But try secretly filming the disaster that is State education and hear the screams from the NUT.
Over a period of about six months, she went into 18 schools in London and the north of England as a supply teacher and secretly filmed in six of them.
She says she saw chairs being smashed, pupils fighting in class and that she was sworn at by pupils and was falsely accused of touching them.
Other bad behaviour by pupils included verbal abuse, general rowdiness and the use of mobile phones or CD players.
Teaching sometimes became impossible, she said.
Five's senior programme controller, Chris Shaw, said: "I hope this film will open every parent's eyes to the chaos that reigns in many classrooms and makes meaningful teaching almost impossible."
The National Union of Teachers condemned the programme, saying it was not right to film children secretly.
General secretary Steve Sinnott said: "Low-level disruption is a significant problem in our schools.
"We do not need underhand methods for a cheap documentary to expose the problem."
The union said the programme's methods were unacceptable and would not improve children's behaviour.
