Logically speaking, it might seem reasonable to expect that the nine-year integrated curriculum would have to be built from the ground floor up, starting with first grade and advancing one year at a time all the way until ninth grade (i.e. the third year of junior high), with the entire process of its implementation taking nine years.
從制度上討論，如果九年一貫要循序漸進，從一年級到九年級（國三）逐年實施，必須花上九個年頭才能完成。
