Pandemic Response

Due to the unprecedented nature of the pandemic, we give charities such as this one the opportunity to share the story of COVID's impact on them. Charities may submit their own pandemic responses through their nonprofit portal.

Evidence Action Inc. reported being impacted by COVID-19 in the following ways:
  • Program Delivery

  • Revenue

  • Staffing

  • Administrative Capacity

  • Balance Sheet

How COVID-19 impacted the organization's operations financially:

The organization’s financials were impacted in multiple ways, though we were able to adapt under these difficult circumstances. One of the main adverse impacts of the COVID-19 pandemic was to our Deworm the World Initiative, which helps governments deworm children using a school-based delivery model. With schools closed for most of the year due to lockdowns, program activities and expenditures dropped by approximately 35%. This led directly to a lower recovery of indirect costs, which are critical to paying for the operations of the organization. Despite this, we managed to make up this gap from reserves and retained our full staff complement throughout the year. Throughout the pandemic, Evidence Action’s donors remain supportive. In mid-2020 we were able to raise urgent funding that provided critical supplies to help prevent the spread of COVID in communities where Dispensers for Safe Water operates, and giving from individuals increased in 2020 compared to 2019.

How COVID-19 impacted the organization's delivery of programs:

Our Dispensers for Safe Water program adapted to ensure continued access to safe water by distributing enough chlorine for several months. We also carried out emergency distributions of soap, disinfectant, and hygiene education materials by our community-elected volunteers to help prevent COVID. Our Deworm the World Initiative also adapted significantly. In Pakistan, we worked with several states to support a new round of deworming treatments. In Kenya, following school closures, we helped the government restart school-based deworming in early 2021 and successfully prototyped a new method to validate deworming coverage with social distancing. In Nigeria, we are working with multiple states to restart school-based deworming treatments. In India, we helped shift school-based deworming programs to community-based delivery to reach children at home, along with providing iron and folic acid supplementation. We also supported states with data analysis, communications, and contact tracing.

How this organization adapted to changing conditions caused by COVID-19:

In addition to adapting our programs to accommodate lockdowns and school closures, we undertook a tremendous amount of risk analysis and planning to determine how best to keep our teams safe while ensuring continued program impact, constituting a global rapid response team that met regularly to discuss emerging program and organizational risks, and develop and monitor related action plans. We increased flexibility in leave policies for all staff globally, providing for additional COVID-related leave. As a global organization, many of our staff are accustomed to working virtually. We therefore shifted quickly into remote work across many of the countries where we operate, leveraging online and cloud-based systems while avoiding major disruptions to daily tasks. We also suspended international and domestic travel for a significant portion of 2020, relying on these same systems to continue our work and local teams’ ability to continue work in the field when sufficiently safe to do so.

Innovations the organization intends to continue permanently after the pandemic:

Most of the changes we conducted during the pandemic, in particular those related to program delivery, have been in response to adverse situations and will not be permanent, as previous modes of working have been optimized through evidence-based iterative processes of improvement over many years. The innovations or changes that have seen positive benefits will require more data to analyze whether we will continue using them. This type of analysis is currently taking place in Kenya by our MLE team to validate the promising results from a pilot we conducted that replaced in-person interviews for coverage validation of our deworming data with remote coverage validation using phone calls. In the preliminary results, the pilot, which was implemented to protect our frontline workers and beneficiaries' communities, showed similar levels of data quality and, if proven to be as robust as the traditional method, could be a more cost-effective way of conducting coverage validation in the future.

Time Period of Data

Learn how we assess the impact of nonprofits

Outcomes and Cost

Outcomes: Changes in the lives of those served by a nonprofit. They can be caused by the nonprofit.

Costs: The money spent by a nonprofit and its partners and beneficiaries.

Impact: Outcome caused by a nonprofit relative to its cost.

Cost-effectiveness: A judgment as to whether the cost was a good use of resources to cause the outcome.

Outcome Metric

A year of clean water provided to a person.

Outcome Data Source

Ratings are based on data the nonprofit itself collects on its work. We use the most recent year with sufficient data. Typically, this data allows us to calculate direct changes in participants' lives, such as increased income.

Output data collected during the program. The nonprofit publicly reports data on how many purifiers it distributes and how many people a purifier serves, which we use to calculate how many person-years of clean water a nonprofit provides.

Method for Attributing Outcomes

We don't know if the observed changes were caused by the nonprofit's program or something else happening at the same time (e.g., a participant got a raise). To determine causation, we take the outcomes we observe and subtract an estimate of the outcomes that would have happened even without the program (i.e., counterfactual outcomes).

We estimate the number of person-years of clean water the nonprofit provides by comparing the person-years actually achieved to the person-years that would have been achieved even in the absence of the nonprofit (the "counterfactual"). Some beneficiaries might have accessed clean water from other providers or on their own; these counterfactual successes must be netted out of the successes we observe. Otherwise, we would be attributing a change in a person's life (gaining clean water) to the nonprofit when it would have happened anyway. Few nonprofits estimate the counterfactual themselves, so we construct our own counterfactual estimate based on research and publicly available data. We research the average rate with which clean water access is increasing year over year in that location, and assume that, if the nonprofit had not intervened, that trend would have continued.

Cost Data Source

After estimating the program's outcomes, we need to determine how much it cost to achieve those outcomes. All monetary costs are counted, whether they are borne by a nonprofit service deliverer or by the nonprofit’s public and private partners.

Program cost data reported by the nonprofit. Partner and beneficiary costs reported by the nonprofit or estimated by Charity Navigator.

Cost Calculation

$4,285,899 program costs + $0 partner costs + $0 beneficiary costs = $4,285,899 total costs

Impact and Determination

We calculate impact, defined as the change in outcomes attributable to a program divided by the cost to achieve those outcomes.

Impact Calculation

$4,285,899 total costs / 9,144,994 person-years of clean water = roughly $0.50 provides clean water to a person for a year.

Benchmark for Rating

Impact & Results scores of water purification programs are based on the cost to provide clean water relative to the market cost that a person incurs to buy water in that country. Programs receive an Impact & Results score of 100 if they provide water for less than 75% of the estimated market costs, and a score of 75 if they do so for less than 125%. If a nonprofit reports impact but doesn't meet the benchmark for cost-effectiveness, it earns a score of 50.


Highly cost-effective

Analysis Details

Analysis conducted in 2019 by ImpactMatters. An analyst searched the Form 990s, annual reports, audited financials and the website of the nonprofit to calculate impact and rate cost-effectiveness. A second analyst conducted quality control.

Evidence Action invests in leadership development opportunities across levels for its staff. Our US-based staff has access to leadership development courses through an external organization called The Management Center, based in Washington DC, and our HR team is researching other local training programs for our employees in the other countries we operate. All US-based staff are encouraged to take a training course called “Working for Change” which helps people define and “own” their workflows, and those in a managerial position receive an additional course in project management and effective leadership. We hold regular meetings for global and regional management teams that discuss key elements of leadership and contribute to skill building.

Mobilizing for Mission

The nonprofit provides evidence of leadership through focusing externally and mobilizing resources for the mission.

This organization mobilizes for mission in the following ways:
  • Strategic Partnerships

  • Networks of Collective Impact Efforts

  • Thought Leadership

  • Raising Awareness

  • Community Building

What are this organization’s external mobilizaton efforts?

Evidence Action’s work is inherently tied to the work of our partners. All of our programs operate in close coordination with national and sub-national governments, either through our role as a technical assistance partner or through direct implementation. In addition, our programs are built on strong community networks, including teachers who are trained to deliver deworming medication to children at school, and community volunteers who educate communities about the importance of using dispensers to ensure their water is safe to drink. We also regularly engage with research institutions to assess the performance and impact of our programs; work closely with other NGOs to advocate for policy interventions; and collaborate with private institutions to increase the impact of our programs. We are committed to sharing and helping others replicate how we translate research and evidence into at-scale impact, by participating in communities of practice, strategic events, and conferences.

Story of Adaptability

The nonprofit has an opportunity to tell the story of how the organization adapted to tremendous external changes in the last year.

During the pandemic, Evidence Action was able to continue program operations and provide additional support to the communities we serve. By leveraging existing resources and relationships, we adapted our program delivery to enable the continuation of high-impact and cost-effective interventions in geographies where such programming is essential for maintaining the health of populations. Our Dispensers for Safe Water program adapted its model to ensure communities had continued access to safe water. In mid-2020, we undertook an emergency response to distribute soap, disinfectant, and hygiene education materials to +67,000 communities with the help of our community-elected volunteers we call promoters. Following initial COVID disruptions, by Oct. 2020 we repaired or replaced +5,000 dispensers and delivered approximately 500,000 liters of chlorine, keeping 27,000 dispensers stocked to provide safe water through Jan. 2021 before returning to normal operations. Our Deworm the World Initiative has worked to support governments in adapting school-based deworming programs in the midst of school closures. In Pakistan, we are working with provincial governments to conduct a new round of deworming treatments beginning July 2021. Following school closures in Kenya, we helped the government restart school-based deworming in early 2021, and successfully prototyped a new method to validate deworming coverage while maintaining social distancing. In Nigeria, we helped the government safely launch a new deworming program in Lagos in May 2021 and are working in other states to restart school-based treatment. In India, we helped the government shift school-based deworming and iron and folic acid supplementation programs to community-based delivery, providing children with continued access to treatment at home. We also used our analytics capabilities to support state governments' COVID-19 response with rapid data analysis, communications materials, and patient and contact tracing.
