This collection of photocopiable tests serves as a standardized assessment tool designed to measure student progress within the Collins COBUILD English Course framework. The authors, Dave Willis, Diana L. Fried-Booth, and Jane Willis, utilize the linguistic research foundational to the COBUILD dictionary to ensure that assessment items reflect authentic, everyday English usage. The material provides a structured evaluation system for adult learners transitioning from false beginner levels toward pre-First Certificate proficiency.

The material functions as a technical supplement for instructors utilizing the COBUILD curriculum, providing a standardized method for gauging student acquisition of core language competencies. Its utility is defined by its direct integration with the broader course research, offering a consistent evaluative experience for adult learners.
