Welcome to LASIS

At La Sierra International School, education is more than academics — it is belonging, character, and global vision. Since opening our doors on August 15, 2012, we have built a close-knit community where every child is known, supported, and inspired to grow with confidence and purpose. With 626 students from K2 to Grade 12 and a diverse team of national and international educators, LASIS combines bilingual excellence with strong character formation in a campus surrounded by the beauty of the Sierra Nevada. As the only ACCAS member school in Valledupar and aligned with Cognia accreditation standards, we offer our students access to a prestigious international network, high academic expectations, and opportunities to connect, compete, and collaborate with leading schools across Colombia. At LASIS, we do not simply educate students — we prepare leaders with heart and a global mindset.
