What Parents Should Know

With a student-teacher ratio of 8:1, Sierra School of Alhambra offers a notably low ratio compared to the national average. This typically means smaller class sizes and more opportunities for one-on-one interaction between students and teachers.

As a private school, Sierra School of Alhambra operates independently from the local public school district.
