My daughter is just finishing year 3. For the second year running the headteacher is mixing up all year classes (there's about 60 pupils in each year). This is happening in all years in the school. It is difficult to find any systematic rationale put forward by her to justify this practice.
I understand that annually mixing up classes is increasingly common.
Does anyone know of any evidence to show that this is helpful to the children?
Any pointer towards any research, evaluation or evidence on this would be most appreciated.
Thanks
