The Assignment System

The cornerstone of professional development at Simpson Thacher is our assignment system.

It is designed to accomplish four imperatives:
  • Expose associates to the broadest array of areas within their practice group
  • Ensure that associates develop the widest range of critical skills
  • Foster a true spirit of teamwork
  • Mitigate the possibility that any associate ends up in a personally or professionally untenable position

New associates join one of seven departments: CorporateLitigation (our two largest), Executive Compensation & Employee Benefits, Exempt Organizations, Personal Planning, Real Estate or Tax. Associates make this selection based on their interest and career development goals. Whenever possible, we aim to help associates explore the many avenues available to them at the Firm to help develop their skills and advance their professional development.

Our Assigning Partners along with our Professional Development Managers in each department are central to the assigning system. They are responsible for ensuring that every associate receives a workload of significant breadth and opportunity for skill development. Assigning Partners and Professional Development Managers check in regularly to ensure that workloads are fair and an associate’s time is not unduly monopolized. It is a critical role played by dedicated people.
“It’s a surprisingly thoughtful process, as the partners take the time to think about why they are giving you something, plus centralized staffing takes the pressure off juniors!”
- Chambers quoting a Simpson Associate

The assigning systems work well, in part, because of frequent opportunities for feedback. Each department uses open channels of communication with associates to make certain that assignments run smoothly. In short, you are not on our own – instead, you are part of a group with a staffing team whose job is to make sure your workload and experience are properly managed.


The hallmark of our New York Corporate Department is our rotation system. By working in multiple areas, we believe associates develop a deep understanding of the extensive work we do and the importance of teamwork across practices.

The Corporate Department is divided into the following subgroups: Banking and Credit (which includes Project Finance and Restructuring and Bankruptcy); Capital Markets; Mergers and Acquisitions; and Private and Registered Funds. In addition to these subgroups, the Firm also offers associates an opportunity to rotate into additional practices, specifically Real Estate or Executive Compensation & Employee Benefits.  Instead of choosing a practice area on day one, corporate associates may elect to rotate through two sub-groups for approximately 18 months in total.  This provides immediate exposure to different transnational practices before becoming immersed in a permanent space.  Associates also select a "Back-up" practice group during both rotations.  This provides opportunities for exposure to additional practice areas as workflow permits. 

In our "Advisor Program", our newest corporate associates are paired with a partner for the first three months of each rotation to accelerate development.  The Advisor program encourages intensive training and a close working relationship with a partner from the very start.  


Professional development and individual preference are the key drivers in the Litigation Department’s assigning process. Our practice is remarkably varied. These aren’t formal subgroups, though, and there are no required rotations. Therefore the Litigation Department strives to assign a range of matters to all associates while allowing them in due course to bore into one or two practice areas as they become more senior.

New litigators are typically given several assignments, each in a different area—a securities matter, an antitrust matter and a government investigation matter would be a good example of initial assignments. Associates also are encouraged to take on a pro bono matter of their choice. The cross-disciplinary nature of our department ensures regular exposure to many practice areas, as well as opportunities to work with lawyers across the Firm.

Our Litigation Department includes subpractices in Securities LitigationAntitrust & Competition, Government and Internal Investigations, Insurance, Intellectual Property, and International Arbitration.

The assignment system within our five specialty departments—Executive Compensation and Employee Benefits, Exempt Organizations, Personal Planning, Real Estate and Tax—reflects the Firm’s commitment to training lawyers in a broad and deep set of professional skills. Since these departments are smaller than Corporate and Litigation, we use a less formal assignment system while accommodating individual preferences when assigning work.

Each of these departments has developed its own way of leveraging the opportunity that flows from a smaller scale. For example:

  • Tax associates are informally paired with a partner for up to a year, although such pairings are more loosely organized than a formal mentoring program. Associates don’t work exclusively with the partner, but the partner is available to answer questions and provide continuity.
  • Real Estate is a close-knit group in which junior associates work side-by-side with senior associates and partners from the outset. Group lunches in Real Estate allow everyone to communicate regularly and discuss topical issues.
  • New Executive Compensation and Employee Benefits lawyers typically “shadow” a mid-level or senior associate for their first month at the Firm. The group also has lunch seminars at least every two weeks to review skills and practice particulars.

In each department, these are idiosyncratic systems that work incredibly well. These departments illustrate the attributes of Simpson Thacher’s exquisitely balanced culture and associates get the twin benefits of intimacy and scale.
