Most board evaluations are judged by the report at the end. The reading that actually decides whether the evaluation will hold is the one no one sees: how the board readied itself before the first interview. A board that skips preparation gets a survey; a board that prepares gets a decision-grade evaluation.
A board evaluation is one of the few moments a board reads itself. The reading it produces is only as useful as the preparation that sustains it. Boards that arrive at the evaluation without having decided what they want to know, how they will use the reading, and who owns the process end up with a report that gets filed. Boards that prepare the evaluation end up with a decision-grade instrument.
The fourth edition of Mexico's Code of Principles and Best Practices of Corporate Governance, published by the Business Coordinating Council (CCE) in February 2025 and in force since January 1, 2025 — the first revision since 2018 — recommends in its Best Practice 23 that boards periodically evaluate directors individually and the board as a body, and adds that at least once every four years the evaluation should be conducted by an external facilitator. The 4th edition is registered as the current Mexican governance framework in the OECD Corporate Governance Factbook 2025, Mexico country note. The cadence is already named. The operating question is what the board does with the months before the evaluation begins.
This reading is for the chair and the board's evaluation-and-compensation committee — the two actors the CCE Code's Best Practice 55, item 9, names as responsible for conducting the evaluation of the board and its directors. Six preparatory decisions determine whether a board evaluation will produce a reading the table can actually use, or a compliance exercise no one remembers six months later. Each decision should be named — and documented — before the first interview.
What is the board asking the evaluation to read?
The first preparatory decision is the one most often skipped: naming the mandate of the evaluation. A board can ask its evaluation to read very different things. It can ask it to read the effectiveness of collegial operation — how agendas are set, how materials arrive, how decisions are made, how disagreements get documented. It can ask it to read composition — whether the board holds the mix of experience, judgment, independence, and diversity the shareholder mandate requires. It can ask it to read individual director performance — what sustained contribution each seat brings to the table. It can ask it to read the board's relationship with the CEO — whether the board stewards without managing, and whether the CEO operates with appropriate autonomy. Or it can ask for all of the above at once.
Each reading requires a different method, a different question set, and a different duration. A board that does not name the mandate buys an instrument that covers everything superficially and answers nothing at the depth the board's next decision will require. A board that names the mandate — and prioritizes it — receives a reading it can use. The useful rule: a board evaluation should answer three or four questions the chair and the evaluation-and-compensation committee can articulate on one page, before the work begins.
What is the scope of the evaluation?
The second preparatory decision bounds the scope. A board evaluation can cover the full board only, or the full board and its committees (audit, corporate practices, evaluation and compensation, finance and planning), or the full board, the committees, and directors individually — the range the CCE Code's Best Practice 23 recognizes as legitimate. It can include the chair. It can include the corporate secretary. It can include the relationship with the external auditor. It may or may not include a read on the CEO for the year in question.
Every extension of scope costs board time, CEO time, and facilitator fees. An ambitious scope without a clear mandate produces a long report and a weak decision. A disciplined scope tied to the mandate produces a short report and a decision with density. The chair and the evaluation-and-compensation committee should agree the scope in writing — what is in, what is out, and why — before the facilitator is invited to propose.
On what cadence should this board be evaluated?
The third preparatory decision sets the cadence. The CCE Code's Best Practice 23 recommends periodic evaluation with external facilitation at least once every four years. The G20/OECD Principles of Corporate Governance 2023, section V.E.4, recommend that boards regularly carry out evaluations and note that many corporate governance codes recommend an annual evaluation, periodically supported by external facilitators to increase objectivity. The Mexican floor and the international reference are consistent: periodic cadence, with external facilitation at least every four years.
A useful cadence is rarely an annual decision repeated by habit. A mature board typically alternates between internal evaluations — light, focused, led by the chair or the evaluation-and-compensation committee — and deeper external evaluations every three or four years. The cadence should be tied to the board's institutional moments: a deep evaluation before renewing a majority of seats, before a CEO succession, before a material transaction, or after a significant change in the shareholder mandate. Evaluating for the sake of evaluating in a year without consequential decisions wears the table down and erodes the seriousness of the instrument.
Will an external facilitator conduct it, and who chooses the external?
The fourth preparatory decision determines whether the evaluation is conducted internally or with an external facilitator — and, if external, how the facilitator is chosen. The CCE Code names external facilitation as a periodic recommendation; the G20/OECD Principles name it as the mechanism that increases objectivity. When a board is going to read its own effectiveness, its own composition, or the chair's performance, external facilitation is not a luxury — it is what makes the reading defensible to shareholders and to the board's next decision.
Choosing the facilitator is an act of stewardship. Four criteria separate a serious facilitator from a survey vendor. One: the firm has a named method — not a template — and can explain how it reads a Mexican board specifically, not a generic one. Two: the senior practitioner who will lead the work is named in the proposal and will be present in the board interviews. Three: the firm is independent of the external auditor, of any executive-search firm that placed current directors, and of any other provider with an interest in the board's future composition. Four: the firm can say no — it can push back on questionnaire items that compromise the seriousness of the instrument, and it can recommend narrowing the scope when the mandate is too broad for the time allotted.
The evaluation-and-compensation committee runs the selection and brings the recommendation to the full board for approval. The engagement is documented with terms of reference, scope, timeline, ownership of information gathered, response-anonymity policy, and data destruction protocol at closing. This documentation protects the table in any subsequent dispute over what the evaluation did or did not read.
What questions will make the reading useful?
The fifth preparatory decision is the construction of the questionnaire. A generic questionnaire produces generic answers; a questionnaire tied to the mandate produces answers the table can use. Construction is a shared piece of work between the facilitator — who brings method discipline — and the chair with the evaluation-and-compensation committee — who bring specific knowledge of the decisions the board has faced and the decisions coming into view.
A useful questionnaire combines three registers. One closed, with calibrated items that allow comparability across directors and over time — without collapsing into numeric scales presented as verdict on a director. One open, with short questions that invite a director to name what the table is seeing well, what it is not seeing, and where the director's own contribution could be more useful. And one situational, with one or two real recent decisions of the board — recognizable but not named — that let the director expose judgment on the process of decision, not merely on the outcome.
Individual interviews are usually worth more than the written survey. A forty-five-minute interview with a director, conducted by a senior practitioner with judgment, produces material with a density no survey matches. Boards that privilege the written questionnaire over the interview tend to receive the report the questionnaire rewards. Boards that privilege the interview tend to receive the report the board itself needs to read.
How will the reading land in the boardroom?
The sixth preparatory decision — and the one most forgotten — names how the report will land. A board evaluation that ends with delivering a document to the chair is a half-finished evaluation. The reading only becomes decision if the board receives it, debates it, and agrees what it will do with it.
The landing sequence should be agreed in advance. First, the chair receives the report with the facilitator — typically two weeks before the full board meeting. Second, the chair shares individual findings with each director separately and in confidence. Third, the report on collegial operation is presented in the full board meeting, with the facilitator present, and a working session opens in which the board decides which recommendations to adopt, which to reject and why, and what commitments to make for the next cycle. Fourth, the evaluation-and-compensation committee stewards the follow-up over the year and reports in the session before the next evaluation.
Boards that do not design the landing typically lose half the value of the evaluation. Findings get filed, the individual conversation is not sustained, and next year the board starts from zero. Boards that do design the landing read the following year against the commitments of the current year — and that exercise, more than the report, is what sustains the discipline of evaluation over time.
How does board evaluation integrate with the adjacent readings?
A board evaluation does not live alone. It runs in the same institutional cadence as executive assessment, CEO succession readiness, and — in relevant years — the review of the shareholder mandate itself. A board that prepares its own evaluation well often discovers, in the process, what it is asking of the CEO seat and what it is asking of the external auditor's seat. That cross-reading is native to the method and should not surprise the chair.
The preparatory error to avoid is treating the board evaluation as an isolated event. The board evaluation practice inside the Anker Bioss advisory model is built on the opposite premise: the reading of the full board integrates with the reading of composition, the reading of the CEO seat, and — where relevant — the reading of the shareholder mandate. That integration is what turns the evaluation into a stewardship instrument rather than a compliance exercise.
A board that prepares well receives a board evaluation the table remembers a year later. A board that does not prepare receives a report the next board will repeat. The difference is decided before the facilitator walks into the room.
If your board is designing its next evaluation — the first external one, the four-year external update, or a deeper reading before an institutional decision — we can accompany the naming of the six preparatory decisions before the work begins.
Frequently asked questions
How often should a board be evaluated in Mexico? The CCE Code's Best Practice 23 (4th edition, in force January 1, 2025) recommends periodic evaluation, with external facilitation at least once every four years. In practice, mature boards alternate between light internal readings (annual or biennial) and a deeper external evaluation every three or four years, tied to institutional moments — seat renewals, CEO succession, material transactions.
Who owns the process inside the board? The CCE Code's Best Practice 55, item 9, assigns the evaluation of the board and its directors to the evaluation-and-compensation committee. In practice, the chair shares with that committee the responsibility to name the mandate, the scope, the choice of facilitator, and the landing of the report. The corporate secretary stewards the documentation.
How long does a well-prepared external evaluation take? A typical external engagement runs ten to sixteen weeks from contract signing: two to three weeks for mandate, scope, and questionnaire; four to six weeks for individual interviews and the written survey; two to three weeks for analysis and report; and two to four weeks for landing — the chair meeting, confidential individual conversations, presentation to the full board, and the working session. A facilitator promising a decision-grade report in four weeks is delivering a survey.
Can a family business board be evaluated with the same method as a listed company? The method is the same — mandate, scope, cadence, external facilitation, questionnaire, landing. The adjustments are on what the mandate reads: in a family business the board typically stewards the relationship between family, ownership, and management, and the evaluation should read explicitly how the board sustains that stewardship. The family principals and — where one exists — the family council are actors in the preparatory mandate, not readers of the final report.
