The other half of your talent strategy: Why accounting firms need intergenerational mentorship

Tania has been with your firm for 31 years. She knows which clients prefer a call over an email. She knows how to read an anxious business owner. She knows where the figurative bodies are buried in every set of financials she's touched since 1995. She’s got three decades of deep and accumulated institutional knowledge.

Tania is retiring in 18 months. Does your firm have a plan for what happens to everything she knows?

The accounting profession is experiencing a genuine pipeline crisis, but the conversation almost always centers on recruitment. The deeper threat is the knowledge that walks out the door with every retiring partner.

A crisis in two parts

Here are the numbers:

• The number of people sitting for the CPA exam has declined more than 30% since 2016.

• Accounting graduates hit a new 20-year low.

• CPA-credentialed roles now take an average of 73 days to fill, which is 41% longer than comparable positions without the designation.

At the same time as all of this, a generation of experienced partners is heading towards retirement.

Most talent strategies address the first part of this situation: the lack of new talent. But almost none of them address the second part.

Why recruiting harder won't be enough

The firms investing most heavily in recruiting today are solving a talent flow problem, rather than a depth problem.

You can hire a new graduate, sure. But you can’t buy a partner's three decades of client judgment. Firm leaders need to start pairing the “How do we get new talent through the door?” question with “How do we ensure that the knowledge people have when they leave doesn’t leave with them?”

This is where structured and deliberate intergenerational mentorship comes in. This is a formal type of mentorship. It’s a program that’s detailed and documented, designed to transfer specific knowledge, relationships, and judgment from one generation to the next.

Forget about the junior staff member merely looking over the shoulder of your senior partners. This means serious guidance.

In her piece for Accounting Today, Rachel Farris, CPA explains that “To truly retain young talent, firms need to reintroduce genuine mentorship and connection. This means creating relationships that help newer professionals connect their daily work to their long-term growth and see how it impacts the firm's success.”

Two problems, one solution

The CPA Journal's April 2026 analysis of the talent pipeline crisis argues for exactly this approach. It refers to it as a holistic, intergenerational human resources strategy that addresses both attraction and retention. And it benefits both sides of the equation.

Experienced partners and managers:

• Bring institutional knowledge about client history, firm culture, the judgment that only comes from time

• Are provided with a meaningful role in the firm’s legacy via a structured mentoring program

• Are provided with a pathway to transition that looks more like a planned offramp rather than a cliff edge

Newer staff:

• Bring fluency with current technology and AI tools, which senior staff can learn through collaboration

• Bring fresh perspectives on client service that experienced practitioners may not see

• Are more likely to stay because they are supported via a mentor

What this looks like in practice

Effective mentorship programs in professional services firms need to be structured, with carefully selected mentor-mentee pairings, scheduled touchpoints, documented goals, and accountability for outcomes on both sides. 

For example, a senior partner isn't just available for questions—they're accountable for introducing a mentee to three key clients over six months, or for co-leading a specific engagement.

The programs that work also measure concrete knowledge transfer. Can the mentee handle this client relationship independently in 12 months? Can the senior partner name three things they've learned about working differently from their mentee? 

The answers tell you whether the program is actually working.

Build it before you need it

The firms investing in intergenerational mentorship now have recognized that recruitment is only half the equation, and that the half they've been ignoring is the one that takes years to rebuild.
