These include teaching assistants, special needs support staff, ethnic minority student support staff and other pedagogical support staff. Exclude non-teachers who support individual or primarily individual students. With the exception of those covered under Article 4, families in these groups are also subject to a maximum household income threshold of £31,500 per year for London and £28,200 for areas outside London. The cost threshold specified for additional SEN support varies depending on the type of deployment. For primary and secondary schools and academies, the threshold is £6,000 per pupil per year in all cases. The premium is paid for individual students whose additional support costs more and for excess costs is above the threshold. .
