"I’ve found it very useful and the course was very well put together and delivered."
"Will urge others at my work to apply for same course due to the relevant content and way it was moulded to our needs."
This structured course uses Instructor Led Training to provide the best possible learning experience. Small class sizes ensure students benefit from our engaging and interactive style of teaching with delegates encouraged to ask questions throughout the course. Quizzes follow each major section allowing checking of learning. Hands on sessions are used throughout to allow delegates to consolidate their new skills.
