Supports Intensity Scale

Supports Intensity Scale (SIS®) 


  • Adults (age 16+) with an intellectual / developmental disability (I/DD). 
  • The assessor, the person served and at least 2 support people who the individual chooses to answer questions.


  • When you begin services and every 3 years.
  • You will receive a letter, then a call from a certified assessor to schedule a time and place best for the individual and supports to talk for about 1.5 - 2.5 hours. 


  • The assessor will ask questions about many common adult activities / behaviors / medical conditions and explore supports needed to have success just as anyone else the individual's age.


  • Lapeer CMH uses the Supports Intensity Scale (SIS ®) as a standardized assessment tool.
  • Finding out a lot about individuals, what they like or don't like and how they are best supported helps us to serve them better,
  • Better informed person-centered planning.
