As a parent, I researched for the best possible Jr/Sr High School for my kids and I unequivocally found it in D'Evelyn. While their test scores are unbelievable (top ACT/SAT for 18 years running in CO), what is more impressive is their curriculum. They believe all students can succeed in their Liberal Arts curriculum and the staff gives the students what they need to do so (students must, of course, be willing to do the work). In today's educational world where our students are guinea pigs for every new fad, D'Evelyn has stayed true to its philosophy for 25 years. They teach the students knowledge and allow the students to come to their own conclusions, avoiding the normal political bias of today. The staff is carefully selected for those who truly believe in what they are doing at the school and they are required to have expertise in their subject (i.e. Chemistry teachers actually have Chemistry degrees). Because of these policies, they have the best staff I have seen and the students are reaping the benefits. Additionally, because all staff are committed to the philosophy of the school, all are rowing in the same direction, allowing the school to continue to improve in any way that is necessary. There is not a school in the area that I would have rather sent my kids to. Enrollment is based on computerized lottery (no testing) and the best chance to get in is in their first year of middle school (though they do enroll through 9th grad when spots become available). The Jr - Sr High platform also makes it so kids do not have to go through an additional transition during their hardest years. The Sr. High students act as mentors for the middle schoolers, which is also a large benefit. Hopefully, you will get the golden ticket like our family did!
