- Multiselect
- Multipart
- Hot text
- Hot spot
- Inline choice
- Drag and drop
- Text entry
- Constructed response

STAAR Test Scores
The STAAR Biology 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, which can reach a maximum of 78 points. At the end of the test, your final raw score will be converted to a scaled score. This scaled score will range somewhere between 1420 and 6750.
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.
Your final score will fall into one of four performance levels:
Retaking the Test
If you didn’t get the score you wanted on your first try, that’s okay! You can take the test again during any testing administration window.
