If you are a retired teacher you may consider going in to tutoring. Unlike working in a school, you can often pick and choose the hours you work and fit it in around your life style. It allows you to carry on teaching in a way but without all the added commitments.
You don’t actually need a degree in the subject you want to teach, but a degree in core educational subjects, including maths, English, science and modern languages, may be useful when tutoring in these subjects. This means that even if you have never been a teacher, you can still be a tutor. It is important that you fully understand the subject that you intend to tutor and that you understand the syllabus that the students’ needs to follow.
It may be that you just offer exam tutoring where you basically run revision classes. This is often called for as students approach their GCSE’s or A-levels and need a little extra help in structuring their revision.
It may be that you offer adults tutoring for people that maybe didn’t complete their education at a young age or struggle to keep up with the maths and English that their child is doing at school.
