2. Company History and Business Evolution

Curriculum Associates began in 1969 as a small educational publishing house founded by William J. Callahan and his wife, Claire. Initially focused on supplemental print materials like workbooks and teacher guides, the company quickly gained a reputation for high-quality, research-based content. The turning point came in the late 1990s when digital learning began to reshape education. Curriculum Associates launched its first online assessment tool, the CORE Reading and Math programs, which paved the way for the development of i-Ready in 2011. i-Ready revolutionized the company by combining adaptive diagnostic tests with a cloud-based instruction engine that personalizes learning for each student. Over the next decade, Curriculum Associates expanded its product suite to include Ready Mathematics, Ready Reading, and the Teacher Toolbox, a digital resource library. The company also embraced professional development, creating the i-Ready Central platform for teacher training. In 2020, amid the COVID-19 pandemic, Curriculum Associates responded rapidly by making i-Ready accessible for remote learning, leading to a surge in adoption. Recent milestones include the launch of i-Ready Classroom Mathematics in 2021 and the introduction of Spanish-language versions of key products.
