This paper focuses on faculty training facilities at private elementary schools in Okayama Prefecture following the end of WWI, primarily between 1920 and 1922. It also contributes fresh perspective to the literature on the means by which elementary school teachers were trained, using a route other than that of normal schools in prewar Japan. The author has thus far researched the elementary school teacher training business in private elementary faculty training facilities in Okayama which began in the 1900s following the establishment of a compulsory four-year education system. As a continuation of that research, this paper focuses on the end of WWI, a period marked by the decline of elementary school teachers following the wartime climate. It focuses on the significance of and manner in which private elementary school training facilities emerged in the form of authorized secondary education test training facilities for faculty, thereby securing their continuation amidst the withdrawal and decline of private elementary faculty training facilities. This phenomenon suggests that a proper evaluation of primary education faculty training requires incorporating secondary education faculty training into the scope of research.
