School teaching salaries are based on pay scales drawn up by the government in April of each year. These are based on teacher location and status: Teachers working in central London receive the highest bracket, followed by the London fringe, outer London and then the rest of the country. The pay scales are then divided into unqualified, average NQT qualified and upper level status, with pay rates rising depending on placement in the above locations. A teacher can progress through these stages during their careers and be paid accordingly. Unqualified teachers who have not attained an NQT certificate but still work in the education service can expect a range from �14, 751 to �23, 331 for general UK work and �18, 552 to �27, 129 for central London employment. Qualified teachers who have attained the NQT certificate will be paid from �20, 133 to �29, 427 for general UK work and �24, 168 to �33, 936 for central London. Those in the upper pay scale, which might include head-teachers and course convenors, can expect to receive a general yearly salary of �31, 878 to �34, 281 in the UK and �37, 808 to �41, 004 in central London.
