What Chungdahm Learning does
Chungdahm Learning operates as CREVERSE Inc. (크레버스), one of the largest private K-12 education companies in South Korea, managing a multi-brand portfolio that includes Chungdahm Learning Center (flagship English tutoring), April Language Institute, iGARTEN (early childhood English), CMS Gifted Education Center and CMS Gakjaeyonggwan (gifted math/science), and C-Cube Coding (STEM). The company serves Korean elementary, middle, and high school students through a nationwide franchise network of branded academies, supplemented by Expression Learning Inc. as a wholly-owned subsidiary. Its core technology is the Smart Class platform, which synchronizes instructor and student tablets in real time for bidirectional classroom interaction, paired with proprietary TKS (Topic-Knowledge-Skill) methodology and a family of student apps (Play500, SELP, Buff, ChunkToon, Thinking MeMe, April learning portals) and content controls (Guardian) deployed on Samsung Galaxy Tab 10.1 hardware rented through the Learn21 materials portal.
The business model operates on three pillars: tuition and fees collected at branded academies (set independently by franchisees on a semester/monthly basis), franchise licensing fees paid by academy operators (가맹점) into the CREVERSE network, and complementary hardware/materials/online learning revenue (V ON Class, Learn21 e-commerce, PAD tablet rental at KRW 5,500/month). The company recruits students through entrance examinations, periodic admission information sessions, and parent explanation meetings, while parent communication runs through KakaoTalk channels and Naver blog/cafe communities.
Distribution spans all major Korean regions (Gangwon, Gyeonggi, Seoul, Busan, Jeju, Incheon, etc.) plus international academies in China. The company holds ETS authorization as a TOEFL Junior test center (valid January 2026 to January 2029), reinforcing its positioning on standardized English assessment. Ownership is privately held with no venture or PE capital signals in the source data, and the company is co-led by Representative Directors Lee Dong-hoon and Kim Hyung-jun.
