Over 160 Minnesotan principals and assistant principals have signed a pledge to 'de-center whiteness' in education. 

The group of 162 branded themselves the 'Good Trouble Principals' - citing a quote from the late Georgia congressman and civil rights icon John Lewis.

In the pledge they said they are 'a loose collection of local principals bound together by a commitment to changing our nation's future by engaging in better, more equitable education practices'.

The coalition vowed to '[dismantle] the practices that reinforce white academic superiority' - including standardized testing and what they called an 'Americanized version of the caste system in our schools'. 

'The fight for educational equality rages on and so does our counter,' reads the pledge. 

'We will not be moved. We write to say it is our role as school principals to be the faces and names of this fight; to be in the forefront and not the shadows.'

'We will not pledge loyalty to an institution over loyalty to the purity of children.'

The group's name was inspired by the following John Lewis quote: 'Do not get lost in a sea of despair. Be hopeful, be optimistic. Our struggle is not the struggle of a day, a week, a month, or a year, it is the struggle of a lifetime. Never, ever be afraid to make some noise and get in good trouble, necessary trouble.'

Mauri Melander Friestleben, one of the principals who signed the document, told Fox News that the group's goals include 'increasing varieties of student and school evaluations that go beyond... the standardized testing process'.
