Why Choose Us
SNT trainers score an average of over 90% on the three main areas of:
- Ability to teach
- Technical knowledge
- Answering questions
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.
