Cambium Assessment brings 70 years of experience in aptitude and proficiency testing, including more than 40 years in K-12 educational assessments.
We deliver the core grades 3–8 English language arts (ELA) and mathematics testing in 20 states and territories, serving 38% of these students nationwide. In addition, we deliver science and social studies tests to many of these states. In 2017–2018, we administered more than 57 million tests online and 60 million tests in 2018–2019. About 80% of these tests were computer adaptive tests, which means half a billion online transactions were dynamically generated and transported through our networks at the districts and schools.
Our performance continues to be unparalleled in the assessment industry. We deliver our tests with superior system architecture but with technology already in schools. We know how important it is to direct resources into technology that ensures smooth testing administrations, even with millions of test takers.
We have 70 years of experience designing, developing, and implementing large scale tests across the country. Our test developers blend subject matter expertise with pedagogy and a precise technical understanding of how to craft items that accurately measure student proficiency.
