The problem in this study is that the initial reading ability of children aged 5-6 years has not developed optimally. This study aims to determine the influence of letter-arrangement media on early reading skills of 5-6-year-old children at TK Xaverius 3 Bandar Lampung in the 2024/2025 academic year. The research method used is a quantitative approach with a quasi-experimental design in the form of a one-group pretest-posttest design. The subjects of this study were 26 children in Group B. Data collection was carried out through early reading skill observation conducted before and after the intervention using letter-arrangement media. The data analysis techniques included normality test, and hypothesis testing using the Paired Sample T-Test. The results showed a significant difference between the pretest and posttest scores. This was proven by the t-count value of -32.212 and a significance value of < 0.001 (p < 0.05), thus the alternative hypothesis (Ha) was accepted. Therefore, the use of letter-arrangement media significantly influenced the improvement of early reading skills in children aged 5-6 years. The use of letter-arrangement media has been proven to stimulate children in helping children recognize letters, form syllables, and read simple words more easily.
