About
Amplify is a Brooklyn-based educational curriculum and technology company that develops research-backed core instructional programs for K-8 students. Its mCLASS reading assessment is the most widely used K-3 literacy diagnostic in the United States, and its CKLA (Core Knowledge Language Arts) and Amplify Science curricula are adopted by hundreds of school districts nationwide. Amplify's programs combine print and digital materials with real-time data dashboards that help teachers monitor student progress and identify students needing intervention. The company emerged from News Corp's education division in 2015 and has raised over $700M from investors including Chan Zuckerberg Initiative and IVP. Amplify focuses on evidence-based curricula aligned to the science of reading movement, which has driven adoption as districts shift away from balanced literacy approaches. It competes with Curriculum Associates, HMH, and McGraw-Hill.

About
i-Ready is an adaptive diagnostic and instructional program for K-8 reading and mathematics developed by Curriculum Associates, headquartered in North Billerica, Massachusetts. i-Ready is one of the most widely deployed educational assessment and intervention tools in US K-12 education, used in more than 40 percent of American school districts and serving tens of millions of students annually. The program combines a highly accurate adaptive diagnostic assessment with a personalized online instructional program, providing teachers and administrators with a complete picture of student reading and math performance along with targeted learning activities to address identified gaps.\n\nThe i-Ready diagnostic adapts its questions in real time to quickly and accurately identify each student's working level across specific skill domains — reading foundational skills, language, informational text, literary text, number and operations, algebra and algebraic thinking, measurement and data, and geometry — providing domain-level scores alongside an overall grade-level placement. This detailed diagnostic data is widely used by districts for universal screening, progress monitoring, and meeting federal requirements for identifying students who need intervention. The accompanying instructional program provides personalized online lessons targeted to each student's diagnostic results.\n\nCurriculum Associates has invested heavily in the research base for i-Ready, publishing studies demonstrating the diagnostic's predictive validity and the learning gains associated with the instructional program. i-Ready competes with Lexia, DreamBox, MAP Growth by NWEA, and STAR assessments by Renaissance Learning in the adaptive assessment and intervention market. Its dual function as both a diagnostic screener and instructional tool — combined with its extraordinary market penetration — make it one of the most influential platforms in US K-12 education.
