Is this for Metrology Labs, or Testing Labs, or Pharmaceutical Labs, or a single program for any "lab"?
Different disciplines require very different knowledge, but since this is a very general question, I'll give a general answer. All modern Quality Assurance tends to lean toward statistics, such as Statistical Process Control, Uncertainty, etc. Understanding Quality Systems is also a universal requirement.
Other than statistics and quality systems, the needs vary greatly for each type of lab, and I'll need more information.
