Joint advice from the NUT and other unions on school teachers' pay from September 2017 is available here. It advises that the percentage uplift recommended by the STRB to the minima and maxima of the ranges (2% for the Main Pay Range and 1% for other pay and allowance ranges) should apply to all teachers within the relevant range. The advice is endorsed by ASCL, ATL, NAHT, UCAC and Voice as well as NUT.
Read the NUT's evidence and supplementary evidence to the School Teachers’ Review Body (STRB) which calls for the Review Body to recommend a significant increase in teacher pay levels in the light of the current evidence on teacher pay, teacher supply and teacher morale.
The STRB report was published on 10 July. It recommended a 1% uplift to the minima and maxima of all pay ranges and allowances other than the main pay range, where a 2% uplift to the minimum and maximum was recommended. You can see the NUT response to the announcement here. A joint union response to the STRB report, produced by NUT, ATL, ASCL, NAHT, UCAC and Voice is also available by clicking here.
