The inadequacies and inequalities in our education system clearly agitate playwright John Godber.

As well as Teechers, he wrote a number of episodes of the TV series Grange Hill. Teechers is probably autobiographical. He was, briefly, a drama teacher before taking over the much more rewarding Hull Truck Theatre Company.

Teechers is a thoughtful, funny and occasionally moving play performed by three young actors who tackle multiple roles charting the progress through a downmarket secondary school of a young drama teacher who changed children from no-hopers to young people with self-respect and at least a modicum of ambition.

There is much adolescent vernacular in the language, but it is so firmly in context it is hard to find it offensive.

In Stuart Marno as Salty, Alexis Ritchie as Gail and Abigail Newton as Hobby, director David Thompson found three talented actors, who switch between roles as pupils and teachers with remarkably well-honed skills.

Stuart Marno in particular is one to watch. He has expressive body language and an impressive voice range.

One slight niggle is that occasionally the music was bit too much competition for all the voices and oddly when a teacher was complaining about too much racket coming from the drama class, there was no noise at all.

You can join the class at the Wharf until Saturday.
