He congratulated them on above average test scores.
The Missouri Assessment Program test and the End-of-Course tests are based on the Missouri state standards, which define what students should be learning each year and in each subject.
"I think it shows that we've got a lot of good people from leadership down to our students that are working hard to try to be the best that they can be," said Chillicothe High School principal Brian Sherrow.
Governor Nixon also touted his budget proposal that would provide $278 million for students in kindergarten through 12th grade classrooms over the next two years.
The Chillicothe School District would get nearly $680 thousand dollars under the plan.
Nixon said the plan would help ensure that all students in the Missouri have an education that's above average.
His plan includes lowering tuition, offering more scholarships, and making more college courses available for high school seniors.
"Putting additional resources this year to help keep down debt for students who move on so they'll instead get opportunities instead of debt," added Nixon.
The governor says in order to create global competition and a better economy, the bar needs to be raised on public education.
"The best economic development tool there is is education and fully funding the foundation formula is an important aspect of that," said Nixon.
He said with these incentives, students would be able to compete against students worldwide for jobs.
"Bottom line is, they can go anywhere and we need to keep them here and one of the ways to do that with is best and the brightest is just to make sure they stay here," stated Nixon.
Chillicothe is leading the way by changing their curriculum to meet those standards by following Nixon's "Good Schools, Good Jobs" program.
"Take our current standards to GLE's and CLE's and get to the Missouri learning standards to match up with the common core," added Sherrow.
Nixon's visit to Chillicothe was the first for the school as he travels the state to gather support for his proposed budget.
