The government of Taipei City, Taipei County and Keelung City announced their "one-guideline-one-version policy" and "Joint sponsorship of basic skills achievement tests for junior high school students." Due to "one-guideline-one-version policy" against the "one-guideline-multiple-versions" principal of national education act, the policy has become a dispute between local governments versus the ministry of education. Furthermore, this dispute exactly reflect the custom of administrations, that the administrations prefer using informal way to legal way. To analyze those disputes in legal study, we use the constitutional protection of education basic right to verify the justification and appropriateness of the one-guideline-one-version policy, since the constitution is generally held to contain basic society values. Moreover we use principle of rule of law and theories of judicial review to undertake a legal analysis of that policy.
