Military cadet forces should be set up in schools to restore discipline and control unruly pupils, a teaching union will hear this week.

Voice, which has 38,000 members, will discuss a motion that it should welcome the establishment of cadet units in state schools.

This clashes with the stance of the NUT, the biggest teaching union, which voted in March to oppose military recruitment campaigns in schools. One teacher told that debate that military cadet forces should be barred from schools because they were used for recruitment.

But two months later, a report commissioned by Gordon Brown said more cadet corps should be set up in schools, and recommended the inclusion of lessons on the Armed Forces’ role in society in the national curriculum. It also said more military personnel should visit schools.

This has found favour with Peter Morris, the retired teacher who is making the latest proposal.

He will tell the Voice annual conference on Wednesday that a military presence at school would foster patriotism, integrity, loyalty and courage.

“Society as a whole is becoming less disciplined,” he is due to say. “As a profession, we continually complain about the indiscipline of pupils. The establishment of cadet units will, I am sure, help with discipline in our schools. They will give pupils an insight into the role of the armed forces.”

Mr Morris will tell the event in Northamptonshire that having a cadet force on site will help prevent low-achieving pupils from dropping out of school and drifting into crime.

He is expected to say: “I have seen a pupil lift a computer monitor above his head ready to throw it at a teacher. I have seen pupils barring the way of a teacher along a corridor.

“Pupils are well aware of their rights these days and exercise those rights to the full, often leaving teachers with little or no power to restore discipline.”

An IT teacher for 15 years, Mr Morris was formerly a policeman, but retired after suffering assault while on duty.

In an apparent allusion to the NUT stance, he will tell delegates: “No doubt left-wingers in our profession will try to sabotage the government’s plan for cadet units, just as many colleagues in another teaching union recently voted to ‘actively oppose’ the army making visits to schools.

“The structure which is lacking in the lives of so many young people today is offered by cadet units, and there is nowhere better to house these cadet units than in schools.

“These units can work well for high achievers as well as those who will drop out of school early - with the consequential risk of falling into a life of crime.”

Mr Morris will tell the conference that cadet forces will “inculcate some of the values which we, as a society, are missing: self discipline, self-reliance, loyalty to one’s comrades, to one unit and to one’s country, courage, respect and integrity.”

Voice, formed from what was the Professional Association of Teachers, and other unions, counts teachers, lecturers, heads, support staff, nannies and childcare professionals among its members.

Speaking to The Times, Mr Morris said many discipline problems in the classroom were caused by having mixed-ability lessons, during which both high and low achievers became bored.

He said cadet units could engage some pupils by giving them a sense of purpose and achievement, and showing them how a career in catering or music could be pursued within the military.

They could also be used to help schools provide after-hours activities. The Government wants all schools to become “extended” by opening from 8am to 6pm.

Ed Balls, the Schools Secretary, said at the time of the report to Gordon Brown: “I believe combined cadet forces can make a huge difference to the young people who join them and the schools and communities in which they are based.”
