BigLaw is the shorthand for the largest law firms in the United States — firms with hundreds of lawyers that hire new graduates in classes and pay the highest median starting salaries in private practice.
The scale is measurable: firms of more than 500 lawyers are the single largest employer of new law graduates, and about one in four employed Class of 2025 graduates began practice in BigLaw, counting firms of 251–500 lawyers too.
What counts as BigLaw?
"BigLaw" is industry shorthand for the largest law firms in the United States — firms with hundreds of lawyers and new-graduate hiring in classes rather than one hire at a time.
People draw the line in different places, so the useful approach is the data that research organizations publish about firm size and pay.
NALP, the association that researches legal recruiting, draws the line by headcount.
In its Class of 2025 data, firms of more than 500 lawyers were the single largest employer of new law graduates, taking more than one in five employed graduates; count firms of 251–500 lawyers too, and about one in four employed Class of 2025 graduates began practice in what NALP itself calls BigLaw.
The footprint is large: firms of 501+ lawyers accounted for 33.2% of all law firm jobs obtained by the Class of 2025.
The other end of the market looks different — firms of 1–10 lawyers accounted for 26.4%.
That two-ended shape is what a BigLaw-versus-small-firm career choice actually looks like in the data.
Pay marks the line as clearly as headcount does.
The Class of 2025 median private-practice starting salary was $155,000 — and firm size moved it sharply: medians ranged from $84,000 at firms of 1–10 lawyers to $225,000 at firms of more than 500 lawyers.
NALP describes new-lawyer salaries as bimodal — for the Class of 2024, 53.0% of reported salaries fell between $55,000 and $100,000, with a second peak at the prevailing BigLaw salary.
That second peak is the BigLaw peak in NALP's data.
You will also see the terms "Am Law 100" and "Am Law 200."
Those are commercial ranking labels, and our research did not verify the criteria behind them — so this page defines BigLaw by the two measures above, headcount and starting pay, rather than by ranking membership.
Shorthand, not a legal category
How BigLaw firms are structured: leverage, practice groups and partner tiers
Large firms organize their lawyers into practice groups — litigation, corporate and transactional work, regulatory, and more — and an associate joins a group rather than floating across all of them.
Work flows through those groups: partners hold the client relationships, and teams of associates staff the matters those relationships produce.
The arithmetic behind the arrangement is called leverage — the balance of associates to partners — and it is the engine of the model, because a wider associate bench means more billable work produced around each client relationship.
The partner tier itself is not one thing.
NALP tracks multi-tier firms — firms with more than one partner tier — and its data shows the equity share shrinking there: equity partners fell from 61.3% of all partners in 2011 to 56.3% in 2024.
The share is not even across groups, either — in 2024, nearly 60% of men partners at multi-tier firms were equity partners, versus 48% of women partners and 47% of partners of color.
Partnership is not the only senior path, either.
NALP tracks counsel and non-traditional-track staff attorneys as separate law-firm categories — lawyer roles outside the associate-to-partner ladder — and of counsel is its own firm title with its own conventions.
If you want the destination end of the ladder in detail, the law firm partner role is its own subject.
What associates do and how many hours they work
The associate job is an apprenticeship in firm form.
Associates research and draft — memos, briefs, contracts — run discovery and document review in litigation, and support due diligence in transactions.
Partners supervise the work and hold the client relationships.
The hours question is the one everyone asks, and the honest answer has two layers.
The first is what the data says about lawyers overall: BLS reports that most lawyers work full time and some work more than 40 hours a week.
The second layer is BigLaw-specific, and here the honest answer is that our research located no primary-source average for BigLaw billable hours — so treat any single "average associate bills X hours" figure you see as unverified.
What does exist is firm-level reporting from the 2026 salary season: market-scale firms that matched Milbank's raise have tied the scale to 1,900- or 2,000-hour billable expectations — Norton Rose Fulbright at 1,900 and McDermott and Quinn Emanuel at 2,000, with Milbank's own memo listing no number.
Those figures come from secondary reporting — an industry scorecard and reported firm memos — that our research could not verify against primary sources.
Read them as a picture of how the market ties pay to hours, not as a verified standard.
Billable targets are set firm by firm
Who BigLaw hires: summer associates, OCI and laterals
For law students, a summer-associate seat is the classic on-ramp: a 2L summer at the firm that converts to a post-graduation offer.
The conversion odds are remarkable — in 2025, the offer rate from 2L summer programs was 97%, with an 89.4% acceptance rate — and the programs are small: the average 2L summer class was eight associates per office in 2025, though New York City offices averaged 29.
Recruiting now reaches 1Ls too: 1L summer associates received offers to return for the 2L summer at a record 94.2% rate.
The on-campus interviewing (OCI) you may picture is no longer the main door.
In the 2025 recruiting cycle — for the 2026 2L summer programs — 80% of offers came from employer-sponsored recruiting, meaning direct application, and 20% came through law-school-sponsored methods such as OCI, per NALP's January 26, 2026 report.
Timing has moved earlier too: 85% of 2L summer offers in that cycle were made before July, and some law schools moved their traditional OCI programs to spring or early summer in 2025 as early interview programs (EIPs) spread.
One piece of recruiting folklore to discard: the idea that offers must stay open a fixed number of days.
NALP's current Principles for a Fair and Ethical Recruitment Process call for reasonable response deadlines and a reasonable time to consider offers — with no fixed day count.
The "28 days, or until December 30" rule you may see quoted online is not in the current Principles.
The other door is lateral hiring: lawyers already in practice move between firms as associates, counsel or partners, recruited directly rather than through campus cycles.
For students and new graduates, the numbers above are the practical takeaway — entry-level BigLaw hiring runs through a small number of summer seats, filled earlier in law school than the traditional timeline suggests, and mostly through direct applications rather than OCI.
Why associates leave BigLaw — and where they go
Start with the number everyone quotes, because it deserves caution.
NALP Foundation reports track associate attrition, but they are member-only, so no current verified rate is public.
Search results cite 26% for 2021 — a record year — and an 18% update in April 2024; our research could not confirm either figure against a primary source.
Treat any precise attrition percentage you encounter with that caveat attached.
The structural reasons are visible in the model itself.
The apprenticeship runs on the long hours described above, and the partnership ladder narrows as it rises — equity partners were 56.3% of all partners at multi-tier firms in 2024, down from 61.3% in 2011, so even reaching "partner" is not the same as reaching equity.
Where do associates go?
Destinations include in-house legal departments — in-house counsel work — government and public-interest practice, smaller firms, and business roles where a law degree is currency.
Each is a career with its own economics, and the move need not be a downgrade in substance; it is a trade of the scale premium for a different mix of hours, autonomy and work.
If you are planning a BigLaw run, plan the exit with the same care as the entry.
Treat each class year as a decision point rather than a default: the years on the scale build skills and savings, and lawyers who leave deliberately — toward a named destination, on a timeline they chose — get more from both sides of the move.
