Procedures for Boise
			 School District Ratio Studies
. The ratio study conducted by the Tax
			 Commission to comply with the requirements of Section
			 63-315, Idaho Code, will be
			 conducted in accordance with the "Standard on Ratio Studies" referenced in Rule
			 003 of these rules. The following
			 specific procedures will be used. (3-31-22)
a. Information on property sales, which meet
			 the requirements of arm's length and market value sales, will be obtained and
			 assembled into samples representing various primary categories, described in
			 Subsections 130.02 through
			 130.06 of these rules, and
			 secondary categories, described in Rules
			 510,
			 511, and
			 512 of these rules, within
			 designations defined in Subsection
			 315.02 of this rule in the Boise
			 School District. Except when sales or appraisals must be added or deleted to
			 improve representativeness, sales used will be those occurring within the Boise
			 School District between October 1 of the year preceding the year for which
			 adjusted market value is to be computed and September 30 of the year for which
			 adjusted market value is to be computed. Each sale price is to be adjusted for
			 time and compared to market value for assessment purposes for the year for
			 which adjusted market value is to be computed, to compute ratios to be
			 analyzed. The Tax Commission may use sales from extended time periods and may
			 add appraisals when data is lacking. The Tax Commission may delete sales when
			 necessary to improve representativeness. (3-31-22)
b. A ratio will be determined for each sale
			 by dividing the market value for assessment purposes of the property by the
			 adjusted sale price or appraised value. (3-31-22)
c. A statistical analysis is to be conducted
			 for the sales and any appraisals in each property designation described in
			 Subsection 315.02 of this rule in the Boise
			 School District and appropriate measures of central tendency, uniformity,
			 reliability, and normality computed. (3-31-22)
d. With the exception of any property
			 designations with extended time frames or added appraisals, if fewer than five
			 (5) sales and appraisals are available, no adjustment to the taxable value of
			 the designation will be made. (3-31-22)
e. If there are five (5) or more sales and
			 appraisals and it is determined with reasonable statistical certainty that the
			 property designation is not already at market value for assessment purposes, an
			 adjusted market value will be computed for the Boise School District by
			 dividing the taxable value for the year for which adjusted market value is to
			 be determined by the appropriate ratio derived from the ratio study. The
			 appropriate ratio to be used will be the weighted mean ratio calculated from
			 the sample for each designation, unless it can be clearly demonstrated that
			 this statistic has been distorted by non-representative ratios. In this case
			 the median may be substituted: (3-31-22)
f. Within the Boise School District, adjusted
			 market value or taxable value for each primary and each applicable secondary
			 category of real, personal and operating property will be summed to produce the
			 total adjusted market value for the Boise School District. The Boise School
			 District taxable value will then be divided by this adjusted market value to
			 produce the overall ratio of assessment in the Boise School District. Statewide
			 totals are to be calculated by compiling county totals. (3-31-22)
g. Urban renewal increment values will not be
			 included in the taxable value or the adjusted market value for the Boise School
			 District. Upon receipt of an urban renewal agency's resolution recommending the
			 adoption of an ordinance for termination of a revenue allocation area by
			 December 31 of a given year, the increment value in the immediate prior year
			 will be included in the taxable value and the adjusted market value for the
			 Boise School District. If the resolution is received prior to the first Monday
			 in April, the actual value for the immediate prior year will be adjusted by
			 adding the increment value. If any ratio study-based adjustments are warranted,
			 as provided in this rule, they applies to the actual value including the
			 increment value. If the resolution is received on or after the first Monday in
			 April, but by September 1, a corrected certification of actual and adjusted
			 values will be provided as soon as practical. (3-31-22)
h. "Reasonable statistical certainty," that
			 the property designation in question is not at market value for assessment
			 purposes, is required. Such certainty is tested using ninety percent (90%)
			 confidence intervals about the weighted mean or median ratios. If the
			 appropriate confidence interval includes ninety-five percent (95%) or one
			 hundred five percent (105%), there is not "reasonable statistical certainty"
			 that the property designation is not at market value for assessment purposes.
			 (3-31-22)
i. Primary and secondary
			 categories subject to adjustment following the procedure outlined in this rule
			 and ratio study designations from which measures of central tendency used for
			 adjustments will be derived are:
