Illinois Longitudinal Data System

The Illinois Longitudinal Data System (ILDS) enables state agencies to link early childhood, education, and workforce data to answer questions in areas both important to Illinoisans and critical to understanding the state's future education and workforce needs.

The focus of the ILDS is on the end user, developing a system for reporting in areas that are important to Illinois parents, students, teachers, administrators, and decision-makers.

ILDS is structured to answer some key questions that are crucial to understanding the education and employment outcomes of Illinois learners and citizens.  Some examples of key questions include:

    • How many Illinois children are served by early childhood programs, and what is the impact of these programs on later learning?

    • Are high school graduates prepared to succeed in community colleges and four-year universities?

    • What are the employment outcomes for college graduates and completers of various workforce training programs?
