The HSK 3 certificate is valid indefinitely as a record of language proficiency, but if used as proof of Chinese language ability for foreign students applying to Chinese universities, it is valid for two years from the examination date. Here are the details:

- Long-term Validity of the Certificate: The HSK 3 certificate, like other HSK certificates, does not have an expiration date for demonstrating language proficiency. It serves as a permanent record of the candidate’s Chinese language level at the time of the exam.

- Two-year Validity for University Admission: When the HSK 3 certificate is used as proof of Chinese language ability for foreign students applying to Chinese universities, it is generally considered valid for two years from the examination date. This means that if a student plans to use their HSK 3 certificate to apply for university admission, they should ensure that the certificate was obtained within the past two years.
