GCA: A Platform and Marketplace for Upskilling Professionals and Educators Serving Children GCA helps professionals and educators serving children upskill and achieve their professional career goals. We are dedicated to creating an ecosystem that connects adult learners with vetted training providers and thought leaders from around the world. Our platform is designed to bring together stakeholders who are committed to making a lasting impact on society. At the Global Childhood Academy (GCA), we are dedicated to supporting and advocating for children. We believe that adults and professionals have a responsibility to protect and care for children, and we are focused on providing training and skills development opportunities for these adults. Based in the United States, our mission is to create a global ecosystem for individuals and groups who work with or serve children between the ages of birth and 18.
