Gemini Field Tests

The Gemini project was started in 2009 to redesign the survey in an effort to address measurement error. In July 2013, a redesign plan was approved, followed by the creation of a roadmap to further develop and test the redesign plan leading to its implementation. Part of this testing involves several planned field tests. Links to information and materials on each of the Gemini related field tests can be found on this page.
