Teachers (Pay) Mr. Deakins asked the Secretary of State for Education and Science what is the average annual increase in teachers' earnings as a result of incremental drift. Sir Keith Joseph Between April 1979 and April 1984 the average salary of teachers in maintained nursery, primary and secondary schools in England and Wales is estimated to have risen by 5ยท1 per cent. as a result of incremental drift. The annual average increase over the period on this account is therefore about 1 per cent. Mr. Deakins asked the Secretary of State for Education and Science why the Burnham committee has not replaced its offer of a 4 per cent. pay incease with an offer of a flat rate amount per teacher. Sir Keith Joseph This is a question not for me but for the Burnham Primary and Secondary Committee.
