You can also find related info at the state's department of education, Jorrie. For example, see this 2010 report card for the district, http://apps.sde.state.ok.us/apireports/APIreports2010/72I007.PDF.
With it you can get some sense of how students with IEPs fare in the district, as compared with peers that do not have IEPs. School level report cards, again for 2010, can be found here, http://www.sde.state.ok.us/AcctAssess/APIReportCards_Site/20
Good luck with your research and your move to Skiatook!
