Established in 1989, the Appelbaum Training Institute has trained over 1 million educators throughout the United States and Canada, as well as in other countries of the world. We receive correspondence from home and abroad telling us how our seminars and online professional development, have helped teachers and children.

Children are the future of the world. Our mission to ensure that those who care for and teach our children are knowledgeable in techniques to guide children to be all they can be.

Our seminars and onsite trainings cover topics that relate to children and build a brighter future for them through you. We focus on presenting research and evidence-based materials that are considered "Best-Practice" in the field of education.

Our online professional development is affordable, easy to use, and allows users a self-paced format to advance their professional development and earn clock hours or continuing education credits.
