 In its review of school teachers' pay in 2004, the School Teachers' Review Body recommended a change to the scale with effect from September 2006.Since that time, Advanced Skills Teachers have been paid on a scale of 18 pay points, which is identical to the first 18 points range of the Leadership pay scale, which is used for Head teachers, and Deputy and Assistant Headteachers.Unlike teachers employed on the main pay scale, Advanced Skills Teachers are not subject to the limits on working time of 195 days per academic year, or 1265 directed hours per year.
