I've worked at a number of other schools and have had my children in several other schools as well. As a current employee, I can say this is by far the best school I've work for and better than any school my children attended. The staff go above and beyond to help each student. They offer terrific after school programs including clubs and athletics, their outdoor education is program is easily one of the best in the state, and the school has won state and national awards for outstanding communication. Just Google "Hood Canal School Awards" as see the long list of staff and school awards that shows up. You really can't go wrong with Hood Canal!
