Our daughter is a senior at The Marin School (TMS) and we couldn`t be happier. We feel so lucky that we found TMS and decided that the commute from San Francisco would be worth it. It has been, and more. We were looking for a school that could provide individual attention and differentiated learning for our daughter while also challenging her academically. We have had first-hand experience with schools that say that they provide this, but in fact don`t. It can really only be done with dedicated teachers and a small student:teacher ratio. We knew TMS had a small student:teacher ratio when we applied, but found out how talented , dedicated and caring the teachers are at TMS once our daughter started in 9th grade. She`s now a senior and has grown tremendously and is well prepared for college. We are honestly blown away by the ability of TMS to provide excellent, supported, standard and honors courses for core subjects. We`re impressed by the school's ability to meet the needs of all students not just because of its size, but because it`s so rare. We were initially concerned about the social life at TMS because it`s small, but through clubs, lunch, where all grades are combined, and the culture at TMS, our daughter has always had many friends, with friends in different grades. We are highly satisfied.

The Marin School has been a terrific school for our daughter over the past two years. They have provided the right level of individualized instruction and focus for her. She has participated in student government and other leadership opportunities, which she has really enjoyed. The school has created a community in which has been easy for our daughter to make friends. All in all, we`ve been very happy with the school!

TMS is a fabulous school for our child. The small class size and great teachers & staff make all the difference. They really care about each individual student. Being so small, less than 100 students in grades 9-12, enables TMS to give each student everything they need, whether it be more challenge, tutoring or emotional support. We are extremely happy with this school.
