Most people don’t know this, but I have/had 3 piercings since I was 14-15. I got all of them done with a parent’s permission, and I regret every single one. I wish somebody made me wait until I was 18 (or 25) because I would not get a hole poked in me!
I pierced my own ear at 15 with a piece of cork and a safety pin. I don’t regret it and still wear an earring on occasion.
Everyone’s different 
But not everyone is weird.
in their own little way…are too 
I’d say NO. Not while I pay the bills and provide food and board.
This desire would also send up all kinds of danger/warning flags to me.
Actually, I 'd be freaking out.
(this is the reaction of a Mom to two almost 30yr old daughters- one who wanted a tattoo 10 years ago and as a professional geophysist/engineer is very thankful today that she was not allowed to get one. The other daughter was a good student who sent up the same warning flags and 10 years later is a recovering drug addict. )
She should work for the grades for herself, and the reward of knowledge and increased self-esteem. A pierced tongue does not send out a favorable impression to most folks.
I’d definately try to delve into just WHY she wants this done. Don’t ignore it thinking “not my kid”.
Thanks all, I appreciate the input! I think I’ll probably take her up on it.
She’s a smart kid, and for the most part has her head on straight. She
knows that when I make a deal I stick to it, so if she doesn’t make the
grade she won’t press the issue. I’ve found that if I am fair, open minded
and consistent, she is much more likely to share her inner thoughts and
experiences with me. This gives me more insight into things that could
become real problems for her, and makes her more likely to listen to
my objections on the important things in life. I guess the real crux is
determining what those important things really are.

I would never have a piercing. I firmly believe that evolution/intelligent design* has given me exactly the number of body holes I need. (Added to which, I’m a complete wimp) 
*delete as applicable
Piercings are forever and I have known several people that regret ever getting them.
Piercings seem sort of “slutty” to me, and I would never want a daughter (or son, but the ex-wife gave in) to have one.
I would vote no. And stick to it!
If prisoners were given tongue piercings when they were incarcerated, we’d call it cruel and unusual punishment.
Man, some of y’all just need to lighten up a bit
simple rebellion is going to happen in your teenager whether you want it to or not (and whether you think you can controll it or not), and the chances are likely that if your child appears to not be rebelling in one form or another they are likely doing it BEHIND YOUR BACK!
And for the record…tatoos and piercings are not an “if-then” indicator of drug abuse or any other kind of distructive behavior, for that matter. By thinking so, you are including myself and anyone else who has ever done anything remotely rebellious into that category. Generalizing and associating your child’s natural rebellion may in fact encourage the type of behavior you were hoping to avoid. By keeping a cool and tolerant head about your child’s rebellion you increase the likelyhood that they will continue to come to you about those types of dicisions rather than making them on their own. 
I like your comments.
I have 4 sons, one 22, the rest teens.
I have used your rationale with all of them, and find it works well, even though each one is very different from their brothers.
My eldest came home from college with a pierced tongue.
So what?
He no longer wears the stud, (broke up with that particular girl friend) and is none the worse for wear.
He doesn’t have a tattoo, but what if he did?
I have had a tattoo since I was a 20-something ~ at least it is in a place covered by clothing, and no I have never regretted the tattoo, in fact I have always liked it. In the realm of things, a piercing is much more benign, take out the stud and it’s gone. What about a tattoo? I have seen elderly women (pt’s of mine) with tattoos on their wrinkly arms, etc. and no it is not attractive even if it once was when they were young. Tat ink discolors, your skin ages, and no, you are not likely to go through the expense and time involved in having it removed.
(Sorry for the little rant, I am very tired of seeing highly visible, unattractive tattoos on young people who will likely be entirely different individuals with entirely different lifestyles 20 years from now. 
)
So if all your daughter wants is a tongue piercing and is willing to discuss it with you, and study hard into the bargain, then I think your decision is a good one.

edited to say that despite my feelings about tattoos, my sons have the right to have tattoos too. Their opinions don’t have to be the same as mine.
Tatoos and piercings are all fine and good… even better when the individual getting them are mature enough to decide to get 'em and maintain 'em properly. That age could be 10, or it could be 65+.
But while a child is in the care of their parents or guardians, they ought to abide the by the rules set down for them… and parents ought to stick to their guns, enforce these rules and not give in… what kind of message does that send to the kid?
Hmm…I wonder what Amar was rebelling against.
I think he saw too many red kitties, and decided the world needed a pink kitty!
I agree, if a rule has been established then it should not be compromised,
however, this was a new situation and therefore open for discussion.
And it sounds like the discussion was reasonable.

Nearly everyone I’ve seen/heard with a tounge piercing has a pronounced lisp from it.
All you have to do is learn to talk with it in…
it’s not hard.
I’m just puzzled by this, and it’s been nagging at me since I read it. The implication seems to be “piercings are bad..after all we wouldn’t force prisoners to do it”. I don’t mind people having an opinion that tattoos or piercings are good or bad…that’s their perogative. I just don’t see how the prisoner argument logically follows.
Many things people choose to do things that would be considered “cruel and unusual” if people were forced to do them. Tattoos, if forced on a prisoner by the state, would likely qualify. Yet, there’s no doubt that many (if not most) prisoners choose to get tattoos done by their fellow inmates.
Tattoos are clearly “seedy” to some people, though, and thus a bad example. So consider this: Bungee jumping…can you imagine the outcry if we tied small-time burglars to a harness, and threw them off of a bridge as punishment, and a certain percentage died every year because of the practice? And yet, people pay good money to do this in the civilian world. Skydiving? Same thing. I can imagine the judge: “Traffic ticket, eh? ok..give the man a parachute, and throw him out at 25,000 feet.” Thrill rides at a theme park? Same thing: “Shoplifter eh..ok, into the Barrel of Monkeys…3 minutes at 3 Gs rotation..that’ll learn ya.” Each of these scenarios would likely raise a huge stink if forced upon prisoners, and yet most people would not consider skydiving, bungee jumping, or thrill rides inherently bad (dumb maybe…but that’s a different argument).
I just can’t see the logic of the comparison.
When I worked at the prison, I knew tons of inmates that would line up for free piercings!
