HSK 2.0 / 3.0 transition
Current courses align with the HSK 2.0 path while HSK 3.0 mapping is being prepared
HSK 3.0 became the global standard on July 1, 2026. ACA keeps the current HSK1-HSK4 route usable during the 2026 transition year and is preparing a new-level mapping so learners can see how each lesson connects to the updated standard.
