This document discusses approaches to assessment in task-based language teaching. It outlines key concepts like the differences between evaluation, assessment, and testing. Assessment in task-based language teaching should reflect what has been taught through direct, performance-based measures rather than indirect tests. Both direct and indirect assessments have benefits, as do criterion-referenced and norm-referenced tests. Task-based assessment requires learners to complete authentic language tasks. The purposes, techniques, and criteria for assessing learner performance in task-based language teaching are also covered.
