Yale Secret Societies: Tap Day, Skull and Bones, and the Real Function of the 'Tomb' Houses

Walk down High Street between Chapel and Elm on a Sunday morning and you will pass a windowless brownstone fortress with a single iron-grilled door, the entrance set back behind a low wall. There is no name on the building, no hours posted, no contact information. It looks more like a small mausoleum than a house. This is 64 High Street, the Skull and Bones tomb, and it has stood on this corner since 1856. Two blocks south, on College Street, you can find a similar but slightly grander Egyptian Revival pile — the Scroll and Key tomb at 444 College, finished in 1869. A few minutes north, on Prospect Street, the slightly more domestic-looking Wolf's Head tomb at 77 Prospect went up in 1924 in a hybrid Tudor-Gothic style. None of the three buildings has windows on the public-facing walls; all three have heavy iron gates; and on a normal weekday morning you can walk past them without realizing they exist. They blend into the surrounding streetscape because Yale has had two centuries to absorb them into the campus's neo-Gothic vocabulary.

These are the three oldest of Yale's senior secret societies — Skull and Bones, founded 1832; Scroll and Key, 1842; Wolf's Head, 1883 — and along with about a dozen newer or junior societies they constitute one of the most-discussed and most-misunderstood institutions in American higher education. The popular imagination treats Yale's secret societies as the visible part of a conspiratorial Bohemian-Grove apparatus that controls American power; the Skull and Bones membership rolls include a Bush, a Kerry, a Taft, a Stimson, plus several CEOs of major banks and one or two CIA directors, which is enough to fuel decades of online speculation.

The actual story is less dramatic and more useful. The senior society system is Yale's mechanism for structuring senior-class social capital after the academic curriculum has homogenized the undergraduate cohort. The selection ritual happens in late April of junior year, the activity happens in the windowless tomb houses on a strict twice-a-week schedule for the senior year, and the function — historically and to a quieter extent today — is to put fifteen seniors with very different backgrounds into a room where they have to learn each other's full life histories before they graduate. What they do with that connection afterward is up to them. The Wall Street and DC career-ladder version of the story is one outcome; for most members the lasting function is closer to a structured friendship of a kind American college rarely produces.

This article walks through Tap Day (the formal selection ritual), the tomb houses (what actually happens inside them), and the question international students often arrive with — whether membership matters for what comes after Yale, and whether they are realistic candidates.

The Senior Society System in Outline

Yale's senior society system organized itself in three waves. The first produced Skull and Bones (1832) and Scroll and Key (1842), founded by undergraduates dissatisfied with the existing literary-debate societies that had dominated Yale's social life. The second, in the late nineteenth century, produced Wolf's Head (1883), Berzelius (1848), and Book and Snake (1863). The third, beginning in the 1930s, produced newer societies including Elihu (1903), Manuscript (1952), and Sage and Chalice (1989), plus several "underground" societies without dedicated buildings.

There are roughly fifteen senior societies active today. Each takes about fifteen members of the rising senior class in the spring of junior year. Yale's undergraduate class is about 1,500 students, so 200–240 seniors are tapped each year — about 15% of the class. The selection criteria differ from society to society but the differences are gradient rather than categorical; most tapped seniors would have qualified for several, and the matching process is a delicate negotiation.

The activity is structured around two dinners a week — typically Thursday and Sunday evenings — inside the tomb. Each runs roughly three hours; across a senior year this is about 180 hours of structured time together, more than most undergraduate seminars. Members are not allowed to discuss what happens in the tomb with non-members, which is the source of the secrecy mythology. The actual content is widely understood from former members: each member gives a long autobiographical talk — a "life history" or "bio" — over the course of the year, covering childhood, family, religion, sexuality, ambition, fear, and major events. Other members listen, ask questions, respond. It is a structured form of confessional friendship.

Tap Day

Senior society selection happens on a single afternoon and evening in late April, traditionally the Thursday before reading week. The afternoon is informally called Tap Day and is one of the more peculiar Yale rituals to observe.

The mechanics, since the 1953 reform, are roughly as follows. Each society has had several months to identify the rising seniors it wants and arrives at Tap Day with a ranked list. In the early afternoon, current senior members fan out through the campus looking for the rising junior they have decided to tap. The senior touches the junior on the shoulder — the literal "tap" — names the society, and asks whether they accept. The junior says yes or no on the spot. If the junior declines, the senior moves down the ranked list. By late evening most societies have completed their tapping.

There is no public ceremony. Tapping happens in residential college courtyards, dining halls, dorm rooms, on the sidewalk on Old Campus. It is visible if you know what you are looking for and invisible if you do not. The striking feature of Tap Day for anybody who has spent four years at Yale is the gap between the cultural weight the day carries — for a century one of the dominant rituals of the senior year — and the actual physical event, which is a series of brief private conversations spread across an afternoon.

Until the early twentieth century the ritual was much more public. The original Tap Day, held annually in the Old Campus quadrangle from roughly 1880 until 1953, gathered the entire junior class in the courtyard at four in the afternoon while the seniors walked through the crowd looking for the men they intended to tap. The dramatic moment was the public touch on the shoulder in front of hundreds of watching juniors. The 1880–1953 version was painful for the three-quarters of the class who watched their classmates be tapped while they themselves were not. By the early 1950s pressure from undergraduate opinion and the deans had forced the ritual indoors, where it has stayed.

What Actually Happens in the Tombs

The popular imagination treats the tomb houses as venues for arcane ritual — robed figures, chanted oaths, perhaps actual skulls. The more accurate description is that they are dining clubs with seminar rooms attached. A typical evening at one of the older tombs runs roughly as follows.

The fifteen members arrive around seven-thirty. Cocktails are served in a front parlor; heavy drinking is discouraged because the evening requires sustained attention. Around eight the group sits down to dinner, prepared by non-member kitchen staff and served in a private dining room — two or three courses, two hours of conversation. After dinner the group moves to a different room where the formal program begins.

The program is the substantive part of the evening. Each member gives a sequence of three or four major bios over the course of the year, one per evening. Bios are typically thirty to forty-five minutes long and cover a defined topic: childhood, family, religious experience, sexuality, ambition, fear, formative reading. The most rigorous societies require each member to deliver four full life-history talks, roughly eight to ten hours of personal disclosure per member.

After the bio is delivered the other members ask questions, and in some societies every other member responds with their own reaction. The whole evening typically runs to eleven or midnight. Twice a week for thirty weeks, this happens. By the end of the year each member has heard fourteen other people's full autobiographies and has delivered their own four times. The intimacy is structural: there is no way to be in the room for thirty weeks and not know the other fourteen people more deeply than you know almost anybody else from college.

The physical interiors vary. Skull and Bones has the most genuinely strange interior — multiple themed rooms, a substantial library, formal portraits of past members. Scroll and Key has an Egyptian Revival main hall. Wolf's Head feels more like an old men's club in central London. Newer societies often occupy ordinary New Haven townhouses converted to society use.

What the Selection Actually Selects For

The mythology says the selection is dominated by family connection and prep-school networks. The historical reality is more mixed. The senior societies have been tapping public-school students since at least the 1920s, non-Anglo students since the 1930s and 1940s, women since 1991 (when Skull and Bones admitted women after a long internal fight), and international students actively for the last forty years.

What the selection actually emphasizes is harder to summarize. The seniors selecting next year's class are looking for fifteen people who can sustain four hours of interesting conversation a week for thirty weeks while telling each other the truth about their lives. This requires students who have something to say and can listen. It also requires variance — academic field, geographic origin, ethnic and religious background, artistic versus athletic versus political profile. A group of fifteen students who are too similar to each other will not produce a productive year.

International students are tapped with some frequency; the proportion in the senior society system roughly matches the 11–13% proportion in the senior class. The selection process is not, however, easy for international students to navigate. The dominant social currency for being visible to senior society talent scouts is participation in residential colleges, undergraduate organizations, athletic teams, publications — the same activities that produce visibility in any American college, but operating in English at full native fluency. Students who integrate quickly are routinely tapped; students who remain inside their own national or linguistic community are less often tapped, not because of bias but because the seniors do not see them.

The honest summary is that senior society membership for international students is achievable but not automatic, requires the same social investment any American student makes, and is one path among several for the kind of intra-Yale connection Yale exists partly to produce.

The Wall Street and DC Question

The most-asked question about senior societies, particularly from international students considering whether to invest the time, is whether membership confers a measurable career advantage. The honest answer is mixed.

For finance and consulting careers, the senior society network is real but secondary. The Yale alumni network is strong; the senior society subset is more concentrated and produces higher response rates to outreach. A Yale graduate cold-emailing a managing director will sometimes get a response; one cold-emailing a managing director from the same senior society almost always does. The marginal value is real but should not be overstated — Yale's general network is large enough that most graduates can find the introductions they need.

For DC careers — government, foreign service, intelligence — the senior society network has been historically dense. Skull and Bones in particular produced a remarkable concentration of senior US government figures during the early-to-mid twentieth century, including Henry Stimson (Secretary of War), Robert Lovett (Secretary of Defense), W. Averell Harriman (Ambassador to the Soviet Union), McGeorge Bundy (National Security Advisor), and several CIA directors. The pipeline has weakened since 2000 as federal hiring has become more credential-driven and the societies themselves more diverse in career outcome. A current Skull and Bones tap is not a guaranteed pathway to government service in 2026 the way it was in 1956.

For most career outcomes outside finance and DC, the senior society network is not particularly differentiated from the broader Yale alumni network. The career-ladder mythology is most active among people who have not actually been in a senior society. Members are roughly as careerist as the rest of the senior class, but the senior society dinner is not, in 2026, primarily a job-networking venue.

Why It Persists

The senior society system is an oddity. Most major American universities have nothing comparable. Harvard has its final clubs, but they operate on a different logic — they are predominantly social and bibulous rather than confessional, and the membership culture is different. Princeton has its eating clubs, which are larger, more open, and far more central to campus social life. Stanford and the Ivies west of the Hudson have nothing like Yale's tomb-house structure. The Yale system is genuinely unusual, and it has persisted for nearly two centuries despite multiple periods of campus opposition, reform, and predicted decline.

It persists, on the most charitable reading, because it produces something that the rest of Yale does not. The undergraduate curriculum at Yale is rigorous but predominantly individual — students take courses, write papers, sit for exams, accumulate honors. The residential college system is communal but loose — students share dining halls and dormitories with hundreds of other students they may or may not know well. The senior society system, by contrast, produces a small group of fifteen near-strangers who are required, by the structure of the tomb house's twice-a-week dinner schedule, to know each other's lives in detail by graduation. There is no obvious substitute for this experience inside the standard American college curriculum, and the four years of college do not otherwise produce many fifteen-person groups of acquaintances who become close friends through structured weekly disclosure.

For international students walking past 64 High Street or 444 College Street and wondering what happens inside, the answer is more banal than the buildings suggest and more substantive than the conspiracy theories indicate. People have dinner together. They tell each other about their lives. They argue. They listen. They form ties that, in some cases, last the next sixty years. The buildings are blank-walled brownstone tombs because the work inside requires the rest of the world to be visibly absent for those four hours twice a week. That is, on inspection, a more interesting purpose than a windowless building usually serves on an Ivy League campus.
