Standardized tests in the English language are given in grades three and up, and in the Chinese language in grades two and up on a voluntary basis.

For the English tests, YHIS administers the Educational Records Bureau (ERB) Comprehensive Testing Program (CTP4). This is a rigorous testing program consisting of a Verbal Reasoning Test and Quantitative Reasoning Test. Students scores are normed according to annually updated national, independent school, and suburban school norms.

For the Chinese tests, YHIS administers the Young Learners Chinese Test (YCT) designed by the Chinese Language Council International (commonly known as “Hanban”). It is a test for non-native Chinese learners under the age of 15 that consists of Level 1, Level 2 and Level 3. Level 1 assesses youngsters who have studied Chinese for roughly 150 hours and mastered a vocabulary of about 500 characters. Level 2 assesses youngsters who have studied Chinese for roughly 250 hours and mastered a vocabulary of about 1100 characters. Level 3 assesses youngsters who have studied Chinese for roughly 400 hours and mastered a vocabulary of about 1700 characters.
