6 (COCSD) is a school district in Arizona, United States, headquartered in Cottonwood.

The Cottonwood School opened in 1909 serving students from ages 6–17 who had to carry water from a well 1.4 miles away.

From 1917 to 1923 the Bungalow School educated students whose parents worked for the United Verde Extension's mine and smelter in the company town of Clemenceau.

In 1923, a modern public school was built by James Douglas, owner of the United Verde Extension, for $100,000, which still proudly stands today!

That same year Yavapai County students from Sedona joined the Cottonwood-Oak Creek School District.
