Test Day
You should arrive at the testing center 30 minutes before your scheduled appointment to allow enough time for the check-in process. Once you arrive, you will be asked to sign in and present one form of valid, government-issued photo ID.
After the check-in process, you will be asked to leave all personal items (phone, keys, wallet, etc.) in a locker outside the testing area.
Once you enter the testing room, you will be asked to sign an NDA, and you will be given a brief tutorial on the computer-adaptive testing system. Once the tutorial is complete, the exam will begin.
How the Exam is Scored
The TExES Chemistry 7-12 exam is computer-adaptive. Here’s a look at how it works:
The first question is judged to be of medium difficulty, and depending on your performance, the next question may be easier or harder. If you do well on the first question, the second question will be harder; conversely, if you do poorly on the first question, the second question will be easy.
The questions on this exam are rated on a scale of 100-300. The higher a question is rated, the harder the question is (e.g., a question marked as 250 will be more difficult than a question marked 150).
To pass the exam, your final question must be on or above the 240 mark. If your final question is below this mark, you will not pass the exam, even if you have answered some questions above the 240 mark at some point during the exam. This is because the computer has rated the difficulty of your final question based on how you answered the previous questions.
