OSAT Middle Level/Intermediate Mathematics (225)

It is a computer-based test with 80 selected-response questions and 1 constructed-response assignment. You get 4 hours of testing time within a 4 hours and 15 minutes total appointment time; 15 minutes of the appointment covers the CBT tutorial and nondisclosure agreement. An on-screen scientific calculator and a set of definitions and formulas are provided.

The total appointment time is 4 hours and 15 minutes, of which 4 hours is testing time. The remaining 15 minutes is for the computer-based testing tutorial and the nondisclosure agreement. Plan your pacing around the full 4 hours of testing time, and budget part of it for the constructed-response assignment.

The passing score is 240. Your score report shows your result and testing history, and the CEOE site publishes a test and score dates schedule so you know when results are released. Review the score reporting policies before you test so you understand how and when your results arrive.

The test fee is $118. Payment and fee information is published on the CEOE site, so confirm the current fee and accepted payment methods when you register rather than relying on secondhand figures. Registration is completed online through the CEOE website.

Yes. Candidates have the option to take either the Certification Examinations for Oklahoma Educators version or the National Evaluation Series version of this test, and both assess the same critical content areas. Review the policies for each test and consult your educator preparation program and/or the Oklahoma State Department of Education before choosing.

Testing is by appointment year-round, Monday through Saturday, excluding some holidays. The test is offered only at specific test centers in Oklahoma and nationwide, so check seat availability and find a test center before you schedule. Availability varies by site and date.

The test spans both breadth and depth of middle-level mathematics, and the single constructed-response assignment carries real weight, so candidates who only drill multiple-choice items often underprepare for it. The most common failure modes are weak written justification, careless arithmetic without the provided calculator, and running out of time on the final questions.

Start by reviewing the definitions and formulas provided with the test, since those are the tools you will actually have on test day. Then work through the official preparation materials and tutorials, practice selected-response questions under time pressure, and finish by writing full constructed-response answers and comparing them against the scoring guidance.

An on-screen scientific calculator is provided with your test, and definitions and formulas are provided as well. The test includes an assignment that allows you to handwrite and scan your responses; review the hand-draw tutorial and scanning instructions beforehand, since those instructions are also available during your test.

Not necessarily. Tests may include test questions that are being evaluated for future administrations and that do not affect a candidate's score. Treat every question as if it counts, since you cannot tell which items are being field-tested while you are taking the test.
