Volunteering as a Teaching Assistant (TA – or also known as classroom assistants or learning support assistants in some schools) is a wonderful way for Christian parents to give practical support to the school community. Often TAs are parents of children who are attending or who have attended the school. The work is flexible, rewarding and often a stepping stone towards becoming a teacher. There are no formal qualifications required for being a TA – although your local education authority (LEA) will have guidelines as to what sort of people they are looking to employ.
