Military Recruiting and NCLB

Among all the other fervor and complaints over No Child Left Behind, one that's been overlooked until now is that schools are required to give students' information to military recruiting agents.

A provision of President Bush's No Child Left Behind Act requires school districts to provide military recruiters with student phone numbers and addresses or risk losing millions in federal education funding. Parents or students 18 and over can "opt out" by submitting a written request to keep the information private.

The main objections are regarding the aggressive and sometimes deceitful recruiting practices of the military, and the probability that recruiters will target people of color and low income districts as said students are less likely to attend college after high school. The ACLU is suing the Albuquerque (NM) public schools for not informing the parents of the opt-out.

My concern is regarding privacy, and more specifically, how do the schools confirm the identity of the recruiter before releasing the students' sensitive identifying information? What if a serial pedophile decided to try some more flavors and dropped by an army surplus store on his way to an area high school? Or what if an identity thief wanted to open some new credit card accounts? If I had kids, I'd opt them out and grill the principal on how s/he releases the information on top of that!
