The Confucius Institute at the University of Hawaii at Manoa (CI-UHM), a program of the Center for Chinese Studies, UHM, has in the past offered the HSK (Hanyu Shuiping Kaoshi) standardized Chinese language proficiency test (both oral test and written test) to UHM students and members of the public, and the YCT (Youth Chinese Test) to public and private elementary and high school students.
The tests are offered worldwide through the auspices of Hanban (Confucius Institute Headquarters).
More information about Hanban is available here: http://english.hanban.org/node_7719.htm.
Due to low demand, the CI-UHM is currently referring interested parties to the Mun Lun School, which offers the HSK and YCT for its own students, and can accommodate others. Please contact Principal Chock Wong at 808-551-5120, or firstname.lastname@example.org
More information about the oral and written HSK and YCT and their different levels; practice tests; a FAQ; and online registration are all available through the following website, www.chinesetesting.cn.
