In Spanish-speaking countries, 'bachillerato' is not slang but a formal term referring to the stage of education equivalent to high school or senior high school. It is a period of two or three years of schooling before university.
Examples
- Spanish: Después de terminar el bachillerato, Ana decidió tomar un año sabático antes de ir a la universidad.
- English: After finishing her bachillerato, Ana decided to take a gap year before going to university.
