At the Michigan Education Data Center, we know your goal as a researcher is to crunch the numbers and offer insights that will improve lives. We strive to support researchers throughout the life of their research project. Below are just some of the ways we strive to serve.
Individual student records within educational datasets maintained by MEDC are labeled with a unique identifier, generated by the State of Michigan, which allows researchers looking to perform analysis across multiple datasets to be fairly certain which records correspond to the same individual. However, this limits the scope of any analysis to these internal datasets and the variables they contain. In an instance where a researcher has access to an external dataset, they would be unable to investigate any relations between that dataset and MEDC’s data.
In addition to educational research datasets, MEDC also maintains a dataset containing the personally identifiable information (PII) of a large proportion of Michigan’s K-12 student population, including full names, dates of birth, racial/ethnic status, and addresses, each of which is associated with the state’s unique identifier. With this dataset, MEDC has developed a probabilistic matching model that allows it to match MEDC data with external data in cases where the external data each dataset contains at least some personally identifiable information in common.
The following is an overview of the process by which MEDC performs a probabilistic match between any incoming dataset and the PII dataset maintained in house. We provide a broad overview of some of the major concepts relevant to record linkage, including data cleaning, blocking, performing field and record level comparisons, and evaluation metrics and techniques.

Data Security Guidelines
Data made available through the Michigan Education Research Institute describe Michigan's children. It is critical that researchers keep data security at the forefront during every stage. Before submitting a research application, researchers should review these guidelines and work with their institution's IT and data security experts to make sure best practices are followed.
- In most cases, the use of cloud storage (e.g., Box, Dropbox) or work computers will not be approved for data storage. Talk with your institution's IT staff and ask for secured network storage.
- Describe how account management will be used to ensure only approved users have access to the data. Group-based policies (vs. allowing access on a one-off basis) are preferred. Your institution should have a role in issuing accounts that requires personal information (e.g., date of birth, address) to confirm the identity.
- How often will data access be reviewed and updated?
- Describe how you plan to access and analyze the data. We recommend only using "work" computers or remote desktops that are monitored by your institution's IT staff.
- How will you access data from off-campus? Whatever the answer, it should include the use of a VPN or other means to ensure end-to-end encryption of data.
