The Idaho Council of Teachers of Mathematics makes every effort to meet Idaho's educators where they are. To reach this end, ICTM's organizational endeavors are divided into seven educational regions as outlined by the Idaho State Board of Education. These regions host local activities that give math teachers an opportunity to learn new practices and connect even deeper with their local peers, enriching an environment of education growth across the state. Each region is represented by two elected chairs on the Board to ensure that all members' voices are heard!

Please note that, given its populace, ICTM further divides Region 3 into two subregions. Region 3A is constituted of the Boise and West Ada School Districts with the rest of the districts in the region classified as Region 3B.
