Creative coding offers the opportunity to express oneself on open-ended coding platforms through artistic expression, storytelling, and experimenting with program syntax in unconventional ways. However, research on the creative aspects of coding education and its assessment remain underexplored. This study addresses this gap by developing and validating a Creative Coding Rubric tailored for early childhood creative coding projects. Our study collected and analyzed ScratchJr projects from 1201 children in grades K-2, revealing substantial agreement among raters (n = 15) for the rubric. Additionally, significant positive correlations among rubric items and high reliability (α = .93) indicate its validity and consistency. This Creative Coding Rubric presents a promising tool for early childhood educational settings to evaluate creative coding skills in playful, open-ended ways.
