We're also a uniform school, but only means white or navy polo shirt and khaki/navy/black pants/shorts/jumpers. We ask for outgrown items to be donated. We have a social worker at the school who pretty much knows who needs what.At Christmas time, she has an angel tree that lists only the gender/age and anyone can take an angel and return the unwrapped items for the social worker to distribute.
The clothes are available for any child who might need them.They're kept in bins in the teacher mailroom, sorted by sizes. If a child should have an accident etc., the teacher can find something for them and it's usually intended as a loan and expected back. This doesn't always happen, but it's not a big deal since we never seem to run out.
We actually prefer that PTO is ignorant of who are the needy families in the school. People, even well intentioned ones, are still human. Generally, if there is a special need( we have been asked to donate food and cash before), the principal will give us general info and ask if we can help. We don't really need to know specifics since we know the principal wouldn't even ask if there weren't true need.
You're right about violating privacy--we've actually had offers refused/been read the riot act when we directly approached a family that we KNEW were in true need. We'd inadvertantly humiliated the family. That taught us to leave it to the social worker & principal--that's their job.
We asked the school about having these families volunteer to work at the sale (we get $25 uniform credit per 4 hours worked at the new uniform sale) but were told that the school is not allowed to give the names of families that get free uniforms
The way around this would be to let everyone know regardless of their income and I'd bet that you'd have more volunteers than you need.I'd say that the upper income families wouldn't apply, but the lower income probably would. Those who volunteer but don't really need the credit could always donate their time to a pool that purchases the uniforms and PTO can leave distribution to the school's discretion.
