Tween/c21 Student Publishing is an indie provider of innovative college readiness resources. Our programs help students around the globe build college readiness skills. Our ultimate mission is to unlock the full 21st century potential of every student.

Our Mission

Our curriculum focuses on real world 21st century skills. We partner with teachers and administrators to bring essential 21st century knowledge into the classroom to improve the lives of all students.

Our other mission? Give teachers a break!

These days, most teachers have too many responsibilities in the classroom and too many demands on their time to be able to create their own curriculum. Each of our programs is the result of thousands of hours of design, research, writing and rewriting. This painstaking approach to curriculum creation has resulted in fully turnkey, comprehensive and easy to teach programs. You can also upgrade your order to include the Instructional ToolKit with podcasts, classroom slides, vocabulary flashcards, and more to make teaching a breeze. They’re also easy on the budget.

Globe shape with "Learning is Fun"

Who says serious learning can’t be accomplished with a few smiles?

Whether it’s work habits and time management, financial literacy, study skills, or college knowledge, our resources are student-friendly with comics, cartoons, and fun trivia to engage and maintain students’ interest from start to finish in every lesson.
