The Pine Tree Independent School District 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.

(sung to the tune of "You're a Grand Old Flag")

Pirates fight, fight, fight
Give em' all of your might
Pirates fight for the old blue and gold.
The Pirates are the best by far,
Daring, Courageous, and Bold.
Pirates go, go, go
Till you conquer your foe
Pirates fight and they never die
So now we fight for victory,
For that good old Pine Tree High. 

Pirates Fight for old Pine Tree High
For your Alma Mater dear
Pirates fight for Old Pine Tree High, 
For Victory is near, 
To Pine Tree we’ll be loyal 
‘Til the sun drops from the sky 
Remembering until the end, 
Pirates fight, never die.
