Plain language practitioners began formally discussing options for creating an international standard in 2007.

You can read a timeline about how plain language experts first proposed and then developed the standard. At several points along that timeline, the international plain language organizations provided updates and encouraged people to be involved in ISO’s process.

In a 2018 edition of The Clarity Journal (number 79), people were invited to support the standard and to participate in developing it. Some of the people who came forward at that time, and later, became actively involved in the work.
