In response to a relatively new method of measuring student progression, or "value-added" data, Seattle Times investigates the effectivenss of this new metric in Seattle Public Schools. Value-added data measures how much each student progresses in a year by predicting what the student's next standardized test score will be. If the student achieves that score, the data states that the student if progressing at an average rate. If they score higher on the test, the data identifies how effective the school was in helping the student to progress at an above average rate. This investigation revealed that, just because students scored higher on the Washington Assessment of Student Learning (WASL) does not necessarily mean that they learned more.
