IDEA Data Quality: Outlier Analyses Tools

IDC designed these two technical assistance products to be used by state personnel responsible for IDEA 618 and/or 616 data. The products include a step-by-step guide on completing an outlier analysis, with a brief introduction on the principles of outlier analysis, and a tool state staff can use to conduct outlier analyses with their local data. IDEA Part B state staff working with LEAs also can use both products to analyze their local data. Any state staff with the ability to examine and analyze IDEA 618 and/or 616 data also would benefit from these technical assistance products.
