Agencies normally require clients to notify them in case of any change of circumstance. This is relevant for assessments because the change may have an impact on the determination results. For example, a client may be receiving income support because his earnings were lower than the limit defined by the government. His salary and wages are then increased as a result of a promotion. The client has to inform the agency of this change of circumstance, so that the income support given to him can be re-evaluated. The Support CoC indicator is used to support scenarios such as the one above, where a determination must be repeatable over time as client circumstances change. For each new determination, new evidence can be collected and new decisions can be made.
Not all determination types require a determination to be repeatable over time. In some cases, the agency may not wish to change the determination decision for an assessment, but prefer to create a new assessment and re-run the determination. For such determinations, the Support CoC indicator must not be set.
