Why Choose Us

SNT trainers score an average of over 90% on the three main areas of:
  • Ability to teach
  • Technical knowledge
  • Answering questions
“Excellently presented by a very knowledgeable and enthusiastic trainer.” P.D. General Dynamics

We limit our maximum class size to 8 delegates; often we have less than this. This ensures optimal interactivity between delegates and instructor.
"Excellent course. The small class size was a great benefit…" M.B. IBM

We write our own courses; courseware does not just consist of slides and our slides are diagrams not bullet point text. A typical chapter provides clearly defined objectives with a chapter overview, slides with text underneath, a quiz at the end to check the learning of the students. Hands on exercises are at the end and are used to reinforce the theory.
