Castilleja School Reviews

I am currently a senior at Castilleja, and I would never choose to attend another high school. When I first came, I was a little nervous as I had heard of Casti's reputation as rigorous and competitive. After four years, I have found that the academic rigor has only improved my experience and has never lead to competition between classmates. With sixty girls in one grade, it would seem that competition would be prevalent, especially during the college process. However, the community is one of care, and everyone at the school aims only to celebrate your achievements and encourage you to put forth your best work. Every single one of my classmates will become amazing women when they grow up, and Castilleja has been instrumental in developing our confidence, poise, ability to express ourselves, and compassion for others. Thank you Castilleja! My life is forever changed and I will bring the lessons you have taught me throughout the rest of my life.

This is AMAZING. I recently started as a 6th grader, and so far, my school experience has been..out of this world. I can't describe the wonderfulness of this school in this character limit, but I can tell you that the teachers are so amazing and caring; they really care about your sleep, and don't force you to do homework late in the night. They care about you and your health. Castilleja also has a lot of programs, or C, which are study blocks, or your elective, or grade meetings. During C, you can go to teachers and ask for help, and they help you. There's also something called little C at the end of the day, where the teachers also help you. But, Castilleja has so many fun events and traditions. Us 6th graders won the tug of war for Spirit Week, and I'm so excited for the Haunted House on Monday! I know some people say this is a bad school, but as a 6th grader, trust me, it's the best.
Too good for words. Castilleja is an all-girls, friendly environment. In the classes, they don’t consist of a lot of students, so teachers can get one on one time with their students. The food is absolutely yummy! The tie ceremony is my favorite event! It means the start of a new and amazing year here at Casti. I attended the camps as a CILT (Counselor In Leadership Training), and it is super fun! Castilleja is a tightly knit community, and almost everyone knows the other people in their year! I love Castilleja School, and when I graduate, will miss it forever.
