. Someone else might go straight from the AET to the DET to pursue a full-time lecturing role. They are not competing qualifications but distinct tools for different professional jobs.
