Welcome to Thomas MacLaren School

Thomas MacLaren School is a top-performing, tuition-free K-12th grade charter public school. Since our opening in the fall of 2009, MacLaren has racked up impressive awards and test scores while daily undertaking the task of developing young men and women who are fully human and fully awake to the world. We expect each student to master history, mathematics, science, literature, Latin and English, as well as to gain familiarity with at least one other language and fine arts. Our Lower School (K-5) curriculum, full of rigor and wonder, prepares younger students to be able to plumb the depths of the Upper School (6-12) curriculum eagerly and confidently.

Now enrolling for 2024-25 school year


We are proud of the fact that the Class of 2017 posted a Colorado state record-breaking average composite score on the ACT of 29.8! The MacLaren community of learners, anchored by our accomplished faculty, creates an environment that encourages each student to become the agent of his or her education.
