How to Appoint a GLP Study Director
Establish the single point of study control that good laboratory practice is built around.
What a how-to is not
A how-to is SPEQ’s practitioner method, not a procedure. It does not replace your own SOP, it is not a validated approach, and the judgement calls in it belong to your quality unit.
Good laboratory practice organises a nonclinical safety study around one named individual who carries overall responsibility for its conduct and for the final report. That single point of control is the structural feature that distinguishes it from every other laboratory quality system, and the appointment is not administrative: it is the mechanism by which a study becomes attributable to a person rather than to a department.
- 1
Appoint one director for the study, in writing, before it starts
The appointment is documented and dated, and it names one individual — not a role, not a team. A study whose director was appointed retrospectively, or is identified only by job title, has no demonstrable point of control for the period before the record exists.
- 2
Confirm the appointee has the training, education and experience the study needs
The qualification is study-specific rather than generic. A director qualified for one study type is not automatically qualified for another, and the training record must show the basis for the appointment at the time it was made.
- 3
Establish that the role carries authority, not only accountability
The director approves the study plan, controls its amendments, and can stop the study. Where the organisation reserves those decisions to a manager, the director carries responsibility without the ability to discharge it — which is a finding about the structure, not about the person.
- 4
Define the interface with the quality assurance unit
Quality assurance is independent of the director and reports its findings to management as well as to the director. Conflating the two, or having quality assurance report only through the director, removes the independence the arrangement exists to provide.
- 5
Document the replacement procedure before you need it
Where a director leaves mid-study, the replacement is appointed and the change recorded promptly, with the date of transfer. A gap between the departure of one director and the appointment of the next is a period the study cannot account for.
- 6
Sign the compliance statement at the end and mean it
The final report carries the director’s dated signature confirming the study was conducted in compliance and identifying any deviation and its effect. That signature is the whole appointment resolving into one document — it is not a formality, and a director who cannot defend it should not sign it.
- !The role assigned to a job title or a team, so no individual is attributable for the study’s conduct.
- !Appointment documented after the study started, leaving the opening period without a point of control.
- !Responsibility assigned without the authority to amend the plan or stop the study.
- !A mid-study handover with no dated transfer, leaving a gap nobody is accountable for.
How to Appoint a GLP Study Director: frequently asked questions
Common questions on appoint a glp study director.
Why does good laboratory practice insist on a single named director?
Because the system is built on attributability. A study conducted by a department can be defended by nobody in particular; a study with a named director has one person who approved the plan, controlled the deviations, and signs to say what happened. Every other GLP requirement hangs off that.
Can one person direct several studies at once?
Yes, provided they can discharge the responsibility for each. The constraint is capacity and qualification, not number. Where a director cannot describe the current state of a study they are named on, the appointment has become nominal, and that is what an inspection tends to surface.
What is the relationship with the quality assurance unit?
They are independent of each other by design. Quality assurance inspects the study and reports to management as well as to the director, so that problems have a route that does not depend on the person responsible for the study agreeing they are problems.
