In 1965 the Court of Appeals of Kentucky ruled that all property should be assessed at 100 percent of fair market value. In compliance with the court decision, the county assessors began reassessing properties in January 1966. A great controversy arose over the new assessment procedures and problems. This study evaluates the results of the 1966 reassessments and develops a way by which the assessment procedures might be improved. The study first determines the effect of the 100 percent assessment in one area of Kentucky, giving particular emphasis to how well it improves the degree of equity among property assessments. It then describes the development and testing of a method that improves the 100 percent assessment procedures through the use of a regression model involving computer data processing. (Author/DN)
