History
CTB was established in 1926 in Los Angeles by Ethel Clark. 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. One year later, she heard from her first customer: the Kansas City school district. In 1960, the company relocated to Monterey, California, where the company headquarters was located until merged into DRC.In 1965, CTB was acquired by McGraw-Hill Education and became CTB/McGraw-Hill.
On June 30, 2015 McGraw-Hill Education announced that Data Recognition Corporation had agreed to acquire "key assets" of the CTB/McGraw-Hill assessment business.
