Compare the two types of help
General academic and organisational support
The focus is how your child approaches work across subjects: finding the task, breaking it into steps, choosing a starting point and reviewing what is complete. Ask for these routines to be practised on actual schoolwork. A homework session in which an adult keeps supplying answers may get the work finished without teaching the routine.
Subject specialist support
The focus is a particular area of learning: for example, equivalent fractions in Maths or explaining an inference from a passage in English. Ask the tutor to explore the child’s reasoning, teach the missing idea and offer a new task that tests it. Specialist subject knowledge and a clear explanation should work together.
A combined approach
A child can need both. A subject tutor may be able to model planning and self-checking through their subject, while home and school use the same practical organisation routine. Agree who is doing what. Do not assume one tutor covers every subject or that two tutors are automatically necessary.
