You have reviewed the capabilities deck. You sat through the demo. The cost per complete is competitive, the panel size sounds impressive, and the account executive seems genuinely nice. And you are about to sign a contract that will determine whether your next study produces insight you can defend or data you will be quietly re-fielding in eight weeks. These nine questions expose the gap between what a recruiter claims and what their system actually produces.
1. Walk me through your participant verification methodology step by step, not the marketing version
A recruiter with a real verification system answers immediately, specifically, and in operational terms. They describe the sequence of layers, the behavioral tests applied, the human review step, and the documentation generated at each stage. A recruiter without a real system generalizes, uses marketing language, and circles back to something about screener design.
2. What is your documented show rate for the last 24 months and can you produce that report right now?
Not a claimed show rate. A documented show rate report covering actual studies over the last two years, available to share immediately. The recruiter tracking this data has built accountability around it. The industry average is 64 percent. If the number they show you is not meaningfully above that, ask what specific operational changes they made to improve it.
3. What is your professional respondent detection rate per study?
The recruiter with a real detection system knows their rejection rate because they are actively measuring it. They can tell you how many participants they screen out per study after initial qualification. The recruiter who does not track this number does not have a detection system. They have a screener. Those are not the same thing.
4. Who is the specific PM who will own my study and what is their direct line?
Not the account executive. Not the team. The named dedicated project manager personally responsible for your study from kickoff through completion. Get their name, direct phone number, and email before the contract is signed. If the recruiter cannot name a specific PM at the contract stage, you will be working with whoever is available when your study becomes active.
5. What time does my PM send the daily status update on an active study?
The answer should be 3 PM. Every day. Without you having to ask. If the answer contains the words typically, usually, when there is something to report, or as needed, that is a reactive communication standard. The difference between proactive and reactive communication is the difference between catching a problem at 7 AM when backfill is possible and discovering it at 9 AM when it is not.
6. Describe your backfill protocol when a participant no-shows the morning of fieldwork
Specifically who calls you, at what time, how many pre-qualified backups are in the pipeline, how fast can a replacement be activated. A recruiter with a real backfill system answers all four parts immediately because the protocol is documented and practiced. Commitment is not a protocol. Before you sign, you want the protocol.
7. What five documents can you produce per participant for Legal review within 24 hours?
The five documents: verification attestation, dual screening audit trail, condition-specific verification record, chain of custody record, and data retention commitment. Ask your recruiter to name all five without prompting. A recruiter who has built the system to generate them names them immediately. A recruiter who has not asks what you mean by verification documentation and you have your answer.
8. Is your panel proprietary or accessed through a third-party aggregator?
A recruiter with a proprietary attributed panel owns the participant relationships, controls the verification standard, and can provide attribution data showing participant history. A recruiter accessing a third-party aggregator has limited control over verification and limited ability to guarantee cohort quality. Ask for attribution data on your last study cohort as a demonstration.
9. What is your experience specifically with condition-verified health research in a regulated CPG category?
GLP-1. Supplements. OTC. Functional food. These categories sit at the intersection of consumer research and medical category substantiation. Ask your recruiter to describe a specific study in a regulated health category, the verification methodology they applied, and the documentation they delivered. If their most relevant experience is in food and beverage without condition-specific health components, they are not the right partner.
How to use these questions
Print this list. Bring it to your next vendor call. Ask every question in this order. The recruiter whose answers are specific, immediate, and operational across all nine is worth signing with. The recruiter whose answers contain the words ‘typically,’ ‘we generally,’ or ‘it depends’ more than twice is telling you something important about what your study will look like when something goes wrong.
