This document discusses various methods for testing English grammar. It begins by asking what aspects of grammar should be measured and whether the focus should be on structures, functions, usage, or descriptive vs. prescriptive rules. Common test formats are then outlined, including recognition through multiple choice, true/false, and gap-filling questions, as well as production through sentence building and editing exercises. The document recommends providing context and measuring a test-taker's ability to communicate grammatically for different audiences and tasks. Sample grammar testing activities are described, like split sentences, describing pictures, and story-building to evaluate understanding of various tenses and sentence construction.
