How to make the most of the Application Package for Developmental Services and Supports
In this video, you will learn more about the three tools the DSO prepares that inform service planning and linking to resources. The video includes a review of the Assessor Summary Report (ASR), followed by a review of the Application for Developmental Services and Supports (ADSS) and the Support Intensity Scale – Adult version, 2nd Edition (SIS-A, 2nd Edition). These tools provide a deeper understanding of a person’s strengths, goals and support needs, which informs how they can be well supported by your organization or by a support worker.
