Education Technology · Profile from Education Technology Research Companion
Curriculum Associates, LLC
A Massachusetts K-8 publisher founded in 1969 that sold print workbooks for four decades. Under Rob Waldron from 2008 it turned into the maker of i-Ready, the adaptive diagnostic and personalized-instruction platform now used by roughly a third of US elementary and middle-school students. It is privately held by private equity (Berkshire Partners, Permira, Hellman & Friedman), founder-linked philanthropy and employees, and is unusual for the way founder and CEO wealth has been given to charities and to staff.
At a glance
- Founded
- 1969, by two Boston University School of Education graduates who had taught in Wellesley, Massachusetts; started in a garage
- Founders
- The two original teacher-founders. Frank Ferguson, who lent the founders ~$10,000, became co-founder and chairman and ran the company from 1976 to 2008
- Headquarters
- North Billerica, Massachusetts; large offices in Raleigh-Durham and other US hubs
- Ownership / structure
- Private LLC. Berkshire Partners acquired control in 2017 in a transaction tied to the Ferguson philanthropy; Permira and Berkshire were described as majority shareholders by January 2022, when Hellman & Friedman (H&F) bought a minority stake. Employees hold stock, including a ~$100m gift from Rob and Jennifer Waldron in 2023. Not employee-owned in the ESOP sense
- Leadership (2026)
- Kelly Sia, CEO since January 1, 2025 (formerly President; earlier at Procter & Gamble and Iron Mountain). Rob Waldron, CEO 2008–2024, now Chairman
- Segment and buyer
- K-12 (core strength K-8). School districts and schools buy assessment, supplemental instruction and core curriculum in reading and math; teachers and students use it
- Scale
- i-Ready used by ~14m students (2026, reported), about a third of US K-8 students by company estimate. Revenue "nearly $800m" a year (2024, Boston Globe). ~2,500 employees (2024), up from ~100 in 2008
- Capital raised / valuation / market cap
- No venture capital. Private-equity transactions in 2017 (Berkshire), around 2019–21 (Permira, timing verify) and 2022 (H&F minority). Prices and valuations not disclosed; trade press speculated the 2022 auction valued CA in the multibillion range (unconfirmed)
- Signature moves
- Founding as a print supplements publisher (1969). Waldron turnaround and digital pivot (2008). i-Ready launch (2011). Ferguson/Berkshire deal and gifts to Iowa State and the Boston Foundation (2017). Core curriculum push (Ready Classroom Mathematics, ~2019–20). Pandemic learning-loss data (2020). H&F minority stake (2022). $100m employee stock gift (2023). CEO transition and i-Ready Pro (2025). Misses and controversies: student and parent backlash over screen time and repetitive lessons, criticism of self-funded efficacy research, privacy and advertising lawsuits (2025–26)
