Wisconsin Student Number Locator System (WSLS)

WSLS is no longer in use. We have transitioned to the WISEid application.

WSLS Web Application

The WSLS is used (1) to assign new Wisconsin Student Numbers (WSNs) to students entering Wisconsin Public Schools, (2) to help ensure that the WSNs stay with students as they move from school to school and district to district, (3) to update WSLS data such as when students exit a school or when data used for matching change (e.g. legal name, guardian), and (4) to correct errors in WSLS birthdates, spellings, etc. The WSNs and certain other WSLS data will be used as a starting point for Wisconsin School Performance Report, Fall Enrollment Report, Discipline, Coursework Completion, and ESEA Report Card purposes

WSLS AVAILABILITY AND SUPPORT: Phone and email support of WSLS will be available between 8:00 am - 4:30 pm Monday-Friday. You can continue to use the WSLS at other times of day, including weekends (24x7), but if you have difficulty or if there is a system outage, then you might want to try again between 8:00 am and 4:30 pm M-F. Occasionally, there may be short outages (less than 15 minutes) over the noon hour to address emergency situations. We will try to keep noon hour outages to a minimum.

For New WSLS Users

You must be individually authorized to use the WSLS. Having a Wisconsin User ID (a WAMS ID) is necessary but does not in itself provide access to the WSLS Web application. For security and privacy reasons, access must be specifically authorized by your District Administrator (Superintendent) on behalf of your school board or by the Superintendent's appointed WSLS/ISES Administrator.

For further information about gaining access, see the Delegated Authority Web Application.
