Estacada High School marks a proud and deep tradition with its beginnings in 1905  when 9th and 10th grade classes were first taught in the Estacada Grade School, a small 20  by 30 foot building on the west side of Main Street and across from the site of the current  elementary building.

The first Estacada High School graduating class of 1910 consisted of one (1)  graduate.  High school age students continued to be taught in the grade school, moving into  a new grade school that was constructed in 1906 and added on to in 1908 with a duplicate  structure, both on the site of the current Estacada Grade School.

In 1917, high school aged students moved to a new and the first Estacada High  School, which was built behind the 1906-1908 buildings.

Estacada High School students continued to attend school at this site until the fall of  1936 when, at the end of the first semester, students moved into the newly constructed  Estacada High School, the building known today as Estacada Junior High.  During this time,  graduating classes varied in size from 25 to 44 students.

In the fall of 1961, the current high school was opened and accommodated a senior  class that had grown in number to 80.  The entire 9-12 grade enrollment had reached 394.

Since its construction and major remodel in 1981, Estacada High School has undergone many changes.  With enrollment swelling to over 1,000 students in 1980, now there are roughly 800 students enrolled.
