M7 MBA Programs: Class Profiles, Essay Requirements, and What the Label Hides

"M7" is an informal name for seven MBA programs: Harvard, Stanford, Wharton, Chicago Booth, Kellogg, Columbia and MIT Sloan. None of their official class-profile or application pages uses the term. Their own data shows why the label misleads: test averages cluster tightly, while selectivity and required writing differ enormously.

This page puts each school's published numbers in one table, with the class year for every figure, then puts each school's 2026–27 writing requirement next to it. The argument is simple. If the scores barely separate these schools, they will barely separate you within them either. The part of the file that differs most, from school to school and from applicant to applicant, is what you write.

The M7 by their own numbers

Every row comes from the school's official class profile, read on September 24, 2026. "Seats ÷ applications" is my arithmetic from the school's published applications and class size. None of the seven publishes an admit rate, so an offer rate is not shown; because some admitted applicants decline, each school's true offer rate is higher than its seats ratio.

Arithmetic: 943 ÷ 9,409; 434 ÷ 7,259; 888 ÷ 7,613; 635 ÷ 5,876 (Booth's full-time count; 695 ÷ 5,876 = 11.8% if joint-degree students are included); 982 ÷ 7,477.

Read the table with its caveats. Harvard, Booth and Sloan report medians; Stanford, Wharton, Kellogg and Columbia report averages. Sloan's page is still headed "Class of 2027," but the chart embedded on it is labeled "MBA Class of 2028" and "Updated: September 2026," so its figures describe the class entering in 2026 while the other six schools show the class that entered in 2025. Booth's page carries two test presentations that disagree: a summary block (73% GMAT, average 729; 26% GRE, average 164 Quant / 163 Verbal) and per-edition blocks (14% older GMAT, 39% GMAT Focus with a 675 median, 42% GRE with 163 / 161 averages) whose shares, unlike the summary's, fit the page's own footnote that percentages "do not total 100." The table uses the per-edition blocks; Booth does not say which set is current. Columbia counts January and August entrants together. None of these differences is hidden; each school labels its own figures, and comparing them without those labels is how most "M7 comparison" charts go wrong.

What the numbers say about the label

Where "M7" is accurate: test profiles. Every GMAT Focus figure above falls between 675 and 690, and every GRE figure between 161 and 164 per section. Work experience sits between 4.9 and 5.3 years. On the measures most applicants obsess over, these seven classes are close to interchangeable.

Where "M7" misleads: selectivity. Stanford fills roughly 6 seats per 100 applications; Columbia fills about 13. That is more than a twofold difference inside one supposedly uniform group. Class sizes run from 434 (Stanford) to 982 (Columbia). Two of the seven do not publish an application count on their profiles, so no honest table can rank all seven by selectivity at all.

Where "M7" misleads most: the writing. The required written work ranges from four 300-character answers to up to 1,000 words, and is measured in words, characters and seconds of video. A group label that treats these as one application encourages the most expensive mistake in a multi-school round: writing one essay and trimming it seven ways.

My opinion: use "M7" as a search term and nothing else. Choose schools on the evidence above and on what each one asks you to demonstrate, not on membership in a list that no school publishes.

What the writing must do when the scores are table stakes

If the enrolled classes' test figures sit within about fifteen GMAT Focus points of each other, and every school says it reads the whole file, then a strong score gets you read; it does not get you chosen. Three consequences follow.

1. Each set tests something different, so each needs its own core claim. HBS names its essays after its three criteria. Stanford asks what matters to you and why. Wharton and Kellogg both ask what you will contribute to classmates. Booth asks you to be memorable in 300 characters, and Sloan asks for a business letter backed by professional examples. One story can appear in several sets, but the claim it proves must change each time.
2. Short boxes punish vagueness the most. Columbia's 50-character goal field and Booth's 300-character answers leave no room for a warm-up. Write those first; if you cannot state your immediate goal in 50 characters, your 500-word goals essay is not ready either.
3. Ratios should shape your list, not your prose. A school filling 6 seats per 100 applications and one filling 13 are different bets. Put that into where you apply, and keep it out of how you write: an essay that sounds anxious about odds reads worse at every school.

A decision procedure for this week

1. Cross out the label. List the M7 schools you are considering with their seats ratio and required writing from the tables above.
2. Check your score against each school's own figure, then stop test prep if you are near all of them.
3. Group your list by writing load: long reflective sets (Stanford, HBS), contribution-centered sets (Wharton, Kellogg, Columbia), and short-form or letter sets (Booth, Sloan).
4. Write every short-form answer first, because they force your goal and identity into a sentence.
5. Draft each long set around its own core claim and run an overlap check across schools.
6. Get a structured read of each set against its school's criteria before polishing.

For step 6, you can run your own drafts through GradPilot's free review against each school's rubric, linked in the table above. The free review gives qualitative feedback on how a draft meets that school's prompts; it does not predict admission, and your essays remain your own writing. MBA essay review covers a multi-school round. For the three schools most searched by acceptance rate, see the single-school pages on Harvard, Wharton and Stanford GSB; for test choice across these schools, GRE vs GMAT for the MBA.

Several M7 schools run joint degrees with T14 law schools, each with its own application structure; see JD/MBA programs at T14 and M7 schools.

FAQ

What are the M7 business schools?

The informal "M7" grouping is Harvard Business School, Stanford GSB, Wharton, Chicago Booth, Kellogg, Columbia Business School and MIT Sloan. It is not an official category, and none of the schools' own class-profile or application pages uses it.

What is the acceptance rate for M7 schools?

None of the seven publishes an admit rate on its class profile. Five publish application counts and class sizes, giving seats-per-application ratios from 6.0% (Stanford, Class of 2027) to 13.1% (Columbia, class entering 2025). True offer rates are higher, because some admitted applicants decline.

Which M7 school has the fewest essays?

By length, Chicago Booth: four required short answers of 300 characters each, one tied to an uploaded image. MIT Sloan requires a single 300-word cover letter but adds a video statement, a video question and an organizational chart.

Do M7 schools prefer the GMAT or GRE?

Harvard, Stanford and Wharton each state on official pages that they have no preference between the two tests. Scores of either type appear in every class profile above.
