  • What Is The IDW?

    CoSer: 602.094 

    The Nassau BOCES Instructional Data Warehouse (IDW) is a repository for student data collected from multiple sources and organized for analysis and reporting. Those who take advantage of the IDW can access data on multiple criteria without affecting the original source data and enrich district professional learning and instruction.

    The data available for district analysis expands as it accumulates from year to year. The IDW provides a wide variety of reports for all New York State assessments to be used for curriculum analysis. It also yields reports regarding diploma type and college tracking of graduates. Data can be downloaded for further disaggregation, and all reports can be saved and/or printed as needed.
