To put it simply regulations state that all classes must be assigned a qualified teacher to teach them. But that is contradicted by guidelines that say that support staff may be allowed to carry out specified work under the direction and supervision of a qualified teacher, But there are also indications that schools may use HLTAs for that purpose but nowhere does it say that TAs may do so. In fact the DfE has stated on many occasions that support staff and teachers are not interchangeable or that support staff should be used as substitutes for teachers. Nick Gibb has stated that headteachers should follow all the regulations and guidelines but he is being continually ignored. Furthermore the DfE has stated that if any individuals object to the way in which schools implement the regulations and guidelines they should make an official complaint to the school.
