Trinity Mirror and Northcliffe Newspapers are teaming up to launch a new sub-editing diploma to help battle a shortage of skilled production journalists.

The diploma, which involves a full training programme, is being run for Northcliffe Newspapers by the editorial training arm of Trinity Mirror.

It is based on a similar programme launched three years ago by Trinity Mirror, and aims to bring new talent into the industry to specialise in all elements of newspaper production journalism.

The decision is the result of a project led by Colin Davison, Northcliffe editorial adviser and MD of the group's Gloucestershire Media division, which looked at how best to tackle the problem of a sub-editor shortage.

Colin said: "The ambitious programme directly addresses the need to attract talented individuals who will particularly specialise in production skills, without neglecting the need to acquire experience as reporters."

An introductory programme begins in June, with the full 18-month scheme launched from September.

Trainees will spend several weeks developing their skills and knowledge in the classroom before returning to host newspapers. They will then undergo distance learning work and assignments.

The programme ends with a series of assessments and examinations which candidates must pass before they are acknowledged as senior production journalists.

Tony Johnston, head of editorial staff development for Trinity Mirror said: "We are delighted to be able to provide this high-quality, tailored training package to the Northcliffe titles.

"The training programme we have established in Trinity Mirror has provided a steady stream of highly skilled sub-editors to our newspapers.

"I am confident that we can do the same for Northcliffe and we very much look forward to working with them."
