This summary provides an overview of two units on language testing and assessment:
Unit B4 discusses test specification design, including elements that should be included like samples and guiding language. It also examines the distinction between prompt and response attributes.
Unit C4 focuses on how test specifications evolve over time. It provides examples of a role-play assessment and how the scoring criteria and use of written plans changed between versions as instructors debated and tested the requirements. The unit proposes applying a reverse engineering workshop to critically analyze existing test tasks and improve testing practices.
