CIWM Certificate in internal workplace mediation


Accredited workplace mediator training (over 5 days). Equipping and accrediting people as mediators in their workplace.

This is a 5 day course, delivered across two weeks. The dates are:

Week One: 9th, 10th and 11th November 2022

Week Two: 17th and 18th November 2022.

Business need

Differences between individuals at work can lead to lack of focus on the job, grievances, absences, loss of valuable employees and sometimes Employment Tribunal claims. The cost in terms of time, money and stress on managers and employees is considerable. Mediators work with those in conflict to help them find and agree their own solutions.

This training course is accredited by NCFE, a trusted and recognised awarding organisation, so the certificate gained meets a consistent standard. The training and delegate assessment are externally verified by NCFE and quality assured. Successful learners will be awarded the Acas Certificate in Internal Workplace Mediation.

Delegates are assessed through their performance in role play activity on the course and by their written responses to 6 questions based on the five units of the course. Responses must be sent to their tutor no later than 6 weeks after receiving the questions. Get more information on this course.

Suitable For

Managers at all levels, Human Resource professionals, In-company lawyers, employees, employee representatives and anyone interested in managing conflict more effectively in their workplace.

This course is not suitable for delegates who plan to work as freelance mediators outside of their own workplace.


This course provides training and accreditation for people to:

  • Become internal mediators in their workplace
  • Gain accreditation if they are already workplace mediators
  • Develop better conflict management and interpersonal skills for day to day relationship management

The course consists of 5 units and will take place over 5 days. The course covers the nature of workplace conflict, when workplace mediation is and is not appropriate, skills, strategies, behaviours and knowledge needed to be an effective workplace mediator as well as management and evaluation of the mediation process.
