Growth Scale Values
Scales that accurately measure change over time
Growth Scale Values (GSVs) measure change relative to the examinee rather than the general population. They are a linear translation of the Rasch Ability Scale, are more accurate and sensitive to performance than a raw score and can be used for multi-point test items. Many of our own assessments have the capability to develop GSVs.
