ExploreAbout this exam
Chemistry (104) is the current Certification Examinations for Oklahoma Educators (CEOE) chemistry test, listed on the CEOE test menu alongside the other Oklahoma educator certification assessments. It replaced the retired Chemistry (004) version; the program page for (004) states plainly that the older test has retired and that the new Chemistry (104) test has replaced it and is now available. Candidates typically take it to demonstrate subject-matter competence in chemistry for an Oklahoma teaching credential, and registration for the redeveloped test opened on 8/29/23, with CRI pilot testing announced on 4/24/24 and pilot sessions available starting 5/15/24.
Because the public test page available for this exam is the retired (004) page, the most reliable published details come from that page: 80 selected-response questions plus 1 constructed-response assignment, a 4-hour testing time inside a 4-hour-and-15-minute total appointment (15 minutes for the CBT tutorial and nondisclosure agreement), a passing score of 240, a $118 test fee, and an on-screen scientific calculator plus a provided periodic table. That page also notes the assignment allows handwritten, scanned responses, so practice handwriting under time pressure.
Preparation should combine content review across the chemistry subfields you will teach with timed practice on both item types. Use the CEOE preparation materials, tutorials, and practice tests referenced on the program site, and rehearse explaining chemical reasoning in writing for the constructed-response assignment.
What you'll study
About OSAT Chemistry preparation
Which test should I register for, Chemistry (004) or Chemistry (104)?
Register for Chemistry (104). The CEOE page for Chemistry (004) states that the (004) test has retired and that the new Chemistry (104) test has replaced it and is now available. The (004) page remains online, so candidates searching for it can land on outdated information; the test menu on the CEOE home site lists Chemistry (104).
What is the test format?
According to the published Chemistry test page, the exam is computer-based and contains 80 selected-response questions and 1 constructed-response assignment. The constructed-response assignment permits handwritten responses that you scan, so review the hand-draw tutorial and scanning instructions before test day; those instructions are also available during the test.
How long is the appointment, and how much of it is actual testing time?
The published page lists 4 hours and 15 minutes of total appointment time, which includes 15 minutes for the CBT tutorial and nondisclosure agreement, leaving 4 hours of testing time. Plan your pacing around that 4-hour block rather than the full appointment window, since the tutorial and agreement consume the remainder.
What score do I need to pass?
The passing score listed for the Chemistry test is 240. Score reports are released according to the test and score dates schedule posted on the CEOE site, so check that schedule for your administration rather than assuming a fixed turnaround. The page does not state a validity period for scores.
How much does the test cost?
The test fee shown on the Chemistry test page is $118. Fee and payment information is linked from that page, and program announcements have in the past described limited-time refund offers for registration and practice test fees, so confirm current pricing and any active offers when you register rather than relying on older announcements.
What reference materials are provided during the test?
An on-screen scientific calculator is provided with the test, and a periodic table is also provided. You can review the periodic table on the CEOE site before test day. Because the calculator is on screen, practice with a comparable on-screen tool so that calculator use does not slow you down during the selected-response section.
When and where can I take the test?
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, and the site directs candidates to check seat availability and find a test center. Online proctoring was announced as available for select tests, so verify whether Chemistry is among them.
How should I split study time between the multiple-choice questions and the constructed-response assignment?
Do not leave the constructed-response assignment until the final week. The 80 selected-response questions reward broad content coverage, but the single written assignment rewards organized chemical explanation under time pressure. Practice writing full responses by hand, then scanning them, and time yourself so the writing task does not eat the selected-response budget.
What are common reasons candidates fall short?
Two predictable failure modes stand out given this format: neglecting the constructed-response assignment until late in preparation, and losing time to unfamiliar tools such as the on-screen calculator or the handwritten-response scanning process. A third is studying only narrow content. Build a study plan that covers the full chemistry scope and rehearse the logistics before test day.
Are practice tests available?
The CEOE program site advertises preparation materials for every test, including sample questions and interactive practice tests, and has announced free practice tests with registration for select tests. Check the preparation materials for Chemistry (104) directly, since availability and any free-with-registration offers vary by test and change over time.
