The Illinois Longitudinal Data System (ILDS) is Illinois’s public education state longitudinal data system (SLDS) governed by the LDS Governing Board, an intergovernmental committee comprised of the members from each of the state agencies that contribute to the ILDS and an appointee from the Office of the Governor. The ILDS, created for the purpose of collecting and analyzing Illinois public education data at the individual, course, institution, and system levels, aggregates data records from the breadth of the Illinois public education systems. The combined data collection systems are part a nation-wide effort to record granular public education detail over time in order to document the entirety of students’ education experience. This information is intended to be available for analysis and public policy consideration for the purpose of producing improvements in student learning at elementary, secondary, post-secondary, and higher education levels, and to optimize labor market outcomes, individually and generally.
Illinois is one of the 47 states having received public funding to create a state longitudinal data system (SLDS). Despite state-to-state differences, each SLDS shares a common purpose of supporting research and analysis with the intent of informing individual, household, and public policy decisions based on standardized criteria.
 The Illinois Longitudinal Data System enables state agencies to link early childhood, education, and workforce data to answer questions critical to understanding Illinois’s future education workforce needs https://www.illinoisworknet.com/ILDS/Pages/default.aspx
 State longitudinal data systems are intended to enhance the ability of states to efficiently and accurately manage, analyze, and use education data https://nces.ed.gov/programs/slds/about_SLDS.asp

This review assesses the overall quality of the ILDS as an SLDS by considering the nature of the organization maintaining the data system, those agencies and institutions providing inputs to the data system, and to which agencies and institutions the data systems’ outputs are available. The assessment also considers the data system’s funding mechanisms, internal and external researcher data accessibility, the quality of the data system’s public user interface (dashboard), and the data system’s current Data Quality Campaign (DQC) ranking. This report considers each of these criteria pertaining to ILES and provides contact information to the departments and individuals who maintain and manage the SLDS.
 The Data Quality Campaign is a national, nonprofit organization leading the effort to bring every part of the education community together to empower educators, parents, and policymakers with quality information to make decisions that ensure students excel http://dataqualitycampaign.org/

Governance and Maintenance
The ILDS is governed by the ILDS Governing Board, a committee comprised of the representatives from the stage agencies whose data systems provide data records to the ILDS and an appointee from the Office of the Governor. The members of the board include:
- Illinois Board of Higher Education
- Illinois Community College Board
- Illinois Department of Commerce and Economic Opportunity
- Illinois Department of Employment Security
- Illinois Department of Human Services
- Illinois State Board of Education
- Illinois Student Assistance Commission
- Office of the Governor
The ILDS Governing Board works to establish an internal set of tools, systems and processes for the ILDS that can be shared across state agencies to ensure data interoperability between each agencies’ data system. The ultimate goal of the board is to support the analysis and understanding of lifelong education and workforce policies and programs within the state of Illinois and allow the state education and workforce policy makers to utilize research based decision making practices. The board addresses issues that are shared by each of the participating state agencies, such as how data will be accessed by internal and external agents, how data records will be secured and how to ensure that the participating state agencies share data in accordance with established procedures and rules. The board is mandated to address these issues in ways that ensure robust protections for individual privacy and compliance with all pertinent state and federal laws. The board also works with external advisors working within the education and workforce fields to make certain that the ILDS is inclusive to outside perspectives and audiences.
An important role of the board is to annually establish a plan for major ILDS-related activities for the upcoming 18 months. This plan guides the agencies in determining ILDS priorities and projects.
 The Illinois Board of Higher Education was created in 1961 to plan and coordinate Illinois’s system of colleges and universities http://www.ibhe.org/aboutBHE/default.htm

The ILDS is both a governance system to establish and manage data sharing priorities and projects across the 7 agencies, as well as a technical approach to identity resolution across the 7 agencies. For the purpose of addressing identity resolution, the ILDS receives demographic data from each of the state agencies that comprise the ILDS Governing Board. The data records from the various state agencies’ data systems are compiled in the Centralized Demographic Dataset (CDD) and managed by the Centralized Demographic Dataset Administrator (CDDA). The CDDA maintains a data warehouse which contains the CDD and the Master Client Index (MCI), a data system which performs record linkage between data records within the CDD. The MCI provides data interoperability between the state agencies’ data systems that provide records to the CDD, improving the quality of data and matching rates within the CDD. The CDDA is tasked to provide the following services that generally relate to the identity resolution system:
- Develop and maintain a Batch File Exchange process to achieve a standardized exchange protocol for the data records compiled within the ILDS
- Develop and provide maintenance for the Master Client Index that identifies and tracks each state agencies unique identifier from their respective data systems
- Provide identity resolution services to identify and reconcile records with the MCI
- Provide a confidence rating service to determine matches and non-matches between data records from different state agencies’ data systems
Northern Illinois University (NIU) was officially designated to be the CDDA for the ILDS. NIU was chosen through a competitive RFP process because of its ability to provide supporting services to the ILDS in addition to the previously mentioned services. NIU developed a CDDA dashboard with a user-friendly interface which enables authorized LDS agency staff members to easily monitor and manage CDD data activities. NIU also provides demographic data standardization guidance and technical support to the LDS agencies. It establishes common data structures and data definitions that LDS agencies should adhere to and follow within their data systems to reduce potential data errors and inconsistencies between different system’s data records.
The data records provided by the LDS agencies allow the ILDS to link early childhood, education and workforce data through the CDD and the MCI. The reports provided by these linkages enable to the ILDS Governing Board to use research driven analysis to answer questions about Illinois’s current and future education and workforce needs. Some examples of projects that have been undertaken through the ILDS include creating the first unduplicated count of children receiving publicly funded early childhood PreK and childcare services, identifying and reporting on high school students transitioning to community colleges in remedial education courses, and analyzing employment outcomes for career pathway participants. The specific data records provided by the LDS agencies to the ILDS to answer these questions are listed as follows:
- Illinois Board of Higher Education – Higher-education data records
- Illinois Community College Board – Post-secondary data records
- Illinois Department of Commerce and Economic Opportunity – Workforce training data records
- Illinois Department of Employment Security – Employment data records
- Illinois Department of Human Services – Early childhood data records
- Illinois State Board of Education – Early Childhood and K-12 data records
- Illinois Student Assistance Commission – Financial aid data records

The ILDS Governing Board has created a common data sharing agreement template that can be used for projects involving multiple ILDS agencies and a third-party organization. In addition, the ILDS agencies have begun the process of aligning their data request form questionnaires into a common form. These agencies are expected to finalize and publicize a common interagency data request form questionnaire in early 2017. These developments will significantly decrease the difficulties and inefficiencies of the data sharing process with third-party organizations. Access to specific ILDS agency’s data will still require consent from that ILDS agency’s separate processes and protocols but these processes and protocols should differ little from the common data sharing agreement template.

The Illinois General Assembly enacted the Public Act 096-0107 into state law as the P-20 Longitudinal Education Data System Act, effective July 30, 2009. The Senate and House passed the act, and the Governor signed it, so that the state education agencies and other ILDS partners could follow students and their performance throughout their education experience and their subsequent labor market experiences. The P-20 Longitudinal Education Data System Act specifically outlines the purpose of the ILDS and designates each relevant state agency’s role in developing and expanding the ILDS. The act sets fixed deadlines for the ILDS’s progress and milestones starting from the enactment of the act to 2013. Importantly, it established clear authority for state education agencies to collect necessary information fort the ILDS, including providing new authority to the Illinois Board of Higher Education to collect student unit records from public and private post-secondary institutions. It also establishes that the ILDS will adhere to all state and federal laws related to education systems, student privacy requirements and appropriation of federally granted funds.

The Data Quality Campaign (DQC) is a nonprofit, nonpartisan national advocacy organization that evaluates each state’s longitudinal data system to determine how effectively each state uses their data system for education improvement purposes. The DQC’s annual survey, Data for Action (DFA), measures each state’s progress towards implementing the 10 Essential Elements of Statewide Longitudinal Data Systems and the Ten State Actions to Ensure Effective Data Use, a set of elements and policy actions proposed to produce quality data systems and increase student achievement within in each state.
Illinois has currently met each of the 10 essential elements:
- Element 1 – Statewide student identifier
- Element 2 – Student-level enrollment data
- Element 3 – Student-level test data
- Element 4 – Information on untested students
- Element 5 – Statewide teacher identifier with a teacher-student match
- Element 6 – Student-level course completion data
- Element 7 – Student-level SAT, ACT, and Advanced Placement exam data
- Element 8 – Student-level graduation and dropout data
- Element 9 – Ability to match student-level P-12 and higher education data
- Element 10 – State data audit system
Illinois has currently met 5 of the 10 state actions:
- State Action 2 – Create stable, sustainable support for longitudinal data systems
- State Action 3 – Develop governance structures for longitudinal data systems
- State Action 4 – Build state data repositories
- State Action 7 – Create reports with longitudinal statistics to guide system-level change
- State Action 8 – Develop a purposeful research agenda
Data Quality Campaign score: 5/10
It should be noted that the Data Quality Campaign assessed each state’s progress towards completing the state actions in 2014. At this time, Illinois had failed to meet the following state actions:
- State Action 1 – Link state K-12 data systems with early learning, postsecondary, workforce, and other critical state agency data systems
- State Action 5 – Provide timely, role-based access to data
- State Action 6 – Create progress reports with student-level data for educators, students, and parents
- State Action 9 – Implement policies and promote practices to build educators’ capacity to use data
- State Action 10 – Promote strategies to raise awareness of available data
In 2016, Illinois has reported to have met State Action 1 and is in the process of meeting State Actions 5,6,9, and 10.
 DQC’s annual survey, Data for Action (DFA), is a powerful tool to inform efforts in education to better use data in decision making. It is a series of analyses that highlight state progress and key priorities to promote the effective use of longitudinal data to improve student achievement
 DQC’s 10 Essential Elements of Statewide Longitudinal Data Systems and 10 State Actions to Ensure Effective Data Use provide a roadmap for state policymakers to create a culture of effective data use in which quality data are not only collected but also used to increase student achievement
