Research participant recruitment brief template: write down what your recruiter can't guess

A good research participant recruitment brief template lets someone else find your participants without quietly changing your study. It does that with one split: experience a participant must have, kept apart from variation you would like to cover. Below is a working brief to copy, filled in for a made-up study of returns processing at small online retailers.

Essential experience makes someone able to answer the question. Useful variation lets you compare different contexts. A preference with no connection to the research should never become an exclusion rule. (The example criteria are illustrative, not findings about retailers or a recommended sample.)

1. Start with the decision the study serves

Tell the recruiter what the team needs to learn. A list of titles, company sizes and dates is not a brief.

For the made-up study: "We want to understand how a returned item moves from receipt to a decision about restocking or another disposition, especially when more than one team participates."

Now the recruiter can see why a warehouse operator might fit and a senior executive with no recent involvement might not. Still name who decides unclear cases.

GOV.UK recommends written recruitment instructions, and checking the resulting screener against them.

2. Sort the criteria into three groups

Essential: The participant has personally handled the part of the workflow under study within a relevant period. Choose the period based on the task, not a default recency rule.

Coverage: Operating contexts that could change the workflow. In the example, teams using their own storage space and teams working with an outside fulfillment provider.

Not required: A particular job title, a positive or negative opinion, use of your preferred tool, or willingness to buy your product, unless the study specifically needs that condition and says why.

This split stops recruiting convenience from redefining your audience. (The easiest people to book are not always the people you meant.)

3. Copy the working brief

Replace every placeholder before you hand it over. "To be filled in" is a planning gap, and a recruiter should not have to improvise it.

4. Say what the participant will and won't do

State whether the session is a discussion, an observation, a prototype test or a mix, and what preparation, equipment and materials it needs.

In the example, the person discusses a recent returns workflow without showing identifiable customer information. If the study later moves to screen sharing, update the participant information before asking for it.

The Home Office recruitment guidance puts the project purpose, timing, incentives and a contact person in the brief, and stresses voluntary participation. Never frame attendance as an obligation from a manager or business relationship. Declining should be clearly fine.

5. Tell the recruiter how to verify fit

Give one or two open factual prompts for each essential criterion. "What part of returns processing did you personally handle most recently?" tells you more than "Are you a returns expert?"

Add interpretation notes. An answer about receiving items directly could fit the receiving perspective. An answer about approving the overall vendor contract may suit another study, but it does not show the operating experience you need.

Do not ask the recruiter to judge whether the participant agrees with your product premise. A smooth existing process is relevant evidence too.

A screener establishes likely fit. It does not guarantee identity, competence or the truth of every claim.

6. Review the first candidates before recruiting more

Check a small first set against the written criteria. Read the actual qualification notes instead of trusting a "qualified" label.

For each poor fit, find the exact mismatch. Did the brief leave out a responsibility? Was a term misunderstood? Did the screener ask about familiarity instead of direct participation? Fix that cause before sourcing a larger group.

If your own criteria were wrong, change the brief openly. Record the version and decide whether already-booked participants are still useful. Do not pretend the new criterion was always part of the study.

7. Agree how exceptions and replacements work

Decide in advance how to handle cancellations, uncertain eligibility, unavailable formats and missing coverage. A replacement should meet the criteria for the open slot, which is a different thing from being free at the same time.

In the returns example, swapping a receiving operator for another purchasing manager may add a session and still leave the same gap in the evidence.

Keep participant information to what the team needs, and name who gets access to recruitment notes and what happens to them afterward.

8. Use the brief again during analysis

Compare the sample you got with the coverage you intended. If a fulfillment arrangement or role is still missing, say so in the findings.

Before recruiting starts, ask the recruiter to explain the qualifying experience, the exceptions and the known gaps back to you. If their version matches yours, the handoff worked.
