After conducting a linear regression analysis of Interpretive Reading (Pre-test) scores (Table 12), the coefficient or Y-intercept associated with the pre-test scores, (0.696985136) is zero, and reveals that the variability in student outcomes cannot be explained by the regression of student gains and losses on pre-test scores.

You should start by plotting the data. A look at a scatterplot could be very revealing.
