To help our members find other teachers near them, we have broken the state into different districts. 
Using I40 and I34 as axes, we have divided the state into four quadrants. Districts near the origin (Oklahoma County), will be assigned to District O. The remaining districts will be designated as quadrants are named in the cartesian plane: District I will be the NE quadrant including Muskogee, Stillwater, and Tulsa. District II will be the NW quadrant including Enid, Woodward, and the Panhandle. District III will be SW quadrant including Chickasha, Lawton, and Weatherford. District IV we be the SE quadrant including McAlister, Norman, and Shawnee.
These boundaries are somewhat arbitrary and the intent is not to be prescriptive. There are a variety of reasons why you may you and/or your school may better fit in a different OCTM district. If you feel more comfortable meeting with a different district, please do so.
