HSK stands for "Hanyu Shuiping Kaoshi," which is a standardized Chinese language proficiency test. It evaluates the skills of non-native Chinese speakers to use the Chinese language in their daily, academic, and professional life. The HSK test assesses competency in hearing, speaking, reading, and writing and is acknowledged as a trustworthy indicator of Chinese language proficiency by many institutions and businesses in China and other countries. It is separated into multiple levels, with HSK Level 1 being the most elementary and HSK Level 6 being the most advanced.
