自民國101年1月1日起，臺灣幼托整合正式啟動，其發展歷程已有一段歷史軌跡，本研究從探討幼兒園師資角度，以大數據資料分析101學年度至109學年度臺灣幼托整合後的幼兒園教師整體素質，其研究結果發現：（一）幼兒園經費支出佔各級學校經費總支出7~8%；（二）105學年度幼兒園數量創歷史新低；（三）107學年度幼兒園園長人數為最低峰，教師、教保員與助理教保員於109學年度達漲幅高峰；（四）臺灣幼兒園在職教師以「40‒44歲」為多數；（五）男性教師與男性教保員年年正成長；（六）「碩士」與「博士」學歷者均持續增加，且108學年度漲幅最多。最後依據現況，提出具體建議，以供未來研究參考。

Starting from January 1, 2012, the policy of the integration of kindergartens and nursery schools was initiated in Taiwan. As this policy has been implemented for almost 10 years, this study attempted to investigate the overall quality of preschool teachers by conducting the analysis of big data from the academic year of 2012 to 2020. The results are as the followings: (1) Preschools’ Expenditure accounted for 7‒8% of the expenditures of schools at all levels; (2) The number of preschools hit a record low in the academic year of 2016; (3) The number of preschool directors hit a record low in the academic year of 2018, whereas preschool teachers, educare givers, and educare assistants reached a peak increase in the academic year of 2020; (4) Most in-service preschool teachers are aged 40‒44 years; (5) The numbers of male teachers and male educare givers show an increasing trend; and (6) The number of preschool teachers with a Master’s or Doctoral degree is increasing, with the largest increase occurred in the academic year of 2019. According to the research results and the current situation, this study proposed recommendations and served as a reference for future studies.
