    of the reliability or validity of these tests. Based on my very small sample size as a parent, the scores my child has received have been pretty bouncy from year to year. They don't seem to be very reflective of much aside from maybe how he was feeling that day or how much effort he wanted to put into the test. Some years he does great, other years not so much, and I don't think it's that his academic progress really changed a lot from one year to another.

    Statistics and data analysis are a big part of my work and I am a believer in statistical modeling. I actually think the value-added models are really nicely done from a statistical point of view. But if the data that are going into them are not reliable it is really hard to draw many conclusions based on the results of the models.
