The findings of this study are as follows: 1. The existing Supplementary Education Act does not prohibit short-term tutorial centers from taking care of young children under six years old full-time; 2. in accordance with the Supplementary Education Act, short-term tutorial centers managing preschool-like educare services should be penalized, but not in accordance with the Early Childhood Education and Care Act. Based on the findings, this study offered the following suggestions: 1. adapting the Supplementary Education Act to prohibit short-term tutorial centers from taking care of young children under six years old full-time; 2. implementing a Supplementary Education Act to rehabilitate the establishment of business permit; 3. establishing penal provisions in local self-government ordinances to prohibit short-term tutorial centers from managing preschool-like educare services.
