Organization description & mission
18F is an internal technology and design consultancy as part of the Technology Transformation Service (TTS) in the General Services Administration (GSA) in the U.S. Federal Government. Their teams work with federal agencies to build and buy technology, and can also work with states and local agencies on initiatives receiving federal funding. They seek to build digital services that are trustworthy, designed with the people who use them, deliver good value, and are shipped efficiently and when possible, in the open.
Approach to eligibility
Starting in 2017 through 2020, a team at 18F received multiple rounds of funding through 10x, the GSA’s technology innovation fund, to explore and prototype how the federal government could communicate benefit eligibility rules as computer code for integration into state systems. Under their Eligibility APIs Initiative, the team built a prototype API and calculator for the federal rules for SNAP. Initially, the team wanted to build a backend eligibility rules engine, but determined that a pre-screener was a lower risk way to explore how a rules as code approach could help model complex SNAP eligibility rules. TTS is a potential long term home for a central shared service for eligibility rules across all safety net programs.
Rules Structure & Technology
Deploying the project also involved essential non-technical work, including listening to stakeholders to understand the need for a SNAP pre-screener, and promoting the work to other open source networks to see if it created value for other groups. The Virginia Poverty Law Center deployed the code to their own website as part of a Virginia-specific SNAP calculator; civic tech volunteers later adapted the code from 18F to create SNAPScreener.com, which extends the data model to all U.S. states and territories.
How They Write Rules
The technologists at 18F led the prototype rules data format and code, which was then validated with the U.S. Department of Agriculture’s Food and Nutrition Service Agency which oversees SNAP, and with SNAP policy experts at Virginia Poverty Law Center.
