After the war was over, the government made some very big changes. One of these was to make all children stay at school until they were 15 (it is now 17). Some children passed the 11+ exam and went to grammar schools, others went to technical schools or secondary modern schools.
Before the war you had to pay for treatment if you were ill. From 1948 the National Health Service (NHS) was formed and then seeing the doctor or going to hospital was free.
