This paper evaluates current assessment methods in architectural design studios and proposes a criteria-based approach to enhance evaluation processes. The study utilizes a literature review and case studies to analyze existing practices and highlights the importance of transparent and fair evaluations. By implementing a standardized model with clearly defined assessment criteria, students gain a better understanding of expectations and parameters, fostering creativity and minimizing subjective evaluations. The research emphasizes the significance of promoting students' mental and emotional well-being by providing a clear understanding of assessment processes, thereby reducing stress and anxiety.The findings demonstrate a notable improvement in the consistency of evaluations between instructors and guide assessments. Initially, there was a mean deviation of 32.42% between the assessments made by instructors and guide

assessments. However, after implementing the criteria-based evaluation approach, this mean deviation significantly reduced to 8.55%, indicating a more aligned and objective assessment process. The study also includes the results of a poll on self-assessment tasks, where 70% of students acknowledged the positive contribution of self-assessment to project quality. Moreover, 68% of students reported enhanced abilities to provide constructive feedback on their peers' projects through self-assessment, Overall, the study underscores the need for a criteria-based approach in architectural design studios, as it promotes evaluation consistency,quality improvement,and student learning experiences. Furthermore, the research suggests that with further practice and training, the criteria-based evaluation approach can be refined, leading to even more consistent evaluations among assessors.
