transform from conventional assessment methods to digital assessments that are more adaptive, effective, and capable of increasing students’ learning motivation. However, field realities show that many teachers at MTs Nurul Huda Babadan, Ngajum District, Malang Regency, are still accustomed to rigid and less engaging paper-based daily assessments. This study aims to improve teachers’ competence in developing effective and enjoyable daily assessments through the use of web-based applications. The method employed is Participatory Action Research (PAR) in the form of intensive training and mentoring. The training involved 28 subject teachers at MTs Nurul Huda Babadan, Ngajum District, Malang Regency. The activities were divided into three stages: (1) socialization and pre-test on the concepts of formative assessment and gamification; (2) a workshop on developing assessments using a web application (Zep Quiz); and (3) implementation mentoring and post-test. Data were collected through pre-tests, post-tests, product analysis (assessment instruments), and response questionnaires. The results show a significant increase in teachers’ conceptual understanding and technical skills. The average pre-test score was 60.2, which increased sharply to 87.5 in the post-test. Product analysis indicates that 87.5% of teachers successfully designed at least one web-based daily assessment instrument that was content-valid and integrated gamification elements. Teacher responses show that 94% considered the training highly relevant and impactful for their teaching practice. This training successfully transformed teachers’ paradigms from assessors to facilitators of motivating assessment.
