DRC/CTB (CTB), a division of Data Recognition Corporation (DRC), is a publisher of educational assessment for the early learner, K–12, and adult basic education markets.[1] CTB has published many assessments including California Achievement Tests (CAT), Tests of Basic Experiences (TOBE), and TerraNova.[2]

History

CTB was established in 1926 in Los Angeles by Ethel Clark.[3] Clark's husband Willis had developed the Los Angeles Diagnostic Tests in the Fundamentals of Arithmetic, which she bought the rights to sell. She sent out 25 cent postcards advertising the availability of the test to various districts around the country.[4] One year later, she heard from her first customer: the Kansas City school district.[5] In 1960, the company relocated to Monterey, California, where the company headquarters are currently located.[6][7] In 1965, CTB was acquired by McGraw-Hill Education and became CTB/McGraw-Hill.[2]

On June 30, 2015 McGraw-Hill Education announced that Data Recognition Corporation (DRC) had agreed to acquire "key assets" of the CTB/McGraw-Hill assessment business.[8]

Today

CTB serves more than 18 million students in all 50 states and 49 countries.[9] CTB's current president is Ellen Haley.[10] In 2002, CTB reportedly had a 40 percent share of the test design market, ranking second of the four major companies in the industry.[11] In 2011 CTB acquired Bookette, a privately held software company. In June 2011, CTB celebrated its 85th anniversary.[12]
