Based on the latest official guidelines (2025), here’s a structured overview of how HSK credentials work, covering certificate permanence, score expiration rules, and retake policies:

1. HSK Certificate Validity

2. HSK Score Validity

3. Retaking the HSK Exam

Key Comparison Table

Aspect	HSK Certificate	HSK Scores (for academic use)
Validity Period	Permanent (no expiration)	2 years from the test date
Primary Applications	Work permits, professional credentials	University admissions
Retake Policy	Not applicable (one-time award)	Unlimited retakes allowed

Important Considerations

While the certificate itself is permanent, always verify specific requirements with your target university or employer. Some institutions may have additional criteria, such as requiring scores to remain valid through the program start date or specifying minimum score thresholds for certain majors.

This framework helps test-takers navigate credential use effectively, balancing long-term professional proof with time-sensitive academic requirements.
