During my early years, my Catholic school in Puerto Rico did not conduct any field trips. I first enrolled in the public school system in Florida at the age of ten. They did conduct field trips; each of these required a signed parental consent form. In this regard, we simply brought that consent from home and simply asked her to sign it. My mom didn’t really speak (or read) English. Truthfully, she didn’t really know what each particular field trip entailed, though she implicitly trusted us not to abuse that trust. We never had her put her name on a blank check or sign away the car or house.
During my senior year in high school, there was a similar classroom session for our Health class. This particular class was a requirement for graduation. However, this specific lesson required parental consent; those who did not get consent would spend it in the library. Like all other parental permission forms that preceded this one, I simply handed the paper to my mom and asked her to sign it. The lesson talked about human sexuality, had pictures of circumcision, childbirth, etc. While I’m sure some students didn’t get consent, the ones who remained didn’t seem especially distressed.
