OST Algebra I study guide
OST Algebra I · Work through your exam, one topic at a time.
The Ohio State Tests (OST) in Algebra I are Ohio's end-of-course assessments in mathematics, administered through the Ohio Department of Education and Workforce's testing program. The exam is intended for Ohio students completing an Algebra I course, and results feed into state accountability reporting and, depending on a student's graduation pathway, into graduation requirements. This independent study page is not affiliated with, endorsed by, or sponsored by the Ohio Department of Education and Workforce; it is a preparation resource, and candidates should always confirm current administrative details with their school counselor or the Department's official testing pages. Because the Department's public pages are periodically reorganized and the specific pages consulted for this profile returned "Page Not Found" notices at retrieval, verified figures for item counts, testing time, scoring, and retake rules are not published here; treat any number you see elsewhere as unverified until the Department confirms it. The OST Algebra I study guide has 4 sections and about 1,246 words.
01Number and Quantity
The Number and Quantity domain on OST Algebra I tests whether you can reason with quantities, units, precision, exponents, radicals, and scientific notation. Items often embed these skills inside multi-step word problems rather than asking isolated arithmetic.
282 words, about 1 min02Algebra
The Algebra domain covers seeing structure in expressions, polynomial arithmetic, creating equations, and reasoning with equations and inequalities. OST items ask you to justify each step, choose efficient methods, and interpret solutions in context.
350 words, about 2 min03Functions
The Functions domain tests function notation, domain and range, rates of change, linear and exponential models, transformations, and interpretation of graphs. Expect items that ask you to compare two functions represented differently-equation, table, graph, or verbal description.
301 words, about 2 min04Statistics and Probability
The Statistics and Probability domain asks you to summarize and interpret data, read two-way tables, analyze scatterplots, and use linear models. OST items emphasize interpretation: what a slope, intercept, association, or conditional frequency means in the given context.
