"It works! It's taught by leaders in the trenches who are interacting with TCKs on a daily basis." - Jan 25 cohort alumni
"Just do it. I heard classmates from different backgrounds and experiences say how beneficial the information was. There were weeks when the outside work took longer, but none of it was difficult. Every assignment had practical applications and allowed me to immediately use what I was a learning in an intentional way. Getting the feedback for each assignment was not only helpful but very encouraging!"
