About Sadlier School

In today’s high-performing schools, Sadlier is the go-to publisher to partner with for your English Language Arts and Mathematics academic needs. Our traditional approach to teaching core curriculum content has been proven effective for decades to truly prepare students for the demands of college-level work and life.

As a smaller publisher, we work closely with our customers to understand their unique needs and provide innovative solutions for instruction in the classroom and out. This is seen in our well-respected products—such as Vocabulary Workshop and Progress in Mathematics—that we’ve improved over time to support the ever-changing needs of the classroom.

It is the trust in the Sadlier quality that keeps loyal customers returning year after year. They know we’ll always be tied to solid educational content and a commitment to what works.

History

Back in 1832, two brothers, Denis and James Sadlier, immigrants from Ireland, began publishing materials to meet both the spiritual and educational needs of the Irish immigrant community. This began the story of William H. Sadlier, Inc. and an entrepreneurial, family-owned company that would be passed down across the generations and would continue to innovate and publish educational resources that students and educators were in demand of.

Over the years, Sadlier created history and geography programs that were groundbreaking in their day. Sadlier’s The Old World and American History represented a new approach that would revolutionize the way educators taught history in elementary schools. Years later, Sadlier continued to innovate by publishing the Social Geography Series. The success of that series was felt across public schools and sustained the company during the great depression.

With the acquisition of the Oxford Book Company in 1972, Sadlier achieved its mission of publishing textbooks in all major academic areas. Today, we are the trusted partner and solution provider to thousands of private and public schools across the world. Sadlier has produced award-winning Math, Language Arts, and Literacy educational programs that are customized to the needs of every type of learner. Our programs reach a diverse audience and have been adopted by large states, as well as individual teachers in schools across the world.

In schools today, Sadlier is often referred to as the Vocabulary Experts. Our Vocabulary Workshop programs are the leaders in their category, known as trusted resources that help high-achieving students expand their vocabularies, improve word acquisition skills, and prepare for standardized tests and academic success in college. The new Vocabulary for Success helps at- or below-level students and English Language Learners develop the vocabulary they need to succeed.

Sadlier’s ongoing success has been tied to our ability to change with the times to meet the present-day needs of educators and students. That’s why we developed the new Sadlier Connect, a single sign-on, Web-based platform with access to program resources. Educators, students, and parents can find Interactive Editions, eBooks, and Online Assessments that provide instant feedback, automatic scoring, and a robust reporting system to help track student achievement.

The current Chairman of the Board, Frank Sadlier Dinger, and President William Sadlier Dinger, are the great-grandsons of William H. Sadlier and direct descendants of Denis and James Sadlier. They’ve been recognized as leaders in educational publishing by the Association of Educational Publishers (AEP) and have been inducted into the association’s prestigious Hall of Fame for their lifetime of achievement, commitment, and dedication to education.

For over 185 years, the Sadlier family has nurtured William H. Sadlier’s original vision with integrity, creativity, and a commitment to ongoing excellence. That family tradition is felt today and will continue to help us serve our customers into the future.
