The source behind thousands of IB classrooms.
For 25 years, IB Source has helped IB World Schools put the right resources in teachers’ hands — textbooks, planners, digital tools and ready-to-teach lessons, curated from the publishers schools rely on.
We work shoulder-to-shoulder with schools, teachers and publishers, so finding, buying and using IB-aligned resources is the easiest part of your job.
Twenty-five years inside the IB ecosystem
IB Source began with a simple observation: IB teachers were spending too much time hunting for the right resources. For more than 25 years we’ve been fixing that — first as a specialist supplier of IB texts, today as a publishing partner woven into the fabric of the IB community.
From our Chicago headquarters, we supply individual classrooms, IB World Schools, and entire school districts across the United States and Canada — and dispatch to educators in more than 90 countries. Along the way we’ve grown from selling resources to building them: IB toolkits, ready-to-teach lessons, SEL programs, and custom publications designed around how IB classrooms actually work.
We also give back to the network that trusts us — supporting regional IB associations around the world and standing alongside educators at workshops, conferences, and curriculum launches.
