Secundaria is a stage of education in many countries, typically following Primaria and preceding Preparatoria or Bachillerato. It usually serves students aged 12 to 15 years and focuses on a broad curriculum that includes subjects like mathematics, science, language, and social studies. The goal is to provide foundational knowledge and skills necessary for further education or vocational training. In some regions, Secundaria is divided into two or three grades, and students often take standardized tests to assess their progress. This educational level aims to prepare students for the challenges of higher education and to develop critical thinking and problem-solving abilities.
