The Integral NVC Toolkit is an open-source model, divided into 4 levels: Level 1, Level 2, Level 3 and Level 4. The draft version of Level 1 is available here (version 0.2). This is very much a work in progress – your feedback is needed to help co-create and evolve this work into its full potential. You will find a button to give feedback on the bottom of each page – and all feedback is welcome!
