Children's Education

The education system in Britain was drastically affected by World War Two. Children were only in school until the age of fifteen, and legislation to extend the age was postponed when the war started. When the city bombings began, children and teachers were evacuated en masse to the rural areas, where the schools had fewer supplies and materials. The children who weren't moved now had no school, and lost the health tests and free food perks, as well as increasing the rate of hooliganism in cities. Then, as teachers started to get drafted to fight, the class sizes exploded, making any learning very difficult. Eventually, the school day had two be slit into a double shift system, where kids could only come in the morning or in the afternoon.
These problems were very difficult to avoid, as logistical snags will affect any type of mass movement of people. The British government should have enforced an evacuation of all children in the cities to avoid the problems created by the stragglers, and then invested the neccessary money to build the additional building needed for the schools. Then they'd be able to focus on the war without another unneeded distraction.
