The Department performs standard sales ratio studies to determine both the level of assessment and the coefficient of dispersion. To determine the jurisdiction’s current level of assessment, the department uses the most recent three-year adjusted median as determined by the assessment/sales ratio study. For example, for the 2005 bonus, the department will use the 2002, 2003, and 2004 levels of assessment. Since this is a performance bonus and since sales ratio studies compare the prior year equalized assessed value to the current sale price, the current year action by the assessor needs to be taken into consideration. This gives the assessor the opportunity to take corrective action if the assessments are not at the proper level. Therefore, adjustments to the study data may be made on the basis of changes reported by the assessor in Section 3, Column 2 of Form PTAX-205. The department uses the most recent single year assessment/sales ratio data to determine if the coefficient of dispersion qualifications are met. For example, for the 2005 bonus award, the department will use the 2004 single-year sales ratio study.
