Middle 80
Also called middle 80% · mid-80 · 10th to 90th percentile · middle eighty
Take the same cohort you used for the mean and median: for GPA, U.S. 4.0 cumulative figures only; for GMAT, testers with an official one-sitting score; for work experience, all matriculants including zeros. Sort the values. The 10th percentile is the point where 10% of values lie below and 90% above. The 90th percentile is the reverse. The published range is those two numbers.
Middle 80 is the range from the 10th percentile to the 90th percentile of a class-profile number. GMAC’s GME Admissions Reporting Standards define it by dropping the lowest 10% and the highest 10% of values. Use it to see where most of a class sits, not where the extreme admit sat.
How is the middle 80% built?
Take the same cohort you used for the mean and median: for GPA, U.S. 4.0 cumulative figures only; for GMAT, testers with an official one-sitting score; for work experience, all matriculants including zeros. Sort the values. The 10th percentile is the point where 10% of values lie below and 90% above. The 90th percentile is the reverse. The published range is those two numbers.
GMAC’s GPA example: the full range is 2.5 to 3.8 on a 4.0 scale. After cutting the bottom and top tenths, the middle 80% is 2.9 to 3.6. Someone with a 2.6 is inside the full range and outside the middle 80%. That person can still be admitted; the middle 80% is a description of the class, not a fence.
The same construction applies to current-edition GMAT totals (205–805) and to months of work.
Example: 100 GMAT testers. The 10th score from the bottom is 615, the 10th from the top is 735. Middle 80% = 615–735. The median might be 675. A candidate at 645 is inside the band and below the median. A candidate at 595 is below the band and still might be admitted with the rest of the file. Reading only the median would have hidden both facts.
How does it differ from median, mean, and full range?
The median is one point. The mean is one point pulled by tails. The full range is two points owned by the single lowest and single highest people, which is why a 205 and an 805 make a useless GMAT range. The middle 80% throws those two tails away on purpose.
| Statistic | What it hides | GMAC asks for it? |
|---|---|---|
| Mean | Spread | Yes |
| Median | Spread | Yes |
| Middle 80% | Only the outer 20% | Yes |
| Full range | Almost nothing useful | Not the standard |
Common errors
Treating the lower bound as a cut score. Comparing a middle 80% from testers with a median that silently includes waivers. Publishing one GMAT range that mixes 10th Edition 720s with current 675s. Using middle 50% and calling it middle 80%. Reading a 2.5–3.8 GPA “range” as if it were the GMAC band.
FAQ
Is the bottom of the middle 80% the minimum GMAT or GPA?
No. Ten percent of the reporting cohort sits below that number by definition, and more people sit below it if you count non-testers. Schools admit below the band every year when the rest of the file is strong. Use the band as a location check, not as an eligibility rule.
Why not just publish min and max?
One outlier owns each end. GMAC’s GPA example shows why: 2.5 to 3.8 looks wide; 2.9 to 3.6 is the class. The same problem hits GMAT when a single 805 or a single waiver-adjacent low score is allowed to set the range. Middle 80% is the compromise that still shows spread.
Does work experience use the same method?
Yes. GMAC says to calculate mean, median, and middle 80% for full-time months since the undergraduate degree, zeros included. A class that enrolls deferred students will have a lower 10th percentile than a class that does not. That is information, not a defect in the formula.
