The ‘churn’ of teachers moving between schools has nearly doubled between 2011 and 2015 with London experiencing the highest proportion of teachers moving between institutions, new government figures  show.

The number of teachers in a year who move to another state funded school is estimated to have nearly doubled between 2011 and 2015, from 10,400 to 18,200 entrants to primary schools and from 8,300 to 16,500 entrants to secondary schools.

In 2015, teachers moving between job was the biggest source of new recruits to schoos.

In primary, the natinal “mobility rate” rose from 4.9 per cent in 2011 to 8.1 per cent in 2015. Outer London is the worst affected, with a school-to-school mobility rate of 9.6 per cent.

In secondary, the national rate of school-to-school mobility increased from 3.9 per cent to 7.9 per cent in the same period of time. The highest rates in 2015 were in Inner London (9.8 per cent), Outer London (8.5 per cent), the South East and Yorkshire and the Humber (both 8.5 per cent.)

The figures come as concerns continue about teacher recruitment and retention and the effect of workload on staff.
