Registration at Mount Si High School
Welcome to the Mount Si High School Registration Hub!
Whether you're a current student planning your schedule for next year or a new student joining our Wildcat community, this is your go-to resource for registration information.
Each winter, Mount Si students meet with counselors to prepare for the upcoming school year. During this process, students review graduation requirements, explore course options, and select classes that align with their interests, goals, and post-secondary plans. Counselors provide grade-level presentations and resources to help students and families make informed decisions.
