How field data collection creates unique surveyor management challenges
In-person data collection relies on surveyors, often called enumerators, to administer surveys directly to respondents. These surveyors turn a questionnaire into a live interview, capturing data that informs research findings, program decisions, and policy choices. Because interviews happen in real-world conditions, data quality depends on more than form design. It also depends on consistent field execution, including how questions are asked, how consent is handled, and how responses are recorded.
A common operational reality is that principal investigators (PIs) and field managers are primarily office-based, while surveyor teams operate across dispersed communities, facilities, or remote geographies. Day-to-day oversight is often delegated to field supervisors on location, but even then, managers and supervisors cannot directly observe every interview or easily spot emerging patterns across large teams. When visibility is limited, small problems, such as rushed interviews, repeated nonresponse, or inconsistent probing, can compound quickly and affect a large portion of the dataset.
Supervisor scorecards are a practical way to close that visibility gap. They provide field supervisors, managers, and PIs with a consistent structure for monitoring enumerator performance during data collection, enabling early intervention and course correction while fieldwork is still underway.

Key KPIs field managers should track for effective surveyor management
Strong surveyor management starts with knowing which signals indicate that something may be going wrong in the field. The goal is not to “catch” enumerators. The goal is to detect issues early so supervisors can clarify protocols, provide coaching, or address operational constraints before they affect the final dataset.
Here are high-value KPIs to track per enumerator, along with what they can tell you:
- Interview duration
Interviews that consistently fall outside the expected duration range for a given survey may indicate rushing, skipped questions, or respondent confusion. - Drop-offs and incomplete interviews
A higher-than-expected drop-off rate can be caused by respondent fatigue, unclear consent scripts, challenging interview environments, or enumerators struggling to build rapport. It may also signal that the survey is too long or that question flow is confusing, which should be flagged to the PI or survey design team for review. - Item nonresponse (skips, “don’t know,” refusals)
Higher levels of item nonresponse may signal discomfort with sensitive topics, inconsistent probing, or unclear question wording. It can also reflect respondent context. For example, questions that require recall or records may legitimately produce more “don’t knows” than other questions. - Submission timing patterns
Submissions clustered at unusual times, such as many interviews appearing within a short window or with identical timestamps, can be a cue to review field workflows more closely. In some cases, this reflects operational constraints like connectivity delays or batched uploads. In other cases, it may indicate that interviews are not being conducted as expected, warranting follow-up to confirm field practices and reinforce protocols. - GPS/location consistency (when applicable)
GPS data can help assess whether interviews align with study design and field protocols. In some cases, clustered locations are expected (for example, facility-based surveys or centralized recruitment). Because GPS data is often used to support verification and interpretation of fieldwork conditions, location patterns that differ from expectations or lack a clear explanation may warrant follow-up.
Pro tip: Define expected KPI ranges before fieldwork begins so supervisors can act consistently rather than debate thresholds once data collection is underway.
These indicators are widely referenced in survey operations guidance from organizations such as the World Bank survey methodology resources and Innovations for Poverty Action research methods, both of which emphasize monitoring data quality while collection is still in progress.
Many teams rely on data collection platforms to make these KPIs easier to monitor during fieldwork. For instance, SurveyCTO’s monitoring views and data exports allow supervisors to review interview duration, completion status, submission timing, and enumerator-level patterns without manually inspecting every record.
How supervisor scorecards turn KPIs into actionable oversight
KPIs are valuable, but they only drive improvement when you review them consistently and connect them to actions. That is where a supervisor scorecard helps.
A good scorecard gives field managers and PIs a repeatable way to assess enumerator performance at a glance, track trends over time, and document follow-up actions.
A supervisor scorecard typically works best when it does three things:
- Summarizes performance in a single view
Instead of sifting through raw exports, supervisors can see duration, drop-offs, item nonresponse, and submission patterns together. This reduces review time and helps managers compare enumerators more fairly. - Highlights outliers without overreacting
Scorecards should emphasize trends, not one-off anomalies. A single short interview is rarely actionable, but repeated patterns are. When issues warrant a closer look, survey tools with auditing features can provide deeper visibility into how interviews unfold. For example, the research team at Laterite used SurveyCTO’s text audit data to analyze survey duration at the level of individual questions and modules. - Links metrics to follow-up actions
The scorecard is not just for reporting; it’s a management tool. It should make it easy to track actions such as coaching, refresher training, protocol reminders, or clarifying probing expectations when patterns, such as short interviews or high item nonresponse, appear.
This scorecard approach pairs naturally with other structured tools research teams already use. For example, many PIs rely on structured checklists to evaluate survey forms before deployment to confirm questionnaires meet project objectives, protect respondents, and function correctly. A supervisor scorecard extends that same discipline into field execution.
It also fits into broader surveyor preparation and support. Strong surveyor management builds on solid enumerator management practices, including recruitment, training, risk planning, and communication protocols.
Pro tip: Pick a review cadence and stick to it (for example, every 2–3 days early in fieldwork, then weekly). A predictable rhythm is often more effective than “deep dives” that happen too late.
What a practical supervisor scorecard looks like in the field
A scorecard does not need to be complex. In fact, simpler scorecards tend to be used more consistently. The best template is one that supervisors can review quickly, explain clearly to enumerators, and act on without creating extra administrative burden.
Below is a practical scorecard example you can adapt for your own surveyor management workflows.
Supervisor scorecard template
Enumerator details
- Enumerator name/ID
- Supervisor name/ID
- Location/cluster/assignment
- Reporting period (dates)
Productivity
- Completed interviews (total)
- Interviews per active day
- Comparison to team average (above / near / below)
Quality KPIs
- Median interview duration (min–max)
- Speed spikes count (e.g., interviews below a defined time threshold)
- Drop-off rate (% incomplete)
- Item nonresponse rate (% “don’t know”/refusals/skips)
Field integrity signals
- Submission timing notes (clusters of submissions within short time windows, identical or near-identical timestamps)
- GPS checks: repeated points, missing points, outliers
- Duplicate-like patterns worth review
Supervisor notes and actions
- Main observation (1–2 lines)
- Action taken (coaching, refresher training, review protocol, operational fix)
- Follow-up date and result (improved / unchanged / needs escalation)
This structure supports clear communication for situations when managers are office-based and surveyor teams are in the field. It gives supervisors and enumerators a shared reference point for performance discussions, while allowing PIs to identify fieldwork patterns without needing to fully review individual submissions.
Interviewer monitoring is widely recognized in survey methodology as a core component of quality assurance. For teams using digital data collection, platforms like SurveyCTO support this process by consistently attributing interviews to individual enumerators and, where appropriate, capturing integrity signals—such as GPS data—thereby making it easier to aggregate and review scorecard metrics during fieldwork.
Pro tip: Keep “Supervisor notes” short and specific (what you observed + what you did). Long narratives are harder to review later and less useful for tracking improvement.
Using supervisor scorecards to protect data quality during fieldwork
Surveyor management becomes difficult when field managers and PIs are physically removed from data collection sites. Without structured visibility into enumerator performance, issues can go unnoticed until it is too late to correct them. That is why a supervisor scorecard is so useful. It turns abstract data quality goals into concrete, trackable signals supervisors can review during fieldwork.
By focusing on a small set of meaningful KPIs and using scorecards to review them consistently, teams can identify problems early, support enumerators with targeted coaching, and protect the quality of the final dataset. When paired with strong preparation and clear protocols, scorecards help ensure that fieldwork quality is actively managed throughout collection, not only evaluated afterward.
