Clear Communication Index Scoring Widget
The CDC Clear Communication Index is a research-based tool to help you develop and assess public communication materials. The 20 items in the index build on and expand plain language techniques described in the Federal Plain Language Guidelines. The Index goes beyond checklists and readability formulas by focusing on the most important research-based items that enhance clarity and aid understanding. The index also provides a numerical score so you can objectively assess and improve materials based on the best available science.
