This work is significant for two reasons. First, and most obviously, we are beginning to answer the question for which this project was designed. And this work illustrates that AMSP is beginning to generate positive and significant effects on student learning. We caution that the work is ongoing and continues to be updated and refined and the magnitudes and significance levels of our estimated coefficients may change as we go forward. There are additional data that we wish to collect. But independently of our specific results, this study makes an important contribution in that we have established a method for evaluating the effects of AMSP in Kentucky. We present a scientifically sound method for estimating the effects of AMSP on student learning independently of other factors that also affect learning.
