Tinker, tailor, teacher ... spy
Jet-setting, espionage and national security are not usually associated with a career in the classroom, despite the constant battle to make lessons more exciting.
But all that looks set to change. MI5 bosses are hoping that teachers will switch to protecting Queen and country as they target school staff in their latest recruitment drive.
The secretive agency, which aims to "frustrate" terrorism, detect foreign espionage and stop other countries creating weapons of mass destruction, believes teachers have the skills needed for a career at the heart of intelligence gathering.
An advertisement placed in The TES says teachers' daily experience of dealing with people means that they could make "ideal" candidates for training to become operational intelligence officers.
But those at the chalkface might not be overly tempted by the money. The salary is Pounds 35,425, depending on skills and experience - about the same as a secondary teacher who has been in the job for some time.
"Your experience of dealing with people means you can build trust and relationships with all sorts of individuals, which makes you the ideal candidate for developing a career securing the information we need to protect national security," the advertisement says.
Operational intelligence officers are at the heart of the UK's network of spies.
They are responsible for developing contacts or informants, and must build a rapport quickly with a wide range of people.
Good communication is essential. The officers have to collect information from spies, or agents, and then write reports for their security bosses.
MI5 says self-awareness and sensitivity are essential. Officers will be based in London but will often operate away from the office and work antisocial hours.
A Home Office spokeswoman said: "There are a wide range of career opportunities available with MI5.
"The organisation advertises in a range of media, including local, regional and national newspapers, trade publications and online media in order to attract a diverse range of candidates who may have the right skills and experience."
