OAE Mathematics case studies
OAE Mathematics · Put your knowledge to work in context.
Mathematics (027) is one of the Content Knowledge assessments in the Ohio Assessments for Educators program, the testing system used for educator licensure in Ohio. The Ohio Assessments for Educators site lists it simply as "027 Mathematics" among the content-area tests, and the Department of Education and Workforce notes that testing requirements depend on licensure type, so the first step is confirming with the state which assessment your license pathway requires rather than assuming 027 is the right one. The OAE Mathematics case studies are 5 cases and about 3,089 words.
