What Global Learners Are Saying

“[The Faith Matters Network Movement Chaplaincy Training Course] is essential for those in ministry and lay church leadership whether or not they are planning to be active in a specific movement chaplaincy. It offers a chance for all of us to see others with new tools and a new lens.”
Dr. Sushama Austin-Connor
Former Program Director
Black Theology & Leadership Institute, Princeton Theological Seminary
"I recently accepted the position as Director of Graduate Programs of our department. This requires interacting with international graduate students. I feel that taking part in the [Certificate in Global Citizenship] course helped me better relate to them and the backgrounds from which they come."

"I really enjoyed [Wildness & Spirituality for the Common Good]. I found it helped me work through my concept of wild(er)ess and find ways to regularly reconnect with the wild. Aram's reflections and the resources he provided were amazing. I will be using this information for years to come."

Frequently Asked Questions

Is this an accredited school?

The School of Global Citizenry (SGC) is an independent, online, global citizenship education (GCED) continuing education institution for adult learners. Tumbuh Global, its parent company, is a member in good standing with the Association of Leaders in Lifelong Learning for Ministry (formerly SACEM); affiliated with the Religious Education Association. SGC offers CEU approved trainings, courses, and virtual retreats. Most programs are adaptable for academic course credit (with prior approval). SGC does not confer academic degrees.

What does CEU mean?

CEU stands for continuing education unit. Religious, social, and civic leaders are often required to earn "CEUs" to show evidence of ongoing professional development. Our trainings, courses, and virtual retreats offer anywhere from 1-5 continuing education units. These are the same caliber CEUs offered by most Christian seminaries and divinity schools in the US. We do not confer CPE credits and are not yet APA-accredited. 

What is the Diamond Standard for CEU Certification?

The Diamond Standard™ is a research based accrediting standard for adult continuing education that ensures that our global learners are receiving quality education and training in a professional learning environment under the facilitation and leadership of proficient instructors and administrators. This standard weaves the core concepts of global citizenship education (GCED) together with the existing CEU standards of prominent institutional bodies for a robust learning experience specifically for postsecondary adult learners (PACE) from religious, social, and civic backgrounds.

What is global citizenship education (GCED)?

Global citizenship education (GCED) aims to equip individuals with the knowledge, skills, and attitudes necessary to actively engage in the global community as responsible and informed citizens. This type of education promotes intercultural understanding, respect for diversity, critical thinking, and social responsibility. 

Global citizenship education is important for adult learners because: 1) it provides them with the tools to navigate a rapidly changing and interconnected world, 2) it helps develop critical thinking skills which are essential for engaging with complex and pressing global issues, and 3) it fosters a sense of social responsibility.

What is the refund policy?

On-demand training and course purchases are non-refundable. Scheduled training, course, and virtual retreat refunds are available until the start date. If the program has already begun, no refunds are permitted. If, by chance, a scheduled program is cancelled, delayed, or rescheduled, you are entitled to a full refund (certain stipulations apply).
