Academics & Activities

BASIS Texas charter schools are public open enrollment, tuition-free schools serving grades K–12 in three schools in the San Antonio area.  BASIS offers students a well-balanced education that allows them to achieve at internationally competitive levels.  Taught by Subject Expert Teachers, the BASIS Curriculum model supports an academic program based on the College Board’s Advanced Placement (AP) standards.  It encourages self-motivation and hard work, helps students master rigorous content, and thoroughly prepares them for college.  BASIS students have been recognized as the state’s top performers on the State of Texas Assessments of Academic Readiness (STAAR), setting the standard for academic achievement in Bexar County.

The BASIS Curriculum for grades K–4 focuses on building a solid academic foundation, while teaching fundamental skills - critical thinking, organization, time management, effective study habits, and behavioral expectations - that prepare students for success.  The BASIS Curriculum is spiraled, building upon concepts taught in previous courses, to facilitate content mastery.  The curriculum for grades 5–7 builds upon the foundations laid in grades K–4, while introducing high-level content standards and an accelerated work pace.  This ensures that students are prepared for honors and AP-level courses when they enter high school. 

The BASIS Curriculum for grades 8–12 is regarded as one of the most academically advanced high school programs in the world, preparing students for success in college and beyond.  The acceleration of the curriculum allows students the option of graduating after 11th grade; however, most students choose to continue their studies in 12th grade in order to complete a Senior Project and Capstone Courses. 

In addition to the core subjects, students also take Music, Art, Drama, and P.E.  Extracurricular activities include clubs such as Academic UIL, Creative Writing, Robotics, Speech and Debate, and Yearbook.  Sports include Basketball, Cross-Country, Flag Football, and Volleyball.
