Comprehensive school comprises grades 1–9 and is intended for the entire age group (ages 7–17). Basic education is free of charge and provides everyone with the same qualifications for further studies. Basic education offers the pupils an opportunity to build an extensive foundation of general knowledge. The obligations governing the provision of basic education are based on the Basic Education Act, the Basic Education Decree, and the national core curriculum.
Basic education abides by the core conception that pupils are active learners. Learning takes place through interaction with other pupils, teachers, other adults, and various communities and learning environments. The goal is to provide each student with transversal competence, meaning an entity that consists of knowledge, skills, values, attitudes, and will.
There are 29 school units in Salo and, at present, there are approximately 5,000 pupils in basic education.
