RHINELANDER - A Rhinelander high school student walked into school Wednesday not knowing that during the school day he would win a car.
Throughout the school year, students are rewarded for doing good deeds with green cards.
At the end of the year, thousands of green cards are put into a drawing for prizes from departments in the school and local businesses.
The grand prize is a car from Rhinelander GM.
Students got to choose a rubber duck out of a pool. Each duck had either a key or a number on the bottom.
Students whose duck did not have a key on it got a basket full of gift cards, treats, and a variety of other things.
Senior Jaxon Klitzka was one of the lucky seven students who got to test to see if his key would start the car.
"I was thinking analytics the whole time, and I'm up there [thinking] one in seven, 16 percent, somewhere around there. One went down and I'm like, it's a one in six shot…this is getting insane," said Klitzka.
Klitzka's key was the one that started the car, which he will soon get to drive home.
The green cards are part of the school's Positive Behavior Interventions and Supports (PBIS) program.
"It's a program that helps us systematically look at student behavior and makes some decisions about what we want to do to help them proactively behave the way that we expect them to be able to behave when they get out of the high school," said RHS German teacher Steve Geiger.
Next year students will also earn green cards for things like attendance record, behavior record, and other data driven aspects.
