About St. Catherine of Siena
St. Catherine of Siena is a private elementary school in Martinez, CA. St.
Catherine of Siena serves approximately 133 students, and covers grades Kindergarten-8th, and has a 14:1 student-teacher ratio. MySchoolScout does not publish a rating for this profile because there is not enough verified data to rate it fairly. Based on limited data: 0% component coverage.
What Parents Should Know
At 133 students, St. Catherine of Siena is on the smaller side. That usually buys more individual attention and teachers who know every kid by name, with the trade-off of fewer electives and extracurriculars than a larger school can staff. Ask what activities it actually offers.
St. Catherine of Siena is private, so it runs independently of the local district and sets its own curriculum. That freedom cuts both ways depending on what you want for your child. If you're considering it, start with the practical questions: tuition, financial aid, and how admissions work.
