This study was motivated by the importance of developing discipline as a character trait in early childhood through habituation activities implemented consistently within the educational environment. One of the approaches implemented is the Seven Great Habits Program, which includes the habits of waking up early, practicing religious activities, exercising, consuming healthy and nutritious food, developing a love of learning, engaging in community activities, and going to bed early. This study aimed to describe the implementation of the Seven Great Habits Program, determine the level of discipline among young children, and analyze the effect of the program on early childhood discipline at PAUD Melati 01 Tanjung Priok, North Jakarta. A quantitative approach was employed, involving 52 children as respondents. Data were collected using research instruments and analyzed using descriptive statistics, a Paired Samples t-Test, and simple linear regression. The results showed that the mean score increased from 31.21 before the implementation of the program to 73.58 after its implementation, with a mean increase of 42.37 points. The Paired Samples t-Test yielded a value of t = −23.417, with df = 51 and a significance level of 0.000 < 0.05, indicating a significant difference before and after the implementation of the program. The results of the simple linear regression analysis showed a regression coefficient of 0.906, a t-value of 7.531, and a significance level of 0.000 < 0.05, with the regression equation Y = 45.31 + 0.906X. Therefore, the Seven Great Habits Program has a positive and significant effect on early childhood discipline.
