About Perfection Learning®

Founded by two educators in 1926, Perfection Learning® provides high-quality, innovative curriculum solutions to K-12 schools across the country and internationally.

For more than 90 years, Perfection Learning® has been a leader in literature and language arts programs for grades 6–12. These programs cover the complete range of language arts skills and course areas with both textbooks and supplemental programs. Innovative, inquiry-based literature programs provide cost-effective solutions for teaching close reading and writing, developing critical thinking skills, and building literacy engagement—all while incorporating the demands of state standards. Grades K-8 reading/language arts solutions include hybrid print/digital handwriting and spelling programs, supplemental middle school literature programs, and intervention programs in reading and math.

Perfection Learning® is also one of the leading providers of trade books to classrooms across the country and delivers an unsurpassed selection of novels, nonfiction books, classroom collections, and literature-based teaching support.

In 2013, Perfection Learning® acquired AMSCO School Publications. For more than 75 years, AMSCO has excelled in providing high-quality materials in social studies; AP®, ACT, and SAT preparation; world languages; science; language arts; and more. All of us at Perfection Learning are pleased to continue this tradition.
