Through studies in language and literature, the DP aims to develop a student's lifelong interest in language and literature, and a love for the elegance and richness of human expression.

Language B courses are intended for students who have had some previous experience of learning the language. They may be studied at either higher level or standard level. Students must choose ONE language.

Studying any one of these subjects provides for the development of a critical appreciation of human experience and behavior and the varieties of physical, economic and social environments that people inhabit. History of the Americas and Government are required, while Global Politics is an IB elective.

Students explore the concepts, theories, models and techniques that underpin each subject area and through these develop their understanding of the scientific method. Traditionally, students at Palo take Biology junior year to satisfy their IB science credit, while some students choose to take Chemistry senior year.

The aims of these courses are to enable students to develop mathematical knowledge, concepts and principles, develop logical, critical and creative thinking, and employ and refine their powers of abstraction and generalization. Analysis and Approaches is recommended for students with strong Algebra II skills and an interest in mathematics and sciences after high school, while Applications and Interpretation is for students who have Geometry skills, are more less interested in pursuing mathematics.

The subjects in the arts allow a high degree of adaptability to different cultural contexts. The emphasis is on creativity in the context of disciplined, practical research into the relevant genres. Visual Arts is a thought-provoking course in which students develop analytical skills in problem-solving and divergent thinking, while working towards technical proficiency and confidence as art-makers.
