The Freedom of Information Act (FOIA) gives you the right to access information from the federal government. It's a way for citizens to keep a check on the government. These can be very powerful in finding information that the government may be withholding but is also not an absolute right. There are considerations for things like national security.
You can submit your own FOIA request! FOIA.gov
So, you've done all your research and the information you want isn't available anywhere.
It's time to file an FOIA Request.
If you are requesting the information for educational or noncommercial purposes, you should make that clear. You also need to indicate how the requested information will be beneficial and how/if it will be disseminated (for example, at URAC). To expedite the process, you should attach proof of your student/faculty status. You can also request they consult you on the anticipated costs and determine alternatives to reduce the cost.
Check out this In-Depth Guide from Public Citizen walking you through the FOIA request process.
