School Year 21-22: We Are More Powerful Together

Students and families, we are so excited to be back together in person for the 2021-22 school year. Here are links to important start of year information:

2021-22 Weekly Schedule & Calendar. Note: We have adjusted our Wednesday early dismissal to 12:45, with a grab and go lunch, for the 2021-22 school year. This is necessary because of space limitations and need for social distancing that impacted our Wednesday lunch waves. We will continue to provide supervision on an as-needed basis to students on Wednesdays until 1:30 through September.

Our Results

In each of the last 5 years, between 97% and 100% of our graduates were accepted to college. Our 4-year graduation rates significantly exceeded the state average in 4 of the 5 last school years. Recent Common Ground 9th and 10th graders have made greater gains in reading, writing, and math than 90 or more percent of their peers across the country, according to results of the NWEA MAP. Common Ground was the state’s first U.S. Department of Education Green Ribbon School and a recipient of many awards and grants in recognition of our work.

Our Approach to Learning

Common Ground’s curriculum combines rigorous high academic standards for all, responsive relationships with adults and peers who really care, relevant, real-world learning that’s rooted in the community and environment, and real roles and rights for students. Imagine studying …

  1. Math while you … decide what should be planted on Common Ground’s farm to maximize production, nutrition, taste, and cultural relevance.
  2. Science while you … turn what you are learning about climate change into beautiful paintings, spoken word, and graffiti art
  3. English while you … work with professional actors to write and perform plays about social justice issues that matter to you.
