Assessment plays a crucial role in achieving learning objectives. The use of non-test assessments is still limited to the affective and psychomotor domains, whereas in science, particularly biology, assessment should cover all three domains to make the learning process meaningful. This research uses a qualitative descriptive method. The population consists of SMA Negeri 1 Ambarawa, SMA Negeri 1 Pardasuka, and SMA Negeri 1 Pagelaran, with purposive sampling as the sampling technique. Data collection techniques include interviews, observations, questionnaires, and documentation. Data validity is ensured through triangulation of data sources. Data analysis involves data reduction, data presentation, and drawing conclusions. The results of data collection through questionnaires show an average difficulty level. The observation results indicate no evidence of attached portfolios and projects. Meanwhile, interviews reveal difficulties due to a large number of students, limited time allocation, challenges in remembering each student’s attitude, difficulties in assessing self-honesty and peer assessment, the absence of specific instruments, many points to be assessed, complex instruments, insufficient socialization in instrument creation, lack of knowledge about IT, old age of teachers, and limited practical tools and materials.
