Employees will be able to choose from 27 qualifications that will cover chainsaw and related operations.
A City & Guild statement said the new qualifications take into account recent changes to the National Occupational Standards, and will offer "greater flexibility for candidates and a more structured and logical career progression."
It added that the qualifications would be suitable for all skill levels.
All of the new chainsaw qualifications will continue to be offered as "independent assessment", meaning an independent assessor, who has not been involved in training the candidate, will carry out the assessment.
But some of the new associated qualifications can be awarded via a new assessment approach called "integrated assessment", which means a qualified trainer/assessor that has provided instruction to the candidate can also carry out the assessment.
This assessment takes place at intervals after each period of training and the candidate must be informed when formal assessment is taking place and when it ends.
The existing City & Guilds qualifications, which are the industry standard will still be available for the next six months."
