  • "Sue was an excellent trainer and a nice person to be trained by too. Clearly has a thorough and comprehensive knowledge of not only the course but the whole discipline."
    Joe, APM PMQ course
  • "The use of whiteboards, real time example, breakout room and attempting the questions after every topic was really helpful. The enthusiastic tutor, made the course better."
    Anon, PRINCE2 Agile course
  • "The ideas and techniques learned in the course has changed my vision towards project management. It taught me various methods which I can apply in my career. I managed to learn new aspects of management cycle which I was unaware of. The course was very useful to me."
    Pawan, PRINCE2 Agile course
  • "I thoroughly enjoyed the course and got a good deal of useful information from it. I have carried out projects throughout my career, and a few years ago took the APM Project Management Qualification (PMQ), but carried out projects using my own methods. PRINCE2 is great in that it sets out a methodology for carrying out project management, and is the most widely recognised in the UK. Adding agile was the icing on the cake."
    Lara, PRINCE2 Agile
  • "Dhaliwal Narinder our trainer was excellent, adding insights from her vast experience to enhance our learning. We have tried Agile and Project Management separately, now i have the opportunity to try both again in my Faculty. Receiving this course online whilst locked down was perfect."
    Kevin, PRINCE2 Agile course
  • "The course was interesting and interactive, though a lot of information needed to be crammed in and consumed. Having done an Agile course a few years ago, this course helped to reinforce what was previously learned and put a project management theme to it. The instructor was very knowledgeable and explained the theory very well. The other participants were engaging and helped make the course interesting through the sharing of question and answer sessions to the relationship of past experiences."
    Ted, PRINCE2 Agile course
  • Experienced and well qualified training staff provide excellent support and are committed to improving trainees' experience.
  • "The pass rate is delivering more competent well-rounded, 'turn their hand to anything' engineers. All of the main courses delivered by MKC achieve notably higher success rates than the corresponding courses delivered by either Further Education (FE) or private training providers'."
    KPMG
  • MKC is seen to be strongly in line with acknowledged approaches to good practice in vocational education and training.
    Dr A Lahiff University College London Institute of Education (IoE)
  • The Open & Honest partnering approach will save MoD an average of 25% on previous training costs.
