The Wisconsin Information System for Education (WISE) system replaced the existing Wisconsin Student Numbering System at the end of the 2015-2016 school year. The system is comprised of a number of tools, but only two of them are important for Gradelink users: WISEid and WISEdata.

WISEid assigns a unique, permanent Identifier Number (ID) to individuals that are part of the Wisconsin education system, including both staff and students.

WISEdata allows school districts, charter schools, and private schools participating in a parental choice program to submit data to the DPI from the SIS of their choice.
