What is a 'filter question'?
A 'filter question' is a question that is asked in order to determine if a student meets the criteria for subsequent follow up questions. Students will be asked different questions depending on the answer they provide to the filter question.
Filtering is applied to the following measures:

For example…
Student A (Figure 1) and B (Figure 2) both received Question 2. Question 2 is a 'filter question.' If a student responds 'yes,' the next question they will receive is Question 3. If a student responds 'no,' the next question they will receive is Question 4.
| Figure 1 – In the example, Student A responded 'no,' so they were given Question 4, while never seeing Question 3. |
| Figure 2 – Student B responded 'yes,' so they were given Question 3. It is important to note that Student B will still receive Question 4, but only after they receive Question 3. |
What is 'rotation'?
Some questions in the survey are rotated. For example, secondary students receive questions from a bank of rotated questions based on the subjects they indicate that they are currently taking (e.g., Math; Science; Language Arts).
The following measures are impacted by rotation:

Why do we use rotation?
We use rotation in the survey in order to reduce the number of items that a student receives. This ensures that students have enough time to complete the survey and ensures students are not overwhelmed with too many questions.
Because of filtering and rotation, the questions each student will see when participating in the survey will differ slightly from what is displayed in View Survey Questions. View Survey Questions lists all of the possible questions that a student could receive.
