I Used the Creative Commons PESO® Graphic Before—What Now? (Legacy Use Guidance)

TL;DR: We previously offered the PESO Model® graphic under Creative Commons, but it is now governed by licensing terms to protect integrity and consistency.
 

If you’re continuing to use the graphic, confirm your license type (Educational, Academic, Professional, or Enterprise) and update your materials to comply with current rules (official file, no modifications/derivatives/recreation/partial use, attribution/backlink, and trademark usage).
