How to Register
To get started with the registration process, you’ll need to create a MyPSC account on the GaPSC website. You should receive a Georgia Certification ID (GA CERT ID) during this process, which you’ll use for identification throughout the registration and testing process.
The next step is to create an ETS GACE testing account on the ETS website. This account will allow you to register for the exam and pay the testing fee(s).
How the Exam is Scored
The GACE Science test is scored using a scaled scoring method. Here’s how it works:
Scaled Scoring
For every question you answer correctly, you get one point added to your raw score. At the end of the test, your final raw score will be converted to a scaled score.
The reason your raw score is converted to a scaled score is because everyone that takes the test is given a slightly different set of questions. Since everyone has a different arrangement of questions, and because some questions are harder than others, converting your raw score to a scaled score ensures a more even playing field.
Retaking the Exam
If you don’t get the score you want on your first try, that’s okay! You can take the exam again after a mandatory 30-day waiting period.
