Research shows communities and organizations using trauma informed practices are reporting significant benefits related to staff and client satisfaction and program outcomes.


A Peaceful Households ACE Master Trainer is authorized to educate others on ACEs and trauma using Peaceful Households proprietary materials. Under no circumstances is the ACE Master Trainer authorized to let other individuals use the ACE Master Training materials nor is the ACE Master Trainer allowed to transfer the rights to the materials to another  individual or organization.

A refresher course is required every two years for individuals to maintain the Peaceful Households ACE Master Trainer status and continue use of proprietary materials.

Peaceful Households periodically updates training materials based on the most recent research, best practices, data and experiences.  These materials are made available to ACE Master Trainers either through refresher courses or as downloads as they become available. All updated materials and refresher courses are available for a fee and are not included in the cost of the initial training course.
