Education Commission of the States researched Statewide Longitudinal Data Systems policies in all states, the District of Columbia and Puerto Rico to provide this comprehensive resource. Click on the questions below for 50-State Comparisons showing how all states approach specific SLDS policies, or choose to view a specific state’s approach by going to the individual state profiles page.
UPDATED JANUARY 27, 2020 to include a change in Montana.
- Did the state receive a federal SLDS grant? Years of the grant? Funding received?
- Does the state have an SLDS? What is the name of the SLDS?
- How was the SLDS established?
- How are the connections structured?
- Which of the four core agencies (EL, K12, PS, WF) are included?
- Does the SLDS website feature a publicly available data dictionary or data manual?
- All data points for all states
Core Agencies and Statewide Longitudinal Data Systems: Four state agencies are designated as core agencies within any SLDS: early learning, K-12, postsecondary and workforce. For the purposes of this 50-State Comparison, an SLDS is defined as one with formal connections across two or more of these core agencies. States with at least two of these core agencies in their data systems are designated as having established an SLDS. As such, the data systems that meet this definition might not always be those systems associated with the federal SLDS Grant Program.
Centralized vs. Federated Systems: State data systems that collect, retain and maintain data from multiple agencies in a centralized warehouse are designated as centralized systems and state data systems where data from participating agencies were linked either temporarily or on an as-needed basis are federated systems.
Systems in Development: If a state’s SLDS is still in development, the state is not designated as having established an SLDS. However, Education Commission of the States made its best efforts to identify such states and designate them as being in the process of establishing an SLDS.
- All 50 states, the District of Columbia and Puerto Rico have the ability to connect data between systems.
- Forty-one states and the District of Columbia currently connect data between at least two of the four core systems (early learning, K-12, postsecondary and workforce).
- Sixteen states and the District of Columbia have a full P20W system that captures data across all four core agencies, from early learning through the workforce.
- Twenty-nine states and the District of Columbia have a centralized system, while 12 states have a federated system.
- Of the 41 states and the District of Columbia that connect data:
- Sixteen states and the District of Columbia created their system through statute or legislation.
- Twenty states created their system primarily through a federal grant.
- Three states created their system through memorandums of understanding between agencies.
- Two states created their system through executive order.
