J-PAL's policy group works with governments, NGOs, international development organizations, foundations and donors to help them determine the most cost-effective ways to achieve certain outcomes in the fields of health, education, governance, environment, agriculture, and microfinance (see Policy Lessons). The group also partners with these organizations to scale-up and massively expand the programs that are found to be effective. If you have more questions about the scale-up process and our current scale-ups in the field, please see our contacts page.

Many programs evaluated by J-PAL and found to be highly effective have been scaled-up by governments and NGOs around the world. To date, these scale-ups have reached at least 40 million people. In addition to this, J-PAL's research has contributed significantly to the policy debate around many programs and policies. More information about some of these scale-ups and policy debates is provided below.
