This post is a quick update on my in-depth review of group differences in the SAT, occasioned by the publication of the College Board’s reports on the SAT scores of the 2023 high school graduate cohort. Using national-level test data as well as data from selected states, I will examine how the most recent results relate to the trends that I previously identified.
1. Test participation
The following graph shows the numbers of SAT-takers from different groups across years, with the 2023 figures highlighted in red. The 2023 data are from this report, while sources for the earlier years are listed in Chapter 1 of the earlier post.
Even with the retreat of the Covid pandemic, you might expect SAT participation to be in serious decline as most colleges have gone “test-optional” or “test-blind” in recent years. However, the 2023 participation numbers actually point to a continuing recovery. The total number of test-takers in 2023 was about 1.9 million, which is clearly short of the record 2.2 million seen in 2019 and 2020, but well above the long-term participation trend. (Note that the SAT administration years refer to high school graduate cohorts rather than the actual dates when the tests were taken.) The recovery in participation was reasonably balanced across racial/ethnic groups.
2. National results
The following graph shows national SAT total score means by race/ethnicity in 1987–2023. The 2023 data are from this report, while sources for the earlier years are listed in Chapter 1 of the earlier post, where the various time trends seen in the graph are discussed in detail. In 2006–2016, SAT total scores ranged from 600 to 2400, while a scale of 400 to 1600 has been used in all other years. In the graph, the scores have been transformed so that the 400 to 1600 scale is used in all years.
The SAT means for all groups have tended to decline in the last few years, and this trend continued in 2023. Not even Asians are immune to this downturn. While this is consistent with learning loss due to the pandemic, in the national data this explanation is difficult to disentangle from changes in test participation. State-level data, to be examined next, may shed some more light on this phenomenon.
3. Results from high-participation states
In 2020, there were 11 states where 98–100 percent of high school graduates took the SAT. In 2023, the rate was that high only in the District of Columbia. However, 10 of the 11 states had a rate of at least 90 percent in 2023, so they still provide reasonably representative samples of high school graduates. The table below lists the high-participation states, with links to SAT reports for each state.
| State | N | Participation rate |
|---|---|---|
| Colorado | 57293 | 90% |
The figure below depicts total mean scores by race/ethnicity in the ten states in 2023. The states are sorted so that white means increase from left to right.
These ten states had ~100 percent participation rates in 2020, so it is useful to compare the results in the two years. This is done in the next graph. Sources for the 2020 data are linked in Table 3.1 of the earlier post.
With the exception of Native Americans, the mean scores of all groups decreased from 2020 to 2023, as measured by median scores across the high-participation states. This happened despite the fact that participation rates in 2023 were somewhat lower, with probably more attrition among less able students. The declining scores are consistent with the pandemic learning loss hypothesis. Alternative, it could be that students’ level of effort in the test is declining together with its importance.
The results for Native Americans may signal a turnaround for them after many years of peculiarly poor SAT scores. However, the sample sizes are small, and no similar reversal is seen in the national data, so it may be simply a selection artifact.
The final table shows numerical differences in SAT total score means between whites and non-whites across the two years. Positive gaps mean that the non-white group outscored whites, while negative gaps indicate a white advantage. It can be seen that non-whites generally gained ground on whites in the last few years, a reflection of greater declines in white than non-white mean scores.

| State | 2020 | 2023 | 2020 | 2023 | 2020 | 2023 | 2020 | 2023 | ||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Colorado | 50 | 55 | -167 | -166 | -156 | -166 | -212 | -162 | ||||
4. Digital SAT
In 2024, the paper-and-pencil SAT will be replaced by a new digital test. The new test is based on a multistage adaptive design, meaning that both the verbal and math sections are split into two parts, and the test-taker’s performance in the first part determines the difficulty of the items in the second part. A benefit of this design is that the same test score reliability as before can be achieved with fewer items and a shorter testing time.
According to the College Board, scores on the digital SAT will be equivalent with those from the current test, so that there will be no need to convert scores between test versions. This would suggest that racial/ethnic gaps in the new test will be very much like they are today. That remains to be seen.
The College Board has also promised to conduct various validity studies related to the digital test. As I discussed in my previous SAT post, published analyses on the predictive validity and measurement invariance of the current test are somewhat unsatisfactory. Hopefully research on the new test will be better.

In addition to the number of test takers, it is helpful to know what fraction of the respective cohort they represent, e.g. if approx 200k Asians took the test in 2023, how many didn’t?
In 2020, there were 11 states where 98–100 percent of high school graduates took the SAT. In 2023, the rate was that high only in the District of Columbia. However, 10 of the 11 states had a rate of at least 90 percent in 2023, so they still provide reasonably representative samples of high school graduates.
For some reason these high participation rates remind me of the old ‘A mind is a terrible thing to waste’ commercials for the United Negro College Fund that used to air on TV several decades ago.
It seems absurd to me that such a high percentage of HS grads take the SAT, especially if you think e.g. of an ‘average’ white HS grad having an ‘average’ IQ of 100 — there is simply no way someone with an IQ of 100 belongs at a university, yet one has to assume that with a participation rate close to 100%, plenty of them are taking the test.
Some sort of tracked education system makes a lot more sense — personally, I think it is pointless to attempt to educate the vast majority of black kids in an academic setting past the 8th grade — teach them how to read and write; build their vocabulary, including by making them read and look up words they don’t know; teach them to competently do basic arithmetic, including fractions. as well as something about the binary system and the basics of how a computer works; cover elementary biology, including Linnaean taxonomy and human biology; also something about the natural sciences, including a historical outline (physics, chemistry); show them how to use a library to find material and do a little research — a reasonable curriculum for this could be developed.
Then instead of an academic HS setting, allow them to choose some sort of career or vocational training.
Many people who go on to college and land in junk academia would be better off doing something similar — then university spending on that nonsense could be drastically cut too.
It looks like in the not too distant future 60% of college grads will be female — obviously they are heavily concentrated in junk academic majors.
