The Madison School District will ask for proof of age when registering students who live with people other than their parents or guardians or those who are 18 years or older and are enrolling themselves for school.
The district disclosed the new procedure -- which goes into effect next month for the 2010-11 school year -- in a statement to the State Journal dated July 23 and received Monday.
The announcement comes three months after the revelation that a 21-year-old gang member charged in a fatal April shooting had enrolled in Madison's West High School and later transferred to Middleton High School under a fake name and age.
Ivan Mateo-Lozenzo, 21, was enrolled at Middleton High School as 18-year-old junior Arain Gutierrez at the time of the shooting. Middleton officials have said Mateo-Lozenzo, who police have identified as an illegal immigrant from Veracruz, Mexico, had transferred from Madison's West High School.
