ID S1216

Amends Section 63-208 of Idaho Code to change property assessment standards from requiring a median ratio of assessed value to market value to requiring assessments within 90% to 110% of market value

Requires each category of property tested to have assessment levels provably within 5 percentage points of each other category to ensure uniformity across property types

Mandates corrective actions if assessment ratios fall outside the 90-110% range, using statistical methods such as confidence intervals to determine compliance

Removes reference to "median ratio" language from the original House Bill 354, replacing it with direct market value comparison standards
