Developing the ISO



One of our main activities is helping our 3 member organizations (Clarity, PLAIN, and the Center for Plain Language) develop a plain language standard with the International Organization for Standardization (ISO). We initiated ISO’s project to develop the plain language standard, created a workgroup to draft the standard, and advocate for the standard’s approval, adoption, and use. This standard will help people in all industries and nearly all languages develop and use more effective and equitable communication.

Here is a timeline of our work for the plain language standard. Learn more about the ISO standard, benefits of adopting the standard, and how to adopt the standard
