The present study is triggered by the implementation of the achievement assessment system and the 2009 revised national curriculum, and the consequential need to help teachers to understand the new version of the curriculum when carrying out the achievement standard-based evaluation at school. The present study focuses on the newly introduced advanced courses of the 2009 revised national curriculum of English and provides an analysis of the hierarchical and interconnected relationship among these courses and the organization of their achievement standards. The study also provides guidelines for teachers on refining and customizing the curriculum-based achievement standards of the advanced English courses, for their own evaluation activities at school. Based on the analysis, the study attempts to suggest directions for the successful implementation of the new assessment system.
