Our Mission

To advance the national development, recognition and use of Adult Day Services.

New Definition for Adult Day Services (ADS)

The NADSA Board of Directors has redefined Adult Day Services to help clarify to a wider ranges of audiences what services ADS provides and who it represents in our senior and adult communities. Those audiences include legislators, agencies, payors and caregivers. As the only national organization solely representing Adult Day Services, NADSA wants to ensure all the industry’s constituencies have a clear understanding of the critical role ADS plays in the continuum of long-term care. We hope you will incorporate this new definition into your marketing materials and where appropriate, encourage your state ADS association to adopt this definition for use in its communications.

New definition: Adult Day Services is a system of professionally delivered, integrated, home and community-based, therapeutic, social and health-related services provided to individuals to sustain living within the community.

We are positively impacting the lives of participants, families, communities and our nation.

The organization formed as the result of more than 75 people who attended the National Council on the Aging’s (NCOA) 28th Annual Conference in St. Louis, MO, in 1978 who advanced a resolution for NCOA to serve as a focal point for the adult day care field.

A National Task Force on Adult Day Care was named and work began. The National Institute on Adult Daycare (NIAD) was formally organized as an NCOA unit in 1979. NIAD changed its name to the National Adult Day Services Association (NADSA) in 1995 to better reflect the trends of the rapidly growing industry to focus on day services. The name was also more inclusive of centers providing day care, day health and/or respite.
