Western educational policies and practices have impacted Taiwanese early childhood programs. The concept of developmentally appropriate practice has become part of the educational program for young children in Taiwan. This research study was completed to: (a) describe Taiwanese parents' beliefs about developmentally appropriate practice (DAP) in early childhood programs; (b) examine group differences between fathers' and mothers' beliefs about DAP; (c) investigate group differences between parents of different socioeconomic statuses beliefs about DAP; (d) explore group differences between parents' beliefs about DAP when their children attend different types of schools (public and private); and (e) identify salient factors related to the variability of developmentally appropriate beliefs of Taiwanese parents. Three hundred seventy-nine matched Taiwanese parent pairs (mothers and fathers) participated in this survey research study. All parents had at least one child between the ages of 3 and 6 years. Four hundred forty-eight children attended public schools, and 415 attended private schools. The Teacher Beliefs Questionnaire was modified and used to collect data in this study. Findings showed: (a) fathers' and mothers' beliefs about DAP are significantly correlated; (b) fathers' and mothers' socioeconomic statuses are significantly correlated with their developmentally inappropriate practice beliefs; and (c) parents' socioeconomic status was a significant predictor of their DAP belief scores and family, culture, and inclusion belief scores. Future studies are needed to determine the effectiveness and appropriateness of the Teacher Beliefs Questionnaire with Taiwanese parents. Including parent's age, child's gender, child's birth order, residential region, and number of children as variables in future research studies may explain variations in parents' DAP beliefs. Employing qualitative methods, such as classroom observations, case studies, and interviews may be used to verify these findings. The Taiwanese Ministries of Education and Interior may find this study's results useful in creating policies and best practices related to the education of young children. Teachers may use these results to guide their work with parents.
