Ohio Longitudinal Data Archive — Access Procedures

Ohio Longitudinal Data Archive — Access Procedures

The OLDA data repository is comprised of state administrative records that have been prepared for use in research and evaluation. The OLDA is a restricted-use data source, available only for approved projects. The application process and data preparation may require several months.

Requesting Approval for Data Access

1. Complete and submit Section I of the OLDA Research Request for Data to ohioanalytics@oerc.osu.edu. Section I includes:

  • A brief (1-2 sentences) description of the proposed project;
  • Background information about the researcher and other research team members;
  • A statement of how the proposed project will inform state policy;
  • Purpose of the research and expected research products;
  • Requested data sets and expected linkage process.

2. Ohio Analytics will either decline the project at this point, or invite the research team to submit the remaining application materials:

  • Section II of the OLDA Research Request for Data which includes:
    • A research plan including the specific data variables the researcher will use, the research design, how the data will be used, and the targeted project timeline;
    • Acknowledgment of the data security plan detailing physical and electronic security and how access to the data will be handled.
  • An OERC and/or OLDA data sharing agreement (MOU) which identifies the legal terms of the agreement.
    • The lead research team member from each institution involved in the study must submit a completed copy of the data sharing agreement.
    • Each research team member must submit to CHRR a signed, completed OLDA Data Access Acknowledgment form prior to data access.

3. Ohio Analytics will review your application and determine if it meets our requirements. We may ask for additional details, so please allow sufficient time for review and subsequent revision. You will receive notification as to whether the project is approved or declined.

4. If the project is approved, complete the following steps:

  • Submit the signed data request materials to your Institutional Review Board (or equivalent) for human subjects review. The application process will be complete only when CHRR receives written verification that the research plan is in compliance with responsible research practices and has either been granted IRB approval or exempt status.
  • Submit to CHRR a certificate for each team member which confirms completion of Ohio State University’s online Collaborative Institutional Training Initiative (CITI) human subjects training (Social and Behavioral course).

Data Preparation and Access

5. CHRR staff will prepare data extracts for researcher access via the secured network as described in the approved OLDA Research Request for Data.

Results and Project Completion

6. In consideration of the use of this data, communicate findings to the relevant agencies as follows:

  • At least 21-days prior to sharing findings outside the approved research team (e.g. for presentation or publication), upload key findings to your secure account and send an E-mail notification to CHRR. The findings will be forwarded by CHRR to the relevant agency(ies) for their review. Altered presentations or publications of the same basic study and analysis may be reviewed by CHRR without the need for additional agency(ies) approval if all of the following criteria are met:
    1. The research questions and goal remain the same,
    2. Data tables and findings are not fundamentally altered, and
    3. The interpretation and findings do not fundamentally change;
  • Provide CHRR with bibliographic references to final publications produced from the data;
  • Submit a short (2-3 page) research brief describing the research, key findings, and policy-relevant insights that can contribute to the priorities of the data-providing public agencies and the OERC;
  • If requested, conduct a brief presentation of the findings to interested agencies.

7. The following acknowledgement must be included on any materials produced using data accessed from the OLDA:

The Ohio Longitudinal Data Archive is a project of the Ohio Education Research Center (oerc.osu.edu) and provides researchers with centralized access to administrative data. The OLDA is managed by The Ohio State University's CHRR (chrr.osu.edu) in collaboration with Ohio's state workforce and education agencies (olda.ohio.gov), with those agencies providing oversight and funding. Learn more about our sponsors in the OLDA Acknowledgment section.

8. All researchers will destroy all OLDA data from all computers by the research end date identified in the OLDA Research Request for Data. Once all of the data are destroyed, the Authorized Representative named on the last page of the OLDA Research Request for Data will sign, notarize, and return an OLDA Data Destruction Affidavit.
