Trainers In-Training are required to attend Tier II training, submit materials for feedback and evaluation, pass certification and clear any requirements outlined in their individual certification letter in order to provide Tier I Project GLAD® Training (2-Day Research & Theory Workshops, 4 or 5-Day Demonstration Lesson, Follow-up and Awareness Presentations) as a Project GLAD® Agency Trainer (Tier III). Individuals working for an educational agency other than a school district must file an Authorization to Train Addendum with the National Training Center. This advanced Research and Theory session strengthens an established understanding of how language is acquired and promoted in the classroom based upon contemporary research and the research which was used to develop the Project GLAD® model. Trainers in-training will observe the Research and Theory training through the lens of what they will be expected to do upon becoming a certified trainer.
