Calabash Professional Learning Systems is a part of the school division of Houghton Mifflin Company. Our job is to give teachers the knowledge and skills needed to improve student performance and foster a love for learning in mathematics and reading—the critical skills that underlie everything in their education.

Calabash creates and delivers professional development courses that are built on a respect for who teachers are and what they already know.

Our courses are flexible. They are materials-based and are linked to state standards and district goals. They are based on current, confirmed research. They are highly relevant to the challenges teachers face in the classroom every day.

Calabash's courses are led by seasoned teachers fresh from their own classrooms. The approach is systematic. The style is interactive and relaxed. Teachers walk out of every session with practical information they can use immediately.

Teachers want knowledge and skills that can be applied in the real world, NOW. That's what we give them.

Calabash: Houghton Mifflin does professional development.
