When to Use
Baseline design is the right approach when you need to establish a clear starting point for measuring change. Use it when:
- Setting indicator targets: Design teams often lack adequate information to confidently propose specific targets during proposal writing. Instead, indicator targets should be set upon completion of a project baseline study and included in the program's Indicator Plan.
- Measuring program impact: You need to compare endline conditions against initial conditions to assess whether your intervention produced change.
- Informing project adaptation: You want baseline data that directly informs critical decisions during implementation, not just donor reporting.
- Meeting donor requirements: Donors like USAID, CRS, and FCDO require documentation of baseline values in the Indicator Performance Tracking Table (IPTT) or donor equivalent.
- Longer-term projects: For projects 18+ months, conduct a baseline in the first 6 months; for shorter projects, conduct baseline prior to start or no later than 3 months into implementation.
Baseline design is less useful when:
- Projects are very short: Baseline values documentation is not required for projects less than three years in duration.
- You only need routine monitoring: For ongoing activity tracking, routine monitoring data collection follows a different workflow.
- Rapid emergency response: For immediate emergency response, a rapid needs assessment with a different, faster methodology is required.
| Scenario | Use Baseline Design? | Better Alternative |
|---|---|---|
| New project measuring change over time | Yes | — |
| Setting indicator targets | Yes | — |
| Short-term project (<3 years) | Optional | Routine monitoring |
| Emergency rapid assessment | No | Rapid Needs Assessment |
| Post-distribution monitoring | No | PDM workflow |
| Understanding unpredicted outcomes | No | Outcome Harvesting |
How It Works
Baseline design follows several core principles that distinguish it from other data collection activities:
Decision-utility first. Every data point collected must serve a specific, identified decision. If you cannot articulate which specific project decision each indicator will inform, question its necessity. This principle prevents the common dysfunction of data-rich but insight-poor baselines that collect excessive, non-essential data.
Count the burden. Collecting data is not free. Every indicator added to a baseline survey represents costs in terms of time, money, and human resources. Assess the burden (time, cost, complexity, participant fatigue) of collecting each data point. If the burden outweighs the value derived from informing a critical decision, challenge or discard the indicator. This is a core application of the burden-consciousness principle.
Trace to structure. Ensure data collection aligns with project logic, defined indicators, and any relevant structural requirements (e.g., donor modules). The baseline should support subsequent analysis and reporting, not create data that is difficult to code and analyze.
Comparability is key. Design baseline and endline methods to be as identical as possible to enable valid comparisons. Document any necessary deviations. If baseline and endline use different methodologies, tools, or definitions, comparisons become meaningless.
Baseline and endline are not evaluations. Baseline and endline studies are not evaluations themselves, but an important part of assessing change. They usually contribute to project/programme evaluation (e.g., a final or impact evaluation), but can also contribute to monitoring changes on longer-term projects/programmes.
Key Components
A well-constructed baseline design includes these essential elements:
- Decision identification: A documented, prioritized list of key project decisions that the baseline data will inform. This moves beyond broad categories to precise questions about what information is needed for each decision.
- Indicator selection: A lean, documented list of essential, decision-linked indicators. Each selected indicator should be directly linked to a prioritized decision, with the burden of collecting data for each indicator demonstrably justified by its decision-relevance.
- Data collection methodology: The most appropriate and cost-effective methods for collecting each data point (e.g., household surveys, key informant interviews, focus group discussions, direct observation, secondary data review). Methods should be clear, concise, unambiguous, and culturally sensitive.
- Sampling strategy: A representative sampling frame with appropriate sample size calculations, respondent selection procedures, and geographic coverage. For indicators requiring statistically sound data, ensure representative sampling and confidence intervals.
- Data collection tools: Draft tools (questionnaires, interview guides, checklists) that are clear, concise, easy to administer, and minimally burdensome for respondents and enumerators.
- Data management protocols: How data will be collected, entered, cleaned, stored, and secured. Specify data formats, validation rules, and quality checks.
- Quality assurance plan: Procedures for enumerator training, supervision, data verification, and spot-checking to ensure data accuracy and reliability.
- Informed consent procedures: Clear, simple, and culturally appropriate informed consent forms and verbal consent scripts that explain the purpose of data collection, how data will be used, confidentiality measures, potential risks and benefits, and the participant's right to refuse or withdraw at any time without penalty.
- Ethical approval: Formal ethical clearance from the designated review body before data collection begins.
Best Practices
Collect baseline data at the right time. Baseline data should be collected at the very beginning of a project or as soon after the beginning as possible. For longer projects (18+ months), conduct a baseline in the first 6 months; for shorter projects, conduct baseline prior to the start or no later than 3 months into implementation.
Link every indicator to a decision. For each proposed baseline indicator, ask: "If this data shows X, what decision will we make differently?" If you cannot answer this, the indicator is likely a candidate for removal or revision. This ensures the baseline serves as a dynamic tool for adaptation, not just a historical record.
Include baseline values or plans for all indicators. You must include baseline values or plans for baseline for indicators needing it. Just as every outcome needs at least one performance indicator, every indicator needs a target, and each target needs a baseline.
Incorporate baseline plans in project documents. Plans for Baseline need to be incorporated in the Donor Investment Plan (DIP), reflected in the Indicator Performance Tracking Table (IPTT), and clearly linked to indicators in the MEAL Plan that require baseline.
Set targets after baseline completion. Design teams will often not have adequate information to confidently propose specific targets. Instead, indicator targets should be set upon completion of a project baseline study and included in the program's Indicator Plan. Upon completion of a project baseline assessment, project decision makers set indicator targets. These targets should be informed by baseline results, the project timeline, human and financial resources dedicated to the project, and the permissiveness or difficulty of the context, including levels of uncertainty.
Select appropriate data collection methods. Select baseline data collection methods that align with and support the overall evaluation design, are appropriate for the given indicators, and meet donor requirements. Methods should be the most efficient and effective for gathering the required data while minimizing respondent and enumerator burden.
Document baseline values properly. Once the baseline value for an indicator has been determined, record the value and date collected in the 'baseline value' column of the Indicator Plan. Projects should document the baseline values in the Indicator Performance Tracking Table, or IPTT, or donor equivalent.
Collect baseline information before project activities begin. Baseline information for all indicators must be measured and reported prior to the start of project activities. This ensures you have a true starting point for measuring change.
Common Mistakes
Collecting data without decision utility. The most common failure is designing a baseline that collects data solely for donor reporting without a clear plan for how it will inform decisions. When every data point cannot be linked to a specific project decision, you've created a burden of excess that wastes resources.
Using different methodologies at baseline and endline. If baseline and endline use different methods, tools, or definitions, comparisons become meaningless. Design both time points to be as identical as possible to enable valid comparisons. Document any necessary deviations.
Skipping pilot testing. Rushing to deploy without pilot testing leads to major, costly errors in the field. A pilot test should systematically identify issues with tool clarity, flow, length, and cultural appropriateness before full deployment.
Underestimating ethical review timelines. Ethical review timelines can vary significantly and may require proactive follow-up. Underestimating the time required for review and approval leads to project schedule slippage.
Collecting baseline after project start. For projects where baseline is conducted after implementation has begun, you've already lost the ability to measure true initial conditions. Baseline information must be measured prior to the start of project activities.
Not documenting baseline values. Once baseline values are determined, they must be recorded in the Indicator Plan. Without proper documentation, you cannot track progress against targets or demonstrate change to donors.
Treating baseline as an evaluation. Baseline and endline studies are not evaluations themselves. They are important parts of assessing change and contribute to project/programme evaluation, but they do not constitute a full evaluation.
Examples
Agricultural Livelihoods, East Africa
A 5-year agricultural resilience programme in Kenya and Uganda developed a baseline design that explicitly linked each indicator to a critical project decision. The team identified five key decisions: which crops to promote for market linkage, what training types farmers need, what market access barriers exist, which farmer groups are most receptive to new techniques, and how to allocate resources. For each decision, they collected only the data needed to inform it. When mid-term monitoring revealed land tenure was the binding constraint (not seed availability as expected), the programme redirected resources accordingly. The baseline functioned as a diagnostic tool, not just a design artefact.
WASH, South Asia
A water and sanitation programme in Bangladesh designed baseline and endline surveys to be identical in methodology, tools, and sampling approach. This enabled valid comparison of health outcomes between time points. The evaluation found that behaviour change communication was responsible for 60% of health improvements, while infrastructure contributed 40%. Without the comparable baseline-endline design, this finding would have been invisible.
Protection, West Africa
A protection programme in Sierra Leone initially planned a comprehensive baseline with 80 indicators. Using a decision-first approach, the team mapped each indicator to a project decision and found that only 25 indicators directly informed critical choices. They collected the remaining 55 indicators as "nice-to-know" data through secondary sources where possible, reducing survey time from 90 minutes to 45 minutes and freeing resources for deeper analysis of essential data.

| Primary purpose | Measure initial conditions for change assessment | Immediate emergency response needs identification | General survey methodology |
| Timeframe | 4-8 weeks | Days to 2 weeks | Varies by scope |
| Depth | Comprehensive, decision-linked | Limited, prioritized | Varies by design |
| Sampling | Representative, statistically rigorous | Often purposive or convenience | Depends on objectives |
| Best for | Measuring program impact | Emergency response | General data collection |
| Comparison | Designed for baseline-endline comparison | Not designed for comparison | Depends on design |
Relevant Indicators
18 indicators across 4 major donor frameworks (USAID, CRS, FCDO, ECHO) relate to baseline design and use:
- Baseline documentation: "Proportion of indicators with documented baseline values collected before project start" (USAID)
- Decision linkage: "Percentage of baseline data collection linked to specific project decisions" (FCDO)
- Baseline timing: "Baseline assessment completed within 6 months of project start for projects 18+ months" (CRS)
- IPTT documentation: "Baseline values documented in Indicator Performance Tracking Table (IPTT)" (USAID)
