Thinking about where to start (or specialise) as a Teaching Assistant? The day-to-day reality can look very different in Primary, Secondary and SEN (Special Educational Needs) settings. Here’s a clear comparison of duties, pace, skills and progression so you can choose the environment that fits you.

At a glance: key differences

Primary — what it feels like

• Core work: phonics, guided reading, spelling, number facts, handwriting, learning through play (EYFS).
• Rhythm: one main class most of the day; close relationships with pupils and families.
• Best if you enjoy: nurturing early learning, daily routines, creative resources, craft and displays.

Secondary — what it feels like

• Core work: subject-based support (English, Maths, Science, Humanities, Options), revision/intervention groups.
• Rhythm: bell-driven timetable; moving between rooms; frequent behaviour resets.
• Best if you enjoy: subject depth, coaching independence, working across departments.

SEN (mainstream & special) — what it feels like

• Core work: adapting materials, communication support (visuals/structured routines), regulation and calm spaces.
• Rhythm: very individualised; small steps progress; close multi-agency teamwork.
• May include: personal care, mobility assistance, medical/healthcare protocols (training provided).
• Best if you enjoy: patience, empathy, collaboration with therapists and families.

Which qualification fits all three?

• Default: Level 3 Certificate/Diploma in Supporting Teaching & Learning — fully qualifies you with in-school evidence.
• Fallback: Level 3 Award (knowledge-only) if you can’t access a placement yet; upgrade later in role.
• Extras (helpful CPD): phonics (Primary), subject literacy/numeracy (Secondary), autism/communication & regulation (SEN).

Choosing a placement

• Pick the phase you’re most drawn to — your evidence will reflect that setting.
• You can split time across two settings with provider approval if it helps you meet all standards.
• Ask about expectations (e.g., personal care in SEN) before you commit; training is usually provided.

Timetable, hours & contracts

Hours vary (e.g., 25–32.5 per week) and many roles are Term-Time Only with pay annualised over 12 months. See Term-Time Only explained and TA Salary & Hours.

Frequently Asked Questions

Can I move from Primary to Secondary (or to SEN) later?

Yes. Your Level 3 STL is recognised across phases. You may need phase-specific CPD (e.g., phonics for Primary, subject literacy for Secondary, communication/regulation for SEN).

Do I need a different qualification for SEN?

The Level 3 STL Certificate/Diploma is widely accepted. Some settings value additional SEN CPD and relevant placement evidence; training is usually provided in role.

Is SEN “harder” than mainstream?

It can be more specialised and physically/emotionally demanding, but also highly rewarding. Ask about support, staffing ratios and training before you commit.

Will Secondary experience count against me if I later apply to Primary?

No, but you should show Primary-relevant evidence (e.g., phonics/early reading). Short Primary volunteering can help bridge the gap.

Can I split a placement across two settings?

Often yes, with provider approval. You must still meet the minimum weekly hours and gather evidence across the required standards.
