About Us

The School of Global Citizenry, a program of Tumbuh Global, is an independent, CEU certified, global citizenship education (GCED) online school of lifelong learning for adult learners from religious, social, and civic backgrounds and a training center for new and emerging online educators. Prior to founding The School of Global Citizenry, we analyzed two years worth of research on and experience with adult learners, spent six months researching and analyzing the independent continuing education standards of the most prominent seminaries, divinity schools, judicatories, and denominations in the United States of America, and conducted a pre-COVID analysis of existing online learning platforms. And with this analysis and a decade of experience with adult spiritual formation and training in adult learning theory, we developed The Diamond Standard™ for CEU Certification. A continuing education quality standard that either meets or exceeded the requirements of the schools, organizationals, and denominational bodies in our study.

 The Diamond Standard™ for CEU Certification is a research based quality standard for adult lifelong learning. This standard ensures that global learners are receiving quality education and training in a CEU certified learning environment under the facilitation and leadership of CEU qualified instructors and administrators. In other words, we took the existing independent standards of prominent institutions and created the most comprehensive set of CEU qualifications currently available. By establishing industry qualifications for CEU approved instruction and requiring that all of our educators meet those standards, we raise the standard for adult lifelong learning and the standard for those administering similar content to ensure quality continuing education learning is available to all. 

The Diamond Standard™ for CEU Certification also integrates the core concepts of UNESCO’s global citizenship education together with the latest research in adult online learning for a robust learning experience specifically for postgraduate adult learners from religious, social, and civic backgrounds. It is truly diamond quality.

Frequently Asked Questions

We are a member in good standing with the Association of Leaders in Lifelong Learning for Ministry, the Religious Education Association, and the Council for Global Citizenship Education. 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 lifelong learning 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.
