Finland has a population of over 5 million people concentrated in the southern region. One of the keys to Finland's success is its high-quality education system, which provides public investment in education and training. Finland's education system includes 9 years of compulsory primary education, after which students can choose between general and vocational secondary programs. It also has a bilingual focus, with most students learning two additional languages starting in third grade, and some schools offering content instruction in other languages through immersion or CLIL programs to further improve students' language skills. Recent international assessments show Finland remaining among the top countries in reading and science, though its math scores have declined slightly.
