The Pine Tree ISD was established in 1847, less than two years after Texas became the nation’s 28th state, and James K. Polk was president. Growth was slow but stable, with agriculture being the primary source of income through the turn of the century. The oil boom in 1931 brought thousands of people to East Texas and caused rapid growth for Pine Tree Schools. Since that time, the district’s reputation for quality education has attracted steady enrollment.  Student enrollment is approximately 4,700 for grades PK-12. These students attend a Primary, Elementary, Intermediate, Middle School, Junior High and High School.
