The Supports Intensity Scale-Adult Version ("SIS-A") has been widely adopted throughout North America and the world since its publication a little over a decade ago. Many organizations and jurisdictions operate under regulations that require an annual assessment of people who receive services and supports that are financed through public funds. The time and energy devoted to an annual "SIS-A" reassessment has become a concern in cases where the resulting information is largely redundant with information from a prior assessment. This article presents findings from an investigation of two approaches to creating a protocol to assist "SIS-A" users in distinguishing situations where there is a high likelihood that support needs have not changed in meaningful ways from situations where there is a reasonable possibility that support needs have changed. The "SIS-A" Annual Review Protocol was created based on these analyses as well as consideration of conceptual issues associated with support needs assessment. Ways in which this protocol might be used, as well as data that need to be collected to evaluate its usefulness, are discussed.
