Effective, high-quality long-term services and supports (LTSS) systems require a mix of institutional-based options and home and community-based services (HCBS) that enable people with diverse needs to choose where they will live and receive the services needed to thrive.
For decades, Mathematica has been evaluating and informing the design of some of the most cutting-edge care delivery and financing innovations so that people can receive needed services in their home or communities. Our teams combine a deep understanding of LTSS and HCBS policy, program history, current practices, and data with a vision—informed by evidence and community voices—about the opportunities for the future.

Fulfilling the Vision of Accessible HCBS Services
Our experts collaborate with government agencies and community organizations to work on some of the most pressing HCBS policy and delivery issues: service access and quality, direct care workforce shortages, housing capacity, and person centered planning.
