The Assessment Interval represents the frequency at which an assessment may be run, for example 30 days. It is used to calculate the reassessment due date of an assessment. For example, if an assessment is run on the 01/01/2011 and the Assessment Interval has been set to 30, the reassessment due date is 31/01/2011. The Reassessment Warning Days works in conjunction with the Assessment Interval and is used to alert the case worker who executed the last assessment that a reassessment is due. For example, the Reassessment Warning Days may be set to 5 days. In this case, a task can be created 5 days before the reassessment due date and assigned to the case worker who last ran the assessment.
