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.
Unified K-12 school-home communication platform replacing fragmented parent apps for 2M+ families. Santa Barbara CA; raised $200M+; serves districts automating newsletters, alerts, and two-way teacher-parent messaging at scale.
About
ParentSquare is a unified school-home communications platform designed to replace the fragmented combination of email, robocalls, apps, and paper notices that districts use to communicate with families. Founded in 2011 and headquartered in Santa Barbara, California, ParentSquare has raised more than $200 million from investors including Owl Ventures and General Atlantic, and has grown to serve more than 20 million parents across thousands of school districts in the United States. The company's platform consolidates district-to-family communication — including emergency notifications, classroom updates, permission slips, event signups, and two-way messaging — into a single app that families can use in their preferred language.\n\nParentSquare's multilingual capabilities are a key differentiator, with automatic translation supporting more than 100 languages that allows teachers and administrators to send communications that are automatically translated for non-English-speaking families, dramatically improving equity of access for the diverse communities that many districts serve. The platform supports communication at every level — from the superintendent communicating district-wide to the individual classroom teacher sending a note about a homework assignment — with consistent branding and a single app experience for families regardless of which school their children attend.\n\nParentSquare competes with Bloomz, Remind (acquired by ParentSquare), and ClassDojo in the parent communication space, and with broader district communication platforms like SchoolMessenger. Its acquisitions of Remind and other tools have strengthened its position as the most comprehensive K-12 family engagement platform. The company differentiates through its depth of features, multilingual support, integration with student information systems, and the breadth of district deployment from small rural schools to large urban districts.
