Fields Medal Winners Are Not Assessed by KPIs—Can Law Firms' Quantitative Assessments Really Identify Good Lawyers? 2026 Legal Observations on the Evaluation Mechanism of the Legal Profession
On July 23, 2026, at the opening ceremony of the International Congress of Mathematicians in Philadelphia, USA, Chinese mathematician Wang Hong received the Fields Medal from the president of the International Mathematical Union, with University of Chicago professor Deng Yu sharing the stage as a fellow laureate. This is the first time since the Fields Medal was established in 1936 that a Chinese mathematician has appeared on the list of winners. Public discussion quickly turned to the Institut des Hautes Études Scientifiques in France, where Wang Hong works—an institution that has appointed only 14 permanent professors in its 68-year history, 9 of whom later won the Fields Medal, and which has no paper-based KPI system and no teaching or administrative duties.
For the legal profession, the value of this sample lies not in proving that "eliminating quantification will produce top-tier results," but in helping us see the applicable boundaries of an evaluation system. How law firm assessments should balance commercial efficiency and deep professional cultivation, and how much room should be reserved for "slow but deep" growth, is not only a management issue but also involves the institutional design of lawyer practice evaluation under laws and regulations such as the Lawyers Law and the Measures for the Administration of Law Firms.
Legal Basis and Boundaries of Quantitative Assessment in Law Firms
Domestic lawyers generally face a dual assessment system: one set consists of internal performance metrics set by law firms based on commercial operations, serving profit distribution and rank promotion; the other is the industry regulatory assessment conducted by judicial administrative authorities and bar associations, directly tied to practice qualifications.
From the perspective of industry regulation, Article 46 of the Lawyers Law stipulates that bar associations shall perform duties such as "organizing professional training for lawyers" and "assessing lawyers' practice activities." Article 56 of the Measures for the Administration of Law Firms also clearly provides that law firms shall establish an annual assessment system for lawyers' practice, assessing their practice performance, professional ethics, and practice discipline. This means that a law firm's internal assessment is not merely a commercial management activity but also carries the statutory function of implementing industry regulatory requirements.
However, the law does not stipulate the specific forms of assessment. Billable hours, revenue generation, and the point system constitute the three mainstream evaluation dimensions in domestic law firms. The billable hours system originated in the United States in the early 20th century, anchoring lawyers' work input through recordable time; the revenue generation system emphasizes "more pay for more work" and "case sources above all"; the point system originates from the lockstep system of Anglo-American law firms, distributing profits based on seniority. Each of these three models carries its own legal risks: the billable hours system may trigger overtime pay disputes, the revenue generation system may lead to failures in conflict-of-interest reviews, and the point system may touch upon compliance issues in partner equity distribution.
In 2021, the Ministry of Justice and the All China Lawyers Association issued the Opinions on Further Regulating Lawyers' Service Fees, emphasizing that law firms should establish a scientific and reasonable lawyer compensation system and must not use revenue generation alone as the sole criterion for lawyers' rank promotion. This provision set a bottom line for law firm assessments: quantitative indicators may be used for reference, but they cannot become the only yardstick.
Labor law risks behind working hours and revenue generation assessments.
The legal risks of working hour systems in law firm management are often overlooked. According to Article 31 of the Labor Contract Law, employers shall strictly implement labor quota standards and shall not force or disguisedly force workers to work overtime. When a law firm sets minimum billable hour targets, if linked to compensation distribution and promotion, it may be deemed as disguised forced overtime. In 2023, a law firm in Beijing was found by a labor arbitration institution to have engaged in disguised forced overtime because it required salaried lawyers to have a minimum of no less than 180 billable hours per month, and the firm was ordered to pay the difference in overtime pay.
The revenue-generation system involves more complex legal issues. Article 23 of the Lawyers Law stipulates that law firms shall establish and improve systems for practice management, conflict-of-interest review, and fee collection and financial management. When a law firm places excessive emphasis on individual revenue generation, lawyers may neglect conflict-of-interest reviews in order to meet targets. In 2024, a law firm in Shanghai was imposed an administrative penalty of a three-month suspension of business for rectification by the judicial administrative authority because it failed to strictly review a conflict of interest and represented both parties in the same case.
Cheng Yang, a member of the management committee at Lantai Law Firm, said during a research interview that at the partner level, Lantai's core assessment metric is "revenue plus quality-efficiency ratio." The quality-efficiency ratio is used to constrain the operational resources consumed behind business engagements, preventing partners from taking on large volumes of low-yield work that drains team manpower. This design essentially seeks a balance between commercial efficiency and practice compliance.
Key Legal Compliance Points for Point Systems and Partner Equity Distribution
The point system originated from the point-based system used by British and American law firms. A pure point system uses only partner seniority as the criterion: the deeper the seniority, the higher the points, and the greater the profit share. This mechanism helps encourage teamwork, but it may also trigger disputes over partners' rights and interests.
Article 18 of the Partnership Enterprise Law stipulates that a partnership agreement shall specify the profit distribution method. If a law firm adopts a point system for profit distribution, the partnership agreement must clearly define the point calculation standards, adjustment mechanisms, and dispute resolution methods. In 2025, a law firm in Shenzhen, because its partnership agreement did not clearly specify point adjustment rules, had a dispute between two senior partners over adjusting points from 12 to 10, which ultimately led to litigation. The court, in accordance with Article 33 of the Partnership Enterprise Law, ruled that distribution should be based on the partnership agreement or the proportion of actual capital contributions, and because the agreement was unclear, rejected the law firm's unilateral decision to adjust the points.
Lawyer Chen Jie has observed a phenomenon in the industry that merits reflection: some young partners show outstanding revenue figures on paper, but their case resources do not entirely stem from the accumulation of their own professional capabilities. When faced with such candidates, law firms will not grant promotion to senior partner based solely on revenue figures; years of practice, professional strength, and reputation within the industry also serve as important factors to be weighed. This practice is consistent with the practice requirements of the Lawyers Law for lawyers to "safeguard the lawful rights and interests of parties, safeguard the correct implementation of the law, and safeguard social fairness and justice."
Legal Recommendations for Optimizing the Lawyer Evaluation Mechanism
For law firms, the design of the assessment mechanism should follow three legal principles: first, the principle of legality—assessment standards must not violate the mandatory provisions of laws and regulations such as the Labor Law, the Labor Contract Law, and the Lawyers Law; second, the principle of reasonableness—assessment indicators should match lawyers' practice stages and areas of specialization; third, the principle of procedural due process—the formulation and amendment of assessment rules should go through the democratic procedures of a partners' meeting or a lawyers' general meeting.
For individual lawyers facing unreasonable assessment metrics, they can defend their rights through the following channels: if it involves a dispute over labor remuneration, they may apply for labor arbitration in accordance with the Labor Contract Law; if it involves a dispute over the rights and interests of partners, they may file a lawsuit in accordance with the Partnership Enterprise Law; if it involves a dispute over industry regulatory assessment, they may apply to the lawyers association for a review.
Industry managers should learn from the IHES experience and recognize that quantitative assessment has clear boundaries of applicability. For highly specialized work with long result cycles, aggressive short-cycle quantification can instead undermine long-term value. It is recommended to increase the weight of soft indicators such as professional accumulation, talent development, and contributions to the public good of the industry in the lawyer evaluation system, so as to leave room for "slow but deep" growth.
Guangdong Zhiming Law Firm has long focused on the governance of the legal profession and practice compliance, providing law firms with specialized legal services such as assessment system design, partnership agreement review, and labor and employment compliance. Under the legal framework of reforming the lawyer evaluation mechanism, helping law firms establish an assessment system that both aligns with business logic and upholds legal bottom lines is a core value that professional lawyers can provide.
