Three Arizona schools have been ranked as the best in the country.
"We work together with the teachers and faculty to make this a really unique experience and unique education so it's definitely a matter of pride for us," said Lauren Girouard, a high school senior at Gilbert Classical Academy.
School principal Jodie Dean said the school prides itself on student achievement.
Instead of the state required 22 graduating credits, Dean said students at GCA must have 28 credits to graduate.
Students are also required to start taking college level classes in the 10th grade.
"There's sweat, there's tears, there's absolute pain sometimes with all the requirements and the testing and it's nice to be able to have them walk across the stage knowing they left it all here," said Dean.
Dean said the 37 graduates this year have collectively earned nearly $5 million in scholarship offers.
