Developmentally Disabled Services Day Training Agency: how many are there, and how many are in private practice?

National totals

What this specialty covers

These agencies are authorized to provide day habilitation services to developmentally disabled individuals who live in their homes. The function of day habilitation is to assist an individual to acquire and maintain those life skills that enable the individual to cope more effectively with the demands of independent living. Also to raise the level of the individual's physical, mental, social, and vocational functioning.

Reading the sole-proprietor share

For this specialty, 1,455 records, or 12.4%, are flagged as sole proprietors in NPPES. This is a self-reported NPPES field and an imperfect proxy for private practice because it does not by itself establish an agency's ownership, staffing, service setting, or independent operation.

By state

New NPI registrations by year

Data notes

• The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
• A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
• NPI records are identifiers, not a guaranteed count of distinct operating agencies or current service activity.
• The primary taxonomy is reported in NPPES and may not capture every service an agency provides.
• Providers are counted once, by their primary taxonomy code only.
