What does a teaching assistant actually do?
Far more than the popular image of someone sharpening pencils. Teaching assistants are a substantial part of the school workforce, and what they do varies enormously between schools — which is itself the central problem with the role.
The common responsibilities:
Supporting individual pupils, frequently those with special educational needs or an education, health and care plan, where support may be funded specifically.
Working with small groups, delivering structured interventions in reading, phonics or numeracy.
Supporting the whole class, circulating during independent work, checking understanding and managing behaviour.
Preparing resources and displays, administration and record-keeping.
Pastoral and personal care, including medical and intimate care for some pupils.
Higher level teaching assistants may plan and deliver lessons and cover classes.
What the evidence says, which is the important part and is frequently misreported. Influential research found that pupils receiving more TA support sometimes made less progress than similar pupils receiving less — not because TAs are ineffective, but because of how they were deployed. The pattern identified was that the pupils with the greatest need were separated from the teacher and from the curriculum, receiving most of their instruction from the least-qualified adult, with TAs frequently prompting and supplying answers rather than developing independence.
What works instead, according to the same body of research: TAs delivering structured, evidence-based interventions they are trained in, in short regular sessions, explicitly linked back to classroom teaching; being used to supplement rather than replace the teacher; and being given preparation time and briefing.
The structural issues are real: low pay, frequently term-time only and part-time; limited career progression; funding pressures making the role an early target for cuts; and variable access to training.
If you are considering the role, it is a genuine route into teaching for many, offers considerable satisfaction, and should be entered with clear eyes about pay and hours.
