school recommends

Exemplar of education UK.
Teaching is focused on seven key subject areas: Catechism, English, Mathematics, Music, Science, Latin, and French. The Saint Benedict Academy is an Education Centre, not a school, providing an integrated program of lessons in key subject areas, while the rest of the teaching is given at home. I would add Greek, German, art, and history. The center prepares students for the General Certificate of Secondary Education Advanced Level (GCE A Level) leading students to direct university entry. To obtain qualification, students undertake a 2-year course normally starting at age 16.

My California recommendations
ART - Academy of Art San Francisco
STEM – Caltech Pasadena, Stanford Palo Alto
LIBERAL ARTS – Thomas Aquinas Santa Paula
MUSIC – San Francisco Conservatory of Music

“At Thomas Aquinas College, there are no majors or minors, no textbooks or classroom lectures. Students carefully read straight from the greatest works of Western civilization, the texts that have shaped how we view the world today: Aristotle, Dante, St. Thomas Aquinas, Isaac Newton, John Locke, Jane Austen, Albert Einstein, among many others.
 
“Rather than the ordinary approach of isolating technical knowledge into specialties, Thomas Aquinas College unifies the principal arts and sciences — philosophy, theology, mathematics, the natural sciences, history, literature, and music — into a single, integrated curriculum, culminating in a Bachelor of Arts degree in liberal arts.”
​
Note: other schools are safe for STEM, but Aquinas is the only safe school for Liberal Arts, free of indoctrination and hatred.
