What is it? Why is it important?

In a study, staff qualifications and ensuing responsibilities must be clearly defined and documented.


Staff qualifications and responsibilities can be documented in:

  • A CV (e.g. education / further education, vocational trainings)
  • Training certificates (e.g. GCP, lMP/IMD handling, data entry into the study eCRF)
  • A job description, which is an agreement between employee and line manager regarding employee duties and responsibilities
  • A study delegation-log, specifying staff duties and responsibilities within a given study
  • An organigram, where the structural organisation of a study team is depicted, including communication and reporting lines


Depending on study design and complexity additional requirement may apply, such as:

  • Selective expertise and qualifications (e.g. handling of complex machinery)
  • The recruitment of external service providers (e.g. laboratories)
  • The need for extensive staff trainings

What do I need to do?

As a SP-INV or Site-INV, file the following qualifying documents in the TMF and/or ISF of your study:

  • Study staff CVs
  • The study delegation log
  • Study applicable:
    • Training documents (e.g. study protocol, IMP- and sample management, SOPs, WIs)
    • Certificates (e.g. GCP-training, study applicable training certificates such as laboratory training, IMP/MD handling)
  • If applicable, study relevant job descriptions


Ensure CVs, training logs and job descriptions are up-to-date, personally dated and signed.


Staff expertise during study planning and conduct requires both medical and clinical expertise, including know-how regarding the special demands needed for clinical research.


Evaluate staff resources based on:

  • Know-how:
    • What type of skills are needed for the planned study?
    • Does staff have the required qualifications based on education, further education, and vocational training?
    • Which qualifications are missing?
    • Can staff be trained or must specific study tasks be outsourced?
  • Availability: Does staff have sufficient disposable free time to acquire required skills and expertise?
  • Budget: How will the requirement for qualified study staff affect the overall study budget (hiring of experts, staff education and trainings)?
