This study aims to determine the correlation between parenting styles and the learning achievement of Generation Alpha children aged 4–5 years in early childhood education (ECE) institutions in Tuak Daun Merah Village, Kupang City. The parenting styles examined in this study focused on helicopter parenting, characterized by excessive supervision, control, and protection, and gentle parenting, which emphasizes empathy, positive communication, and children’s independence. This study employed a quantitative approach using a correlational research design with a cross-sectional method. Data on parenting styles were collected through questionnaires, while children’s learning achievement was assessed using developmental assessment sheets completed by classroom teachers through a rating scale. The sample consisted of 40 children and their parents from four ECE institutions located in Tuak Daun Merah Village, Oebobo District, Kupang City, East Nusa Tenggara. Data were analyzed using the Spearman Rank correlation test. The results showed that both fathers’ and mothers’ parenting styles tended to be more dominant in gentle parenting than in helicopter parenting. The highest level of children’s learning achievement was found in the Pancasila values aspect at 75%, while the lowest was found in the cognitive aspect at 67%. The correlation test results indicated that there was no significant relationship between fathers’ parenting styles and children’s learning achievement (rₛ = −0.026; p = 0.873), nor between mothers’ parenting styles and children’s learning achievement (rₛ = −0.028; p = 0.863). Overall, the findings showed no significant relationship between parental parenting styles and the learning achievement of Generation Alpha children aged 4–5 years (rₛ = −0.007; p = 0.967).
