This document presents a framework for researching classroom-based assessment processes based on a study of Indonesian language classrooms in Australia. The framework addresses gaps in previous research by considering epistemological bases for assessment practices and focusing on learners and learning. It defines classroom-based assessment broadly to include diverse informal data. The study used ethnographic methods to analyze four key assessment processes: planning, framing for students, conducting, and using assessment data. It investigated what teachers look for in student work and what standards they apply.
