Praxis Scores
The Praxis Earth and Space Science test is scored using a scaled scoring method. Here’s how it works:
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. This scaled score will range somewhere between 100 and 200.
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.
