A 750 on an SAT Subject Test sounds like an amazing score, right? Not necessarily! Interpreting scores on the Subject Tests is more complex than it is on the general SAT. For example, an excellent score on the Literature Subject Test might look very different from an excellent score on the Korean with Listening Test.
Let's take a look at the average scores for each SAT Subject Test, and go over what they mean as you choose which tests to take.
Average SAT Subject Test Scores and Standard Deviations
First, let's take a look at the SAT Subject Tests in terms of their mean scores, standard deviations, and number of students who took them.
Overall, the average SAT Subject Test scores tend to be higher than the average scores on the general SAT since students who take the Subject Tests tend to be high academic achievers.
I've listed the SAT Subject Tests in order from highest average score to lowest. I've also included the standard deviations, which indicate how scores are distributed along the curve. A low standard deviation means that most students scored near the mean, whereas a high standard deviation means that scores were scattered across a broad range.

Your test scores don't exist in a vacuum. Rather, your scores are compared against all the other students' scores who took the same tests. This comparison is shown as a percentile, which will be part of your score report.
If you're in the 99th percentile, you scored better than 99% of students who took the test. Landing in the 50th percentile means you scored higher than half the students (and lower than the other half).
With that in mind, does a higher mean score suggest that a Subject Test is easier? Read on for what you can infer about an SAT Subject Test from a high mean score and a low mean score.

Your SAT Subject Test scores don't exist in a vacuum.
SAT Subject Tests With High Average Scores
As you can see in the chart above, the Subject Tests with the highest average scores are Korean and Chinese, which both have listening components. It's safe to assume these tests aren't easy if you don't speak Korean or Chinese!
But for people who do speak these languages, it seems that they are able to score very highly. The standard deviations for Korean and Chinese are both low, meaning that most students scored near the high mean of 760.
If you've studied Chinese or Korean but are not completely fluent, your personal high score of 650 or 700 will actually be in a pretty low percentile compared with everyone else who took the test. And if you're fluent and get 770, you might think it's an amazing score—but, actually, it's just average!
So what should you take from this? Unless you're a fluent or native speaker, these Subject Tests are probably not for you. And even if you are a fluent speaker, you should still definitely take time to prep, as you'll have to achieve an almost perfect score to stand out from the pack.
This advice pretty much holds true for all of the language tests, so don't get complacent even if you've been speaking the language your whole life. You still need to prepare to take advantage of this opportunity to showcase your language skills.
Another SAT Subject Test with a high mean score is Math Level II, at 698. Student scores show a fairly low standard deviation of 97. These results suggest that students who take the Math Level II really excel in math. Indeed, the test requires a strong grasp of concepts, as well as some extra test prep, to achieve a high score and percentile.
High average test scores mean that you'll have to aim for an extra high score to stand above and beyond everybody else. Now, let's take a look at low average SAT Subject Test scores.
SAT Subject Tests With Low Average Scores
One SAT Subject Test with an average score on the lower side tests a core subject that all students take in high school: literature. The mean score for the Literature SAT Subject Test is 614, and the standard deviation is almost double that of the Chinese Test. This indicates that some students scored a lot higher than the mean, and some scored a lot lower.
The Literature Subject Test is a challenging test that requires you to put in some serious study time to do well on it. But it is definitely possible to break away from the average, and a score in the 700s will put you in a high percentile.
To reiterate the point above, a score like 730 on the Literature test would be an excellent score, while a 730 on the Korean Test would be a good deal lower than average.
Another Subject Test with a low mean score—in this case, just 610—is Math Level I. Compared to Math Level II, which has a far higher average of 698, it seems that those who take the Math Level I Test aren't typically as strong at math as are those who take the Math Level II Test.
Find Target Scores for Your SAT Subject Tests
By knowing these average scores and thinking about percentiles, you can set specific target scores for the different SAT Subject Tests you're planning to take. If you're deciding among several tests, try to aim for those with a medium to high standard deviation. If the test has a low standard deviation and thus less variance, your scores will look a lot worse if you underperform.
Remember that schools are not using your Subject Test scores on an absolute scale but rather are considering how they compare with those of other students who took the test. This information of average test scores and standard deviations is important for understanding this comparison and for planning your target scores and the percentiles they are likely to fall in.
Generally speaking, a great SAT Subject Test score is one that's in at least the 80th percentile, while a good score is one that's around the 70th percentile. As our article on good SAT Subject Test scores indicates, percentiles can vary a lot for different SAT Subject Tests, so it's important to take this information into account as you set your target score for a specific test.
Usually, regardless of what schools you're applying to, it's a good idea to aim for a Subject Test score in at least the 700s.
Finally, you might want to try to research the average SAT Subject Test scores for the colleges you're applying to. Note, however, that most colleges don't report this information, so it's likely you won't find anything online. In this case, assume that you're going to be needing a score in at least the 70th percentile (80th-90th percentile for more selective schools).
The Final Word: How to Prepare for SAT Subject Tests
One step you can take as you prepare for the SAT Subject Tests is to check out our article on the easiest SAT Subject Tests. This guide further breaks down the data so you can see how it affects your choice of Subject Test.
Secondly, make sure to prepare well for these tests, even if a subject is your best subject or you speak a language fluently. The College Board offers a helpful breakdown of the SAT Subject Tests along with some sample practice questions.
Finally, schedule your Subject Tests at the end of the school year, when you're studying the subject and the content is still fresh in your mind. Since you'll be competing with high academic achievers, you want to put yourself in the best position to succeed.
