Current HSK / New HSK transition
Use the exam path confirmed by your test center
The official New HSK syllabus was published in November 2025 and identifies July 2026 as its effective date. The syllabus effective date does not mean every test center switched every regular examination on one date. ACA provides New HSK courseware for Levels 1-6 and advanced 7-9 A/B/C tracks while continuing to support current HSK preparation. The first two lessons in every track are free to study.
