They are looking for your record of compliance with the TSA's requirements for (1) annual Security Awareness Training (2) records of having examined certain students' passports or birth certificate/drivers license combos to determine citizenship and (3) your record of complaince with the TSA's requirements for training foreign students.
They are treating you like a flight school because, under the TSA regs, you =are= a flight school.
I'm assuming you are generally familiar with this stuff. If you need more detail...
