Based on the survey results of 150 South Korea toddler caregivers about training needs, I developed a relationship-based approach for a toddler caregiver training program. The training program was modified using suggestions provided by 6 South Korean professors, who were asked to review the program. Survey findings revealed that: (a) All participants (toddler caregivers) perceived that it is necessary for caregivers to attend training. However, most (72.2%) found that it was difficult to attend training programs more than 1 time per year because it was hard to find a substitute teacher (64%). Participants desired to attend training programs on toddler care because of the lack of in-service education (26%), curriculum (24%), and training programs (15.3%); (b) Caregivers who had the third-degree caregiver certification preferred to learn parent education more than child development. However, caregivers who had a higher degree of caregiver certification preferred to learn child development more than parent education; and (c) Caregivers who had more than 5 years of teaching experience preferred to learn about the teacher's role more than caregivers who had fewer than 4 years of teaching experience. Future studies need to evaluate the effect of this relationship-based training program for toddler caregivers in relation to improvement in the quality of child care and interaction between caregivers and toddlers. A large-scale study would increase the generalizability of research findings. A larger sample size from different cities in South Korea and random sampling would generate more reliable findings.
