Techniques and approaches for collecting evidence and assessing elections.
Election observation missions use different methodologies depending on their goals, scale, and context. Combining the right methods helps improve evidence quality, strengthen analysis, and support more credible reporting.
What this section covers
This section introduces the main observation approaches used in missions and shows how each method contributes to stronger evidence gathering.
- Stationary observation for depth
- Roving observation for breadth
- Sample-based observation for statistical confidence
- Social media monitoring for digital tracking
Core observation approaches
Different mission objectives require different tools. These four approaches are commonly used to generate detailed, wide-ranging, statistically grounded, and digitally informed evidence.
Stationary Observation (STOs)
Stationary observers remain at one assigned polling station for the full electoral day. They document opening procedures, voting, closing, and counting, providing continuous and detailed coverage of a specific location.
Roving Observation
Roving observers cover multiple stations within a defined area, helping missions build wider situational awareness. This method is useful for spotting systemic issues, recurring incidents, and crowd or security trends.
Sample-Based Observation (SBO / PVT)
Sample-based approaches deploy observers to a statistically representative sample, allowing missions to make generalizable findings. Parallel Vote Tabulation and quick counts rely on rigorous sampling design and strong observer training.
Social Media Monitoring (SMM)
Social media monitoring tracks online narratives, misinformation, hate speech, and fast-moving rumours. Teams document posts, screenshots, and metadata, and work with the ESR to verify and contextualise digital reports.
Why combining methods matters
Missions are often strongest when they use more than one methodology, balancing detail, reach, statistical reliability, and digital verification.
