SIL/SDA Assessments

What Are SIL and SDA?

Supported Independent Living (SIL) provides participants with assistance to complete daily tasks in their home, enabling them to live as independently as possible. Specialist Disability Accommodation (SDA) is housing designed or modified for participants with extreme functional impairment or very high support needs. Both SIL and SDA require detailed occupational therapy assessments to establish eligibility and determine the appropriate level of support.

SIL Assessments

Our occupational therapists conduct functional assessments to determine a participant's capacity for independent living and the level of support required. SIL assessments evaluate the participant's abilities across all areas of daily living and identify the supports needed to live safely in the community.

• Assessment of personal care, meal preparation, and household management capacity
• Evaluation of overnight support and supervision requirements
• Risk assessment for safety, health management, and community participation
• Detailed support needs analysis with recommended staffing ratios
• Reports suitable for NDIS plan reviews and SIL quoting

SDA Assessments

SDA assessments require a thorough evaluation of the participant's functional impairment and housing needs. Our occupational therapists prepare detailed reports that address the NDIS SDA eligibility criteria, including evidence of extreme functional impairment or very high support needs.

• Functional impairment assessment against NDIS SDA criteria
• Identification of appropriate SDA design category (improved liveability, fully accessible, robust, or high physical support)
• Assessment of current living environment and its suitability
• Evidence-based reporting to support SDA funding requests

Participant Capacity and Support Needs

Understanding a participant's capacity is central to both SIL and SDA assessments. Our occupational therapists use standardised assessment tools and clinical reasoning to build a clear picture of what the participant can do independently, where they need assistance, and how the right living environment and supports can promote greater independence and wellbeing.
