The Oregon Trail School District (OTSD, OT46) is a public school district in Sandy, Oregon. It covers 424 square miles (or 1,100kmò) of Clackamas County, Oregon, extending across Boring and Sandy to the surrounding areas of Mount Hood and the county's border.
In 1997, OTSD was formed by the merging of six school districts; Bull Run, Boring, Cottrell, Sandy, Sandy Union, and Welches. This decision was most likely made due to Oregon Legislature ruling that all school districts needed to have a separate high school. The name came from the Oregon Trail, where the ending of it is in the area.
The district was named the eleventh best school district in Oregon by SchoolDigger in the 2023-24 school year.
The board of directors consists of seven members, two elected at-large, and five elected by zone.
