Communicative language testing is intended to provide information about a test taker's ability to perform tasks using the target language in specific contexts. Developing useful communicative tests presents difficulties like creating frameworks that balance communicative teaching goals with test design principles. Reliability and validity are important, requiring consistent measurement and ensuring the test accurately measures what it intends to. Tips for developing communicative tests include starting simply, focusing on content, considering test impact, allowing for context specificity, and acknowledging the multidimensional nature of language. Examples of communicative tests are information gap activities, letter writing, and note taking.
