Validation Documentation
Evidence of validity is important to a district for a number of reasons. Primary among these is that statistical validation documentation is the strongest evidence that a measure will help the district select the right people. Additionally, validation documentation is necessary if regulatory or legal entities review a district’s hiring practices.
“Validation” can take a number of forms, but the strongest form involves developing multiple sets of data that, together, provide a pattern of consistent support for the use of a test. Polaris Educational Systems utilizes proprietary job analytic techniques to supply one part of that pattern. Its reliance on the use of proven testing approaches provides a second source of support.
In addition, Polaris conducts statistical validation studies for all of its measures to verify the validity of the instruments in the environments in which they will be used. To see details on the results of typical validation studies, please contact us.
In short, the Polaris approach ensures that the system implemented in a district predicts performance on the targeted jobs. The result is that districts do not need to “reinvent the wheel” by conducting their own validation study. For those who feel a district-specific validation study is necessary, our proprietary tools and methods ensure that the process is neither costly nor burdensome.
