Justify test validity

The Definition of Test Validity is, does the test measure what one says it measures?

So the question is, does the Sit and Reach test measure hamstring flexibility?
This tests only measures the flexibility of the lower back and hamstrings, and is a proven to be a valid measure for the hamstrings, if performed correctly.  The fact that this test also tests each individual leg makes it more valid then the traditional sit and reach which tests both legs at the same time.
