What is Roster Locking?

Educators can lock or unlock Rosters depending on whether they want to prioritize data quality or convenience. Rosters are initially unlocked

  • With a Locked Roster, a student can only access the survey if their Roster ID has already been added to the Class Roster. This ensures a student is identified correctly each time they submit a survey, but educators must add students manually before they can take the survey. 

  • With an Unlocked Roster, students add themselves to the Roster the first time they access the survey for a Class. This means educators don’t need to set up their Class Roster in advance, but unlocked rosters can reduce data quality, for example:

    • If a student accidentally uses different IDs to access the survey (e.g., they mistype their email or they use an email once and a student ID a different time), that student will be treated as multiple students. This will skew data and make it harder to detect meaningful changes.

    • Until all students are added to a Roster, participation percentages may appear higher.

If using unlocked Rosters, ensure students use a consistent Roster ID to access the survey, e.g., only their student ID or school email. Reinforce this by creating a Roster ID Rule (see below).

Roster Tips

  • Create a Roster ID Rule (like “all Roster IDs must end with”) to make sure students use the appropriate type of Roster ID. 

  • Lock Rosters once your Roster has stabilized, e.g., after your schedule adjustment period or add/drop deadline. This will reduce the likelihood that students accidentally use the wrong Roster ID. 

  • Review Rosters and adjust them as needed. For example, you may remove students who are no longer enrolled, ensure students used the correct Roster ID, and/or correct any typos in Roster IDs. 

How do I lock/unlock a Roster(s)?

Community Leads or Class Leads can lock/unlock Rosters.

  • From the Classes tab, select the Class you would like to edit by clicking the box next to the Class name

  • To lock the Roster(s), toggle the Locked button from an X to ✓. The lock icon next to the Class name will appear locked
