CTE Best Practices Feature

Selkirk High School Waste Water Management Program

Work based learning at it’s finest. The classroom instruction and the WBL component provide a required service to the school district and the communities surrounding it. The students do real life water testing for the school district, the communities of Ione, Metaline, and Metaline Falls, as well as businesses in the area. The water quality of the entire larger community depends on these students work. Many students have gone on to making this a meaningful career.
