@gearmom . Your child will succeed because you are definitely great mom.
@Jayku You’re so sweet. I have 3 boys 8th, 11th and college junior. Very nice when the older children inspire the younger ones. I’m glad her confidence was boosted. That can be hard when you have a high performing older sibling. And it really could be that she’ll score super high on the test. Enjoy these years with her. They go by really fast.
@gearmom . Fighting!
Again I ask…what is the REASON for having a 13 year old take the SAT?
TBH, unless there is a GOOD reason for taking the real test, I would encourage your 8th grade to do other things.

Lots of GOOD advice on this thread which was posted upstream. You might want to read it.
@thumper1. Thanks for your AD. A few students in 8th grader got already perfect score.Of course they are special. My D is not special but she is very challenging and aptitude.I belive that she can do that if its level is like college board practice.However if it is harder than it, this experience helps her future. She also experienced ACT practice through freeonline examples. She says it is easier than SAT. I will decide after reading.
@Jayku Congrats to your brilliant child.
@thumper1 is correct that I received excellent advises on my thread.
I’m in a similar situation where my S (8th grade) scored high on SAT practice which force me to think about college prematurely. I had thought if my S can get into Harvey Mudd or Caltech it would be close to home and that would be perfect. Because the price tag is very hard to swallow plus the competition is so outrageous, I think UC’s and Calpoly SLO are great choices too.
I see that your answer had been answered, and I looked into that question myself. Yes, your D will be able to take the real SAT but because she’s not yet high schooler, if you want the score to be reported, you need to put in a request.
I took want to see if my S good practice test score is a fluke or reality. I think to myself, maybe collegeboard.com makes the tests easier to boost kids confidence. 
I believe you said you have another D that’s going to UCB. I am wondering if you know with all her AP exams how many UCB credits was satisfied and/or how many semesters was knocked off?
I think we are very lucky to find this great forum with so many caring and passionate parents. I just sign up 2 days ago and feel I can come here for any questions regarding my children’s education. Majority of the people commenting are super nice, especially the ones with “mom” in their login name. Some will try to put down your child for no reason, which I find hilarious, like they have nothing better going on in their lifes. LOL.
Good luck to you and your wonderful D!!
@Jayku who told you that a few students in your kid’s 8th grade class already got perfect scores?
This just isn’t very common…and the likelihood of “a few” 8th graders from YOUR school doing so on the real SAT test is,…well…minimal.
Plus…who cares? Is this a contest? Is your kid trying to keep up with what supposedly others say they have done?
Your kid is a 13 year old who is in the 8th grade. If this kid is going to get a perfect SAT score now…that same kid will get a perfect SAT score in 11th grade. What’s the rush?
There are SO many other things that are important for these young teens to be doing than standardized tests. So many.
I have to say as a mom of a 9th grader taking the ACT this morning, that I totally agree that there are lots of important things for young people to do besides taking standardized tests. If they can get these tests out of the way early and focus on the exciting opportunities in high school, great! I know my son, now in college, would have liked to have had the SATs over with sophomore year so that there were no conflicts with track season, robotics, and all the other more enjoyable elements of high school for him.
Of course it depends on the child. My daughter commented that compared to piano recitals, taking a 4-5 hour test was no big deal. For many, waiting a couple of years is the best approach.
I agree. If OP’s D can score 1600 in 8th and it applies just as the same as if she takes it in HS, why not? Get it out of the way so it’s not in the back of OP’s or D’s minds. In my opinion, getting a perfect or near perfect score as an 8th grader will impress colleges. By the way, I think OP means Owner of Post, right? I’m new and I see a lot of people use it. 
My S does did very well in practice also (1550+ x 3), but I don’t think he should take the SAT because there’s math courses that he needs which he hasn’t taken yet. He draws blank when he sees those questions on the tests. OP is different since his/her daughter learned math beyond her grade level.
1 less thing to worry about means more time to do other interesting and exciting things. I’d do it if my S was ready.
OP…original poster.
Colleges will also be looking at more CURRENT info. As a matter of info…when my kid was in HS, the College Board actually redid the SAT…adding the writing section (which has since been removed). If my kid had taken the SAT as an 8th grade, colleges would NOT have accepted it for college admission purposes…because they wanted the NEW test as of a certain date…which was after 8th grade. Just FYI.
So…sure…take the SAT now…but do understand that if it’s revised…again…within the next couple of years, your kid just might be taking it…again anyway.
@thumper1 . It is not correct. If they got good score in 8th grade, it will be useful. College doesn’t consider that only SAT is not important but AP and other extra work. They should keep studying .And if they got good score which is not coincidence that they can get also good score in high school. So it might be good experience for youngstudents.
I think the ONE reason it is useful to take it is because it can help a student qualify for programs like TIP, Northwest Academic Talent Search, CTY, etc. One of my kids did it, and was able to use their score to attend Davidson THINK for two summers. She had a hard time finding friends with her interests and matching intellect while growing it, and it was her most treasured EC because of that. She is still friends with several students she met there even many years later when she is in grad school. I believe her THINK experience did help her focus her college search – she had a better idea what kind of college experience she wanted (smartest people, lots of hard work). That informed her essays and “why college x” answers as well.
I would not take it for other reasons. It is just ego if you don’t intend to have your kid use it for a program admission. Colleges don’t care about the score achieved at that age as well. And don’t feel like your kid needs to practice. Doing some prep before the PSAT when they take it in 11th grade is plenty soon enough for starting SAT prep. A kid who is a strong tester is going to very well then – no need to burn them out or do it for bragging rights now. Colleges don’t just want strong tester/highest grades/most APs. They want students who are interested and interesting – endless studying does NOT guarantee admission to top schools.
Some of the MIT summer programs for high schoolers asked about SAT scores so if a kid wants to spend 3 hours of a Saturday taking the SAT it may end up being handy. My kids took the SAT in middle school to qualify for CTY summer programs. The older son loved them and did them for three summers. Younger son said “Why would I want to go to school in the summer?” and so he did different things in the summer. When they took the SAT in 11th grade they were comfortable with the format and confident that they would do pretty well.
Kids take the ACT and/or SAT in middle school for gifted and talented programs to find out where they are at. Some reach the ceiling with top scores like your child (if only on a practice test). The only reason to take the real test now is to qualify for summer gifted programs. The program of interest depends on your region. Duke, Johns Hopkins and Northwestern all sponsor talent searches for their areas (south, NE and Midwest). There are others I’m unaware of.
I wouldn’t bother taking the test formally/again at this stage. One can overtest for no reason. If she does this well now she’ll do well later. btw- a perfect score does NOT mean admission to elite schools (son got the 2400 SAT Dec senior year-long story for why he retook it, had 35 on ACT).
At this stage you use the official scores for program eligibility, not college. Please let her enjoy her childhood and do not let her obsess about testing.
Do you live in the United States?
@ wis75 @intparent everyone has different opinions. All college requires SAT ACT GPA etc. But perfect score can go top school that everybody know and every who wants to get high score definitely doesn’t desire IVY or top schhol. Some children enjoy challenging academic and,they also have very different aptitude from others. I just doubt that real SAT is harder than practice. My D can challenge If it is not. But I can not believe yet.
I am sorry. Top score isn’t guaranteed to go top cllege.
college but I guess that can have more chance.
@jayku Perfect test scores by themselves
will not gain a student admission to a top schools. Not even top scores with top courses. It is far more nuanced than that. They want students who are well-rounded with outside interests.
