PwC US to certify more than 85,000 staff in critical thinking and judgment

Most senior professionals can point to the file that taught them to be sceptical. It was usually unglamorous: a reconciliation that refused to reconcile, a memo resting on a figure nobody had checked, a partner asking the one question the analysis could not answer. Professional services firms have long relied on this apprenticeship model, in which juniors learn judgment by grinding through foundational work and getting it wrong in front of someone who cares. Generative AI now does a great deal of that foundational work, quickly and with considerable confidence. If the grind disappears, something has to replace what the grind used to teach.

That is the problem PwC US is now trying to solve at scale. Yolanda Seals-Coffield, Chief People and Inclusion Officer at PwC US, points out that professionals have traditionally built judgment by doing the work itself, researching, questioning assumptions and learning from mistakes. "As AI takes on more of these foundational tasks, it's changing how people develop the critical thinking and judgment skills that remain essential to quality work and trust," she writes. The firm's response is a Critical Thinking and Judgment certificate program for more than 85,000 partners and employees, rolling out from December 2026 across its US, Mexico and Acceleration Centers offices, with completion targeted by June 2027.

What the program involves

The program is built on PwC's proprietary Critical Thinking and Judgment Framework, which is being validated with input from professors affiliated with the Wharton School and Harvard University. Participants begin with a diagnostic scenario that shows them their thinking preferences, strengths and opportunities for growth. They then learn the framework and apply it to practical situations, supported by masterclass videos featuring PwC leaders and external thought leaders. Personalised simulations relevant to each person's work follow, along with toolkits for use on the job, team collaboration scenarios and practical routines. The stated aim is a practical and repeatable way of evaluating information, challenging assumptions and exercising sound judgment, particularly when AI is involved.

Margaret Burke, PwC US talent acquisition and development leader, has described an exercise that makes the intent concrete. A tax professional reviews an AI generated analysis of a complicated tax position. Even if the recommendation looks convincing, the supporting information may be incomplete, so before deciding they verify sources, consider alternative interpretations and work out what further evidence is needed. "It's an opportunity to practice the judgment involved in making a decision, rather than simply learning about critical thinking in theory," Burke says. She has also said PwC intends to introduce an AI coach trained on its framework to help employees practise during their actual work.

Why universities are part of it

From early 2027 PwC will make the framework available to any university and fund selected universities to help professors build materials for introductory courses. This Student Human Skills Initiative extends the firm's existing Human Skills Project. Reported estimates put the investment at more than US$100 million across the programme and related university support, a figure that covers development and university funding rather than the certification alone. The logic is easy to follow. If graduates arrive having never done the routine work that once trained their scepticism, a firm either teaches judgment explicitly or inherits people who accept a fluent answer simply because it is fluent.

What this means for L&D

The design choices matter more than the headcount. PwC starts with a diagnostic rather than a lecture, so people see how they actually think before being told how they should. It anchors practice in scenarios that resemble real client work, where the AI output is plausible and the flaw is buried in the evidence. It also plans to carry the method into the workday through routines, toolkits and a coach, which is where most training programmes quietly fall apart.

Few organisations will build a proprietary framework and validate it with academics, but almost all of them need a shared language for questioning machine output before it reaches a customer, an auditor or a board. That shared language is the gap our Critical Thinking program is designed to fill, and it is the piece that has to exist before any tooling or coaching can reinforce it. Leaders running AI rollouts should ask where their people used to learn judgment and whether that work is still being done by humans. If it is not, the budget for AI tools needs a matching line for the skill of doubting them.
