Welcome to Jefferson Jr/Sr High School!
Our vision for Jefferson Jr./Sr. High School is to create a community that prioritizes inclusivity and academic equity to build pathways for every student.
Summer School 2026
Need help registering for Summer School? We will be hosting an event on Friday, May 15th to answer your questions and guide you through the process.
Stop by in the morning from 8:30 to 10:30, or in the afternoon from 1:00-3:00.
Cell Phone Policy Reminder
ALL students must place cell phones in the provided pocket holder or box upon entering each classroom. Students may keep phones in backpacks, but may not be out during class. This helps everyone stay focused and engaged.
Repeated violations of this policy will lead to the cell phone being confiscated by administration and/or security.
8th Grade Continuation Ceremony
On May 27th, will be celebrating our 8th graders as they become high school students. Please join us in the gym at 6 PM; snacks and refreshments will be provided.
Free Summer Meals For Kids
We are excited to offer Summer Food Service for Jeffco students and families! Student meals are free; Adult meals can be purchased for $5.75.
