You must get buy-in from principals even if you have conducted research at the school previously. “This third year [that
we’ve done the research], we didn’t market to principals well enough. We thought maybe that they would have been more on
board the third year. I think the big lesson is that every year you do research, you’ve got to treat it like it’s the first year, and
really sell it to the people who control whether or not your research is going to be successful. For example, just because you
gave incentives the first year, you shouldn’t think that incentives won’t be necessary the second year. You can’t let up on the
marketing aspect of your research. You’ve got to constantly assume that people aren’t necessarily on board.”
