Students in Chinese independent high schools take standardised tests known as the Unified Examination Certificate (UEC) at the end of Junior Middle 3 and Senior Middle 3. UEC has been run by UCSCAM since 1975 and has won ISO9001 certification from Malaysia, China, UK, Japan and so on. The UEC is available in three levels: Vocational Unified Exam (UEC-V), UEC Junior Middle Level (UEC-JML/JUEC) and Senior Middle Level (UEC-SML/SUEC). The syllabus and examinations for the UEC-V and UEC-JML are only available in the Chinese language. The UEC-SML has questions for mathematics, sciences (biology, chemistry and physics), bookkeeping, accounting and commerce in both Chinese and English.
