This simple observation carries a profound implication: the quality of a clinical trial depends entirely on the qualifications of the individuals conducting it.

Consider what happens when this principle is violated. A study coordinator without adequate training misinterprets eligibility criteria and enrolls a participant who should have been excluded. A pharmacist unfamiliar with investigational product handling compromises the cold chain. A data manager without understanding of database validation allows errors to propagate undetected. A biostatistician unfamiliar with the therapeutic area selects an inappropriate analysis method. In each case, the failure traces back to someone performing a task for which they were not adequately prepared.

ICH E6(R3) Principle 5 addresses this directly. Sub-principle 5.1 states that individuals involved in a trial should be qualified by education, training, and experience to perform their respective tasks. This is not an abstract aspiration. It is a regulatory expectation that shapes how trials are staffed, how responsibilities are assigned, and how qualifications are documented.
