Abstract
Learning and assessment are an inseparable whole. Assessment, if designed appropriately, thoroughly and used appropriately in assessment procedures, can contribute to effective learning and have an impact on the competence of quality students. This study aims to analyze the need for project-based authentic assessment of teachers in elementary schools. This research includes descriptive qualitative research on elementary school teachers in Banjarnegara Regency, Central Java. Data was collected through literature studies of reputable international articles indexed by Scopus and field studies through questionnaires distributed to 103 elementary school teachers, interviews, and documentation studies of 10 elementary school teachers. Data analysis using the Miles and Huberman model includes: data collection, data reduction, data presentation, and conclusions. The results of the study showed that the majority of teachers' assessments focused on the knowledge aspect using a multiple-choice test, the attitude aspect using observation, and the skill aspect using project assessment. Due to a lack of references, teachers struggle to develop assessment instruments and thus lack a clear rubric. The conclusion of this study is that teachers have difficulty implementing project-based authentic assessments so they need a practical authentic assessment companion book.
