UPDATE!
As of August 31st, 2022, teachers can now reset students' LevelSet scores directly from the new LevelSet scheduler tool. Teachers have 30 days after the administration of the test to reset a student's score and they will only be able to reset the most recent score (i.e. the Pre-test cannot be reset if the Interim was already completed).
To conduct a reset, simply open the LevelSet Scheduler from the left sidebar menu and select the relevant class. Any students that have recently completed the assessment will display a blue, hyperlinked score.
Click the score to reveal a pop-up window where you can view basic testing information & reset the selected student. Once reset, students will be prompted to re-assess the next time they sign in during Supervised Work Time. 
*Please know that you may only re-administer LevelSet once per student per testing occasion. To help ensure the re-administered assessment results in a valid score, please prepare both the student and the testing environment.
LevelSet can be administered up to three times a year (Pre-Test, Interim, and Post-Test) to enhance the validity of students’ Lexile® reading scores and allow for greater precision in measuring reading gains and tracking progress toward College and Career Readiness targets and/or state proficiency targets.
To minimize practice effects for students who are administered the LevelSet multiple times, the LevelSet has been designed to prevent students from responding to the same items from one testing occasion to the next. However, there are instances, particularly when the LevelSet is reset and re-administered too many times, where students may respond to a same set of items that they have previously seen.
The LevelSet contains 11 grade-level versions ranging from Grades 2-12, and each grade-level version is unique in that the items only occur at one grade-level and are not shared across grade-levels. After the very first Pre-Test LevelSet that students ever complete, the grade-level version that they are assigned to is based on their Lexile measure. As such, if a student’s Lexile level increases between LevelSet administrations (i.e., within a school year, or even from one school year to the next), they will be assigned to a different LevelSet with a new set of items.
Within each grade-level, there are three alternative forms of the LevelSet, and each alternative form is unique in that the items only occur on one alternative form and are not shared across alternative forms. The following logic is in place to ensure that students who complete the LevelSet up to three times at the same grade-level within the same or following school year are assigned to different sets of items:
If a student’s Lexile measure remains at the same grade-level for up to 6 administrations of the LevelSet within the same or following school year, the following logic is in place to ensure that the student continues to be assigned to a different set of items on the fourth to sixth administrations. Note that this is accomplished by assigning the next higher grade-level version of the LevelSet:
If a student’s Lexile measure remains at the same grade-level for more than 6 administrations of the LevelSet within the same or following school year, they will then begin to receive items that they have previously seen. Specifically:
In summary, if a student is tested at the same grade-level up to six times within the same or following school year, they will receive a different LevelSet with new items each time. However, for the fourth to sixth time, those items will be from the LevelSet at the next grade-level. If a student is tested at the same grade-level more than six times, they will begin to receive a version of the LevelSet which they have previously been assigned.
