Divide Independent School District

Divide Independent School District is a public school district based in the community of Mountain Home in western Kerr County, Texas, United States.

In terms of students served, Divide ISD is the smallest district in Texas; the 2015 "graduation/promotion ceremony" featured a mere 11 students and the district had as few as eight students at the beginning of the 2014–2015 school year. Divide ISD serves much of western Kerr County. Divide ISD is one of the few remaining schools called "one room schoolhouses" in the United States. Technically it is not a one-room schoolhouse according to a Texas Monthly article by Katy Vine, as the original school building – still in use – does not hold the pre-Kindergarten classes. In the original building there are two classrooms since the district divided the original single room into two.

Divide Independent School District consists of one school: Divide Elementary School, serving grades pre-Kindergarten through six. Students attend middle and high school in the neighboring Ingram Independent School District.

In 2007 it was rated "exemplary" by the Texas Education Agency. Katherine Leal Unmuth of The Dallas Morning News stated that year that, because Divide ISD had such a small student body, it could more easily get an exemplary rating under TEA rules at the time compared to larger districts; due to differing demographics, Divide ISD could gain exemplary ratings by succeeding in three of 36 different tasks.
