Nurse Aide Program: Registry Statistics
We track the number of active nurse aides on the Wisconsin Nurse Aide Registry. Wisconsin TestMaster Universe houses the registry. The table below shows active certifications at the time we ran the report at the end of each month.
Some nurse aides may lapse on the registry. They are allowed to continue working in some health care settings and renew late. Late renewals cause the monthly numbers to change. We update all monthly numbers at the end of each calendar year to reflect the most recent totals.
