Assessment Tools

Two assessment tools are used to guide the development of a person’s services: the Ohio Developmental Disabilities Profile and the Acuity Assessment Instrument.

Ohio Developmental Disabilities Profile (ODDP)

The Ohio Developmental Disabilities Profile, or ODDP, is an assessment tool that looks at a person's needs and circumstances. When completed, the ODDP sets a funding range for a person that guides the development of their services. People on the Individual Options Waiver and residents of intermediate care facilities are required to have an ODDP completed.

The ODDP is updated regularly and when a person experiences a significant change of condition. Significant change of condition means a change in a person's physical or mental condition or abilities, which may change how the person is cared for. This includes changes like

  • New diagnosis or medication
  • Changes in health status or severity of condition
  • Change in level of independence
  • Change in living arrangement
  • Change in natural supports or voluntary care giving (for people on the Individual Options wavier only)

Acuity Assessment Instrument (AAI)

The Acuity Assessment Instrument (AAI) is the standardized instrument used by Ohio to assesse the relative needs and circumstances of an individual compared to other adults in a non-residential setting when receiving Adult Day Array Services.  The assessment questions measures the amount of staff time required to assist individuals with personal needs and day activities. The score is used to assign the staff intensity ratio at which the services are to be provided and assign costs.            

All individuals who receive or seek to receive any of the HCBS-funded Adult Day Waiver Services need to have this assessment completed.   Individuals who are not receiving HCBS-funded day services but receive day services along with waiver funded individuals also may complete the assessment to ensure that the staff intensity ratios for the waiver individuals are maintained.
