Same is true of my kids schools. Every year, we have to fill out (on paper) the same extensive forms to collect parent names and addresses, phone, email, whether you are homeless, what your racial makeup is, on and on.
No option for "everything is the same as last year" and they completely flip out if you don't return the forms.
My employer's HR collects my date of birth and SSN 4-5 times a year. Why? So some clerk doesn't have to look it up.
