Using an ice flow model to make inferences of real world systems requires a highlevel of confidence in the model. Verification and validation (V&V) is a set oftechniques that are used to quantify confidence and build credibility. We are developing LIVVkit (Land Ice Verification and Validation toolkit), acomprehensive V&V toolkit for ice sheet models, to help scientists make robustinferences of real world systems with their models.  LIVVkit is written inpython, due to its wide usage throughout the scientific community and should beeasily accessible to a large number of users. The toolkit provides resources fordata assimilation, verification testing, validation testing, and performanceevaluations. A website is created automatically which presents the testingresults in a comprehensive and user-friendly way.  LIVVkit allows scientists anddevelopers to implement reusable validation tests of model applications andbuild confidence in their ice flow model. Currently, we are working withscientific users and developers of the Community Ice Sheet Model (CISM) for thedevelopment of LIVVkit, but LIVVkit is designed to be extensible to other iceflow models.
