“Research included in another paper on deprivation and education published by the Department for Children, Schools and Families in 2009 found that moving between secondary schools, especially after the start of year 10, has a particularly negative effect on exam performance at age 16. It said: ‘The average point score is depressed by more than 20 points for pupils who are mobile during years 7, 8 or 9, and by more than 70 points for those pupils who join the school after September in year 10. The former effect is similar in magnitude to that of being eligible for FSM, whilst the latter effect is greater than the effect of having a statement of special educational needs.'”(more)
