OSAT Chemistry study guide
OSAT Chemistry · Work through your exam, one topic at a time.
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. Topics on this exam: Chemistry content domain (not enumerated in source). The OSAT Chemistry study guide has 1 section and about 398 words.
01Chemistry Content Domain
The OSAT Chemistry content domain samples the full breadth of a secondary chemistry curriculum: atomic structure and periodicity, chemical bonding and intermolecular forces, stoichiometry, gas laws, solutions, kinetics, equilibrium, acid–base chemistry, thermodynamics, electrochemistry, organic/biochemistry basics, and laboratory safety. Expect items that ask you to predict, calculate, and explain-not merely recall definitions. Because the exam does not publish a finer subdomain list, build a connected model rather than memorizing isolated facts. Use the periodic table as a predictive tool: effective nuclear charge increases across a period, atomic radius decreases, ionization energy and electronegativity increase; down a group, radius increases and ionization energy decreases.

- Practice questionsWhich statement correctly describes the arrangement of particles in a solid at the particle level?
- FlashcardsMass number. The sum of protons and neutrons in an atom's nucleus; written as a superscript before the symbol.
- Cheat sheetAtomic structure: Z = protons = electrons in a neutral atom; mass number A = protons + neutrons; isotopes differ only in neutron count and share chemical behavior but differ in mass.
- Key termsmole. The amount of a substance containing 6.022 × 10^23 representative particles, used as the counting unit that links particle-level quantities to measurable laboratory masses.
- Study planBuild a one-page equation sheet covering stoichiometry, gas laws, thermochemistry, and equilibrium, writing each formula from memory before checking a reference.
- Common mistakesThe mole is the natural unit of the calculation, so candidates stop at the mole result, especially when the item asks for mass and the arithmetic already feels finished.
