***A word of caution, and to eliminate any confusion, the official standalone DOR T-Ccalc tool can only be found on the DOR website. Extensive testing has produced similar trend results in both programs, but the MAAO Ratio Study Template shouldn't be viewed as a T-Calc replacement. The MAAO Ratio Study Template is intended to provide Minnesota assessors with an additional tool allowing the user to import data and then perform instantaneous sales ratio analyses through customizable stratification, now also including time trend analysis capabilities.***
