The purposes of this paper are to examine drafts of High School Establishment Standard enacted in January 1948 and to make clear how the high-label class size standard in the Standard had been established and how the measures for meeting the standard had been designed. This paper clarifies two points. First, the class size standard was designed by the Secondary School Standards Committee against Monta L. Osborne (Civil Information and Education Section, CIE) at the early stage of the process for making the Standard. The Ministry of Education carried on drafting it and steadfastly maintained the class size standard while conceding on establishment, correction, or deletion of the other provisions. Second, the Committee had suggested a two-level standard system (the permanent standard and tentative standard). This two-level standard system underscored the tentative standard as the minimum standard and requested schools meeting the tentative standard that they aim to meet the permanent standard. However, the Ministry deleted all provisions about the system. This drafting process seems to have brought about the emasculation of the permanent standard.
