The SIEL program is a six-year learning partnership between the UK's Foreign, Commonwealth and Development Office’s (FCDO) Evaluation Unit, Innovations for Poverty Action (IPA), and the Abdul Latif Jameel Poverty Action Lab (J-PAL). Running from 2024 to 2030, SIEL provides funding, resources, and technical capacity to help make FCDO's global programs and policies more effective by generating evidence-based insights through impact evaluations.
SIEL will generate evidence in four strategic areas: Growth, Humanitarian Assistance, Climate and Nature, and Conflict and Fragility, with cross-cutting themes on women and girls, technology and innovation, and migration.

Call for Expressions of Interest (EOI) | Round III
SIEL will focus on four strategic areas: humanitarian assistance, growth, climate and nature, and conflict and fragility. All FCDO staff are eligible to apply for impact evaluation funding and support through SIEL via semi-annual calls for Expressions of Interest. EOIs are due on Wednesday 30 September 2026 via this Microsoft Form. For more information about the application process, please visit the Strategic Impact Evaluation and Learning folder, under L. Evaluation in the EED library (open). If you are unable to access the folder or have any other questions, please reach out to our Help Desk at siel@poverty-action.org. |
How can SIEL help FCDO staff generate insights?
Read our Learning Agendas
SIEL's learning agendas were developed in consultation with FCDO staff and thematic experts to outline critical evidence gaps in SIEL's four strategic areas to spark robust impact evaluations of FCDO interventions through a centralized process. This is intended to guide future evaluation of FCDO interventions and to target research to understudied areas with high potential to inform FCDO’s work moving forward.
![]() | Humanitarian Learning AgendaGiven the rising need for effective humanitarian programs, it is important that existing evidence gaps are filled to best deliver on core objectives: 1) prioritizing humanitarian assistance to people in greatest need, 2) protecting the people most at risk, and 3) preventing and anticipating future shocks and building resilience. |
![]() | Growth Learning AgendaDespite significant investments in promoting economic growth, large evidence gaps persist across key areas that hinder effective policymaking and program implementation. These gaps span five key categories: 1) trade and market access for firms and workers; 2) government, regulation, and political economy; 3) access to capital; 4) entrepreneurship, business, and workforce development; and 5) green and sustainable growth. |
![]() | Conflict & Fragility Learning AgendaWhile the body of impact evaluations on effective strategies for preventing and responding to conflict and the drivers of instability has grown in recent years, important evidence gaps remain. These gaps are organized around four key categories: 1) anticipating and preventing conflict before it erupts; 2) ending conflict and building peace; 3) increasing stability in fragile settings; and 4) responding to emerging state security threats, including transnational and organized crime and violent and religious extremism. |
![]() | Climate & Nature Learning AgendaTransformative global action is needed to address the interlinked and existential challenges of climate and nature. Impact evaluations can help identify the most effective interventions, ensuring that climate and nature strategies are grounded in robust evidence. Nearly all areas of FCDO’s work can incorporate a climate or environmental perspective, underscoring the need for targeted evidence to advance this agenda. This learning agenda organizes sample research questions into three key themes: adaptation, mitigation, and nature. |
Apply for funding and support for evaluations
SIEL provides funding for a range of evaluation methods to assess FCDO’s programs and policies. FCDO staff are invited to apply for SIEL-funded research through a process coordinated by IPA, in consultation with FCDO’s Evaluation Unit.
FCDO teams can get tailored support from IPA and J-PAL staff as well as academic researchers to identify promising opportunities for evaluations.
What evaluation methods does SIEL support?
SIEL specializes in evaluations that use experimental or quasi-experimental methods to assess causal impact. Proposals are solicited through an Expression of Interest process for four research types:
![]() | Quantitative Impact Evaluations These determine the causal impact and cost-effectiveness of interventions by comparing randomly assigned groups, generating high-confidence insights. Impact evaluations can answer questions such as: How effective was this program? Who benefited most? Which components of the program worked or did not? |
![]() | Long-Term Follow-Ups To capture the sustained impact of FCDO-funded interventions, and potential unintended consequences (positive or negative) of an intervention that may only become apparent over time, long-term follow-ups provide insights into the enduring effects of a program beyond initial outcomes. |
![]() | Nimble Evaluations Quick, cost-effective randomized controlled trials (RCTs) that generally focus on outputs and shorter-term outcomes, nimble evaluations typically address operational questions (e.g. take-up, enrollment) and can leverage administrative data to reduce time and cost. For example, what is the most effective method for enrolling people in a training program? Which product features encourage farmers to buy rainfall insurance? |
![]() | Pilot Studies Pilot studies are small-scale, exploratory studies focused on answering specific learning questions. These studies require substantial upfront design and implementation investments to refine interventions before scaling to a full impact evaluation. This stage may involve trial-and-error piloting, A/B testing, and qualitative or quantitative data collection to shape the intervention or refine learning questions. |
Applicants will also have access to adaptive management support from the SIEL program. This support focuses on helping teams use data and learning to refine program design and delivery in real time, largely through technical assistance for right-fit MEL activities, short learning cycles, or decision-focused workshops, and can sit alongside other evaluation activities where appropriate.
Please note that we are only able to support evaluations which fit one or more of the above types through SIEL. Such evaluations require the beneficiaries of an intervention to be clearly identifiable, and a comparison or ‘control’ group to be identified, which would not be affected by the intervention.
Impact Evaluation FAQs
When is the best time to evaluate a program?
Evaluations are ideally designed during the program design phase to make sure the evaluation is fully integrated into program planning from the start. However, ongoing or recently launched programs can potentially be evaluated if it remains feasible to establish a valid counterfactual or comparison group. For programs in their final stages (ending within 6 months), opportunities may be limited since comparison groups are typically easier to establish from the outset.
How will the evaluation results be used?
Generating high-quality evidence is only part of the equation—making sure that evidence is effectively used is just as crucial. SIEL will work closely with FCDO teams to help them interpret and apply the evidence in their work, and support the dissemination of findings across FCDO and beyond. This will strengthen knowledge management and organizational learning within FCDO and help deliver more impactful and sustainable programs and policies.
Where can I find examples of impact evaluations to get inspiration for my work?
We recommend the ‘Evidence snapshots’ in SIEL’s learning agendas, which summarize lessons from recent impact evaluations. Other options are IPA's Impact Highlights, J-PAL’s policy publications, and the 3ie Development Evidence Portal. Please also see below for some FCDO projects SIEL is already evaluating.
