The educational system in Lithuania has several stages. Pre-school education is mandatory for children aged 6 and younger and focuses on social and cognitive development. Primary education lasts 4 years and emphasizes literacy, social, and cognitive skills. Basic education then lasts 6 years and provides students with general knowledge and skills. At upper secondary level, students can choose a gymnasium or vocational program. Gymnasiums last 2 years and prepare students for university. Vocational programs offer qualifications upon completion. Assessment standards become more standardized at higher levels, culminating in state exams for university entrance.
