The Cross Data Project is a sustained, on-going strand of professional development designed to empower educators to think critically about student performance data, construct tiered lessons to meet learner needs, and engage stakeholders in transforming conversations using data. The session is designed for teachers and administrators who are interested in local efforts to make data meaningful to students, create user-friendly, customized technology tools, and frame conversations around data to transform practice. http://www.nwea.org/membersseminar/2008/agenda.asp
