Every family handles this differently, of course. I have 2 Ds (15 & 20). We told them that we prefer that they don't date outside of a group setting until they are 16. Although D20 did have a boy ask her to dinner at his house once at 15 (he lived with his grandparents, so that was okay). Worked out okay for both of them, as neither met anyone they really wanted to "date" prior to that anyway. They sometimes used it as an excuse when they didn't want to go out with someone, too. Hasn't seemed to cause any relationship issues, D20 has a fabulous BF she met in college.
I think that you setting a rule like INTparent makes it easier for her to say no AND easier on the boys feelings. I always hated hurting people's feelings and as a young teen would either sacrifice my feelings or be cruelly dismissive - it would have been nice to "blame it on my parents." :-)
