Perhaps your best bet might be to poll other districts in your area (or other schools in your district) and find out what they allow. Assuming that works in your favor, you can present your findings to your principal. If the school across town has found a way to deal with the liability issues, then it should be easy enough for your principal to talk to that school's principal and find out how they have worked through it. (I've gone through the clinic training in our district, and never even had to sign a confidentiality agreement, although they certainly did emphasize confidentiality, and my district is one of the 15 largest in the country.)

Though I can not answer specifically, I do know when this became an issue a few years ago in our district, it was discussed with our school board. I feel a lot of times that an individual school or secretary willl put up barriers because they don't want to deal with something so you need to step up to the next level. Start out nice and just ask how you should handle it. If you don't get any answers, try to form a concerned parents committee in your school.

I am a parent volunteer trying to get the clinic up and running. The clinic at this school used to be 4 hours everyday, and now becuase of office politics, it is during lunch hour only.

The problem is privacy. The school office secretary says the emergency forms contain private information, which can not be shared. I have had the volunteers sigh a confidentiality agreement, but the office continues to throw up privacy issues.

The volunteers would like to know who has serious health issues, so a stomache ache is not assumed to be nerves, when it could be a peanut allergy.
Also, the school office, because it refuses our help, is sending sick children back to class if they can not get ahold of a parent. That is just wrong.

So what are other parents running clinics doing to get privacy issues addressed, while still having access to important information.
The sick kids, and I thank you for any input.
