FERPA and confidentiality of information when university officials contact school I have a reason to think an official from a university I previously applied to is potentially stalking me. His previous actions and attitude had made me uncomfortable. We live in the same town and at a talk I attended recently, he asked if I am a grad student at University X now (the school I chose to attend instead). I did not answer and largely tried to avoid them but I do indeed attend university X. The thing is, I really don’t want them to contact me at my university/lab so I do not want them to know my information related to this school. I asked the office of registrar to make my directory information confidential. It took a few days and I have also been told that FERPA confidentiality has some limitations and it seems release of information to educational institution officials is one of them. As long as a university official contacts the school with an education-related interest (it would be easy to fake one, I think), apparently revealing my information is at the discretion of the school and not governed by FERPA. Is this correct?

If they were to contact my university as an official from a different university / department head, would they be told any of the following information:
- My current address and phone number
- The department and the labs I work in
- My office address and office phone number
- Dates of attendance
- Classes I am currently taking and their schedule
etc?
Some of the information you mention might be considered public information and not "educational" and so not covered by the law. Your courses, and similar are probably covered, but FERPA is more intended to cover your performance. But if you are concerned for your safety, for example, you need legal counsel. The university may be able to provide it via some office dedicated to student services. But for a serious concern you may need to contact a lawyer or even the police. In some situations, a university can bar a person from school facilities, of course. 

It may be a crime for someone to use the university systems to harass or stalk you, but if they are willing to risk it, you would be at risk, so you need to take precautions. But for serious interventions, you probably need some evidence or corroboration by others. Some people are just awkward rather than creepy, but only you can really judge that.
