Capturing long-term change requires tracking beneficiaries over time. We design and implement longitudinal studies that revisit the same individuals, households, or communities at multiple intervals post-intervention.
These studies provide powerful insights into sustainability, delayed effects, and life course transitions.
Our approach involves panel retention strategies, mobile follow-ups, and ethical protocols for sustained engagement. Longitudinal data enables better understanding of both immediate and evolving impact, providing donors with crucial evidence to inform scaling, redesign, or exit strategies.
