The mission of the Sentinel Tech Alternative is to provide alternative educational opportunities necessary for our students to acquire knowledge and skills, to develop the values of responsibility and respect for self and others, leading to productive citizenship and lifelong learning. We service students in the Mattawa Area in grade 9-12 who are behind in credits, want a different type of learning experience or have circumstances that make distance learning a better fit for them. We offer core subjects as well as foreign languages, fine arts, computer science, career planning, CTE and other electives. All credits earned at ST meet Washington State requirements and are accepted by colleges and universities.
