The British International School of Tenerife educates students aged 11 to 18, divided into Key Stage 3, Key Stage 4, and Key Stage 5 (Sixth Form). The curriculum includes core subjects such as English, math, and science, alongside humanities, arts, and physical education. Schools also emphasize personal development, career guidance, and extracurricular activities.

At the end of Key Stage 3, teachers have advisory conversations with students to help them consider their future studies and choose their General Certificate of Secondary Education (GCSE) exams. GCSE results guide students toward further education paths, such as A-levels, vocational qualifications, or apprenticeships.

The school fully prepares students for their chosen paths, whether that involves studying abroad or taking the Spanish university access exam EBAU (Evaluación del Bachillerato para Acceder a la Universidad) for those wishing to attend Spanish universities.
