For those parents who have no divine parameters regarding sexual behavior, or whose liberal outlook concedes the sexual abandon of their children, then perhaps this is the best anyone can hope for to stem the tide of unwed mothers and aborted babies. Of course, all of this is moot in the case of the pregnancy pact because their goal was to deliberately conceive, not to enjoy inconsequential intercourse.
So did the decision help anything? Not really, except that kids may now feel freed up to explore their sexuality with other kids wherever they can get alone, and with the seeming encouragement of both parent and principal.
Call me old-fashioned, but I still think that kids ought to be taught abstinence, expected to maintain abstinence, and should be protected from rambunctious school chums of the opposite sex who would like to help them overcome their abstinence.
