Mentoring and Coaching in the Workplace: A Practitioner’s Guide

Consider a new team lead who, until last month, was the strongest engineer on her team. She knows the product better than anyone. What she does not know yet is how budget requests move through her new peer group, which director to brief before a planning meeting, and how to tell a former teammate that his work is late without losing his trust.

The first two gaps are knowledge about this organization. A colleague who has been there for years can close them in a few conversations. The third is a skill. Advice will not build it. She has to try it, see what happens and adjust. That split, between knowledge someone can hand over and capability a person has to build, is the most practical way I know to choose between mentoring and coaching at work.

This guide shows how to apply that test to one person, what the research says about each approach, and how to start a workplace mentoring program whose mentors use coaching skills.

What Is Mentoring and Coaching in the Workplace?

Coaching and mentoring both support professional growth, but they work differently and serve different purposes.

Mentoring pairs a more experienced professional with a less experienced colleague. The mentor shares knowledge, perspective, and institutional wisdom built over years in the field or the organization. A senior sales director might mentor a high-potential manager on reading organizational politics, building executive relationships, and preparing for leadership roles. The focus is long-term career development through an ongoing relationship.

Coaching targets specific capabilities through structured, time-bound engagements. The International Coaching Federation (ICF) defines coaching as partnering with clients in a thought-provoking and creative process that inspires them to maximize their personal and professional potential. An executive coach might work with a director to strengthen strategic thinking (our executive coaching guide explains how), increase influence with cross-functional partners, or prepare for a general management role.

The distinction matters because it decides what kind of support helps someone move forward, and what kind wastes their time.

Two related terms mean something different, and it helps to keep them apart. ICF mentor coaching is the feedback a coach receives on recorded coaching sessions on the way to an ICF credential, and our article on what makes a good mentor coach explains how that role differs from a workplace mentor. Coaching supervision is reflective support for practicing coaches, and coaching, mentoring and supervision compared sets the three side by side. This article is about employees and the colleagues or coaches who help them develop.

Difference Between Coaching and Mentoring

Jonathan Passmore’s 2007 paper in the International Journal of Evidence Based Coaching and Mentoring compares the two on seven dimensions drawn from the coaching and mentoring literature. His table, summarized:

Passmore’s own conclusion is that the line between the two is blurrier than a table makes it look. He argues that coachees value behaviors more often associated with mentoring, such as sector knowledge and an understanding of leadership dilemmas, and he challenges the common claim that a coach’s distance from business knowledge is what gives coaching its independent perspective.

In practice, the clearest difference is what each person brings into the conversation and who decides what happens next. A coach brings process: questions, observation, structure, and the discipline to leave the decision with the client. A mentor brings content: what they have seen work in this organization or this field. A skilled mentor hands that content over in a way that still leaves the choice with the mentee. “In a similar situation, here’s what worked for me. What might you use from that?” is mentoring with a coaching stance. “When this happens, do that” is an instruction.

The ICF moved the line again in 2025. Its updated Core Competencies, released in September 2025, revised item 7.11 so that a coach “shares observations, knowledge, and feelings, without attachment, that have the potential to create new insights for the client.” The 2019 wording of that item spoke of observations, insights and feelings, with no mention of knowledge. A coach may now offer what they know, as long as they hold it loosely, and a good mentor already works that way. Our overview of what changed in the 2025 ICF Core Competencies covers the rest of the update.

When to Choose Coaching vs. Mentoring

Start with the gap. Ask what the person is missing, and whether someone else already has it to give.

When Mentoring Is the Right Call

Mentoring fits when the gap is knowledge another person already holds. Who to brief before a budget meeting. Which committee decisions stick. How the CEO makes decisions. A colleague who has spent years inside the organization can pass this on in conversation, and a training course cannot, because the knowledge is local. Mentoring also fits when someone wants career perspective from a person who has walked the path they are considering.

When Coaching Is the Right Call

Coaching fits when the gap is a capability that only practice builds: delegating, giving hard feedback, holding a position with peers, thinking at a larger scale. A director who struggles with executive presence already recognizes it in others, so telling her what it looks like adds little. She needs to try new behavior in real meetings, notice what happens and adjust, with someone helping her see what she is doing. A structured coaching engagement gives her agreed goals, regular sessions and a clear focus for what she will practice in her own work between them.

When You Need Both

A move up a level usually needs both. A manager stepping into a senior role has to build the capabilities the role demands, such as influencing without authority or thinking two levels up, and learn the politics of a level she has only seen from below. Coaching serves the first need. A mentor who already works at that level serves the second. Career transitions into a new function follow the same pattern.

One more test sharpens the call. Blanchard’s SLII, the later version of the situational leadership model, asks a leader to judge competence and commitment for each goal or task rather than for the person as a whole. Applied to development, that means proficiency here, in this organization. An executive hired from outside may be expert in her profession and a beginner in how things work here, with high motivation. Her first gaps are mostly knowledge of people and process, which points to a mentor. As she learns the organization, her motivation can waver while the remaining gaps turn into capabilities, and those transitions are a good signal to add a coach.

Coach, Mentor, or Both? A Five-Question Check

Use these questions for one person and one goal at a time. If the answers split, that is useful information too.

A clear majority in one direction settles it. A split usually means the person needs both. Keep the two roles with different people where you can. When one person does both, agree out loud which conversation you are having: sharing experience is mentoring, and helping the other person think a problem through without offering answers is coaching.

Examples of Coaching and Mentoring in the Workplace

Each example below serves one of the gaps above.

Reverse mentoring for a knowledge gap at the top. In a 2022 Mastercard Newsroom perspective on reverse mentoring, Safdar Khan describes pairing a younger employee with a seasoned one so the younger person can mentor the senior colleague on new trends and technologies. The senior leader learns what younger employees and customers want. The younger mentor builds confidence and leadership skills. Khan also warns that making the program mandatory can defeat its purpose.

Structured early-career mentoring for career perspective. Deloitte Middle East’s D-180 Digital Mentoring program pairs students and graduates in their first years of work with Deloitte volunteer professionals. It runs for 180 days, with about two to four hours of virtual meetings a month, and helps mentees explore the working world and set educational or career goals. A fixed length and a stated monthly commitment tell both sides exactly what they are agreeing to.

Coaching for a capability gap. Consider, as an illustration, a newly promoted director whose peers keep reopening decisions she thought were settled. She knows the business and has watched senior colleagues hold a line. A mentor could tell her how they do it. Coaching works on how she does it: what she says in the meeting, what she avoids saying, and what she will try in the next one. Over a series of sessions she sets the goal, tries a different approach with her peers, and reviews what changed.

The pattern across all three: mentoring moves knowledge or perspective from one person to another, and coaching builds a capability the person already understands but cannot yet use consistently.

Advice can close a knowledge gap. Only practice closes a skill gap.

What the Research Says About Mentoring and Coaching

Both approaches have support from meta-analyses, studies that pool many earlier studies. Both also have limits that matter when you promise results to a leadership team.

Mentoring. Allen and colleagues (2004), writing in the Journal of Applied Psychology, pooled the research on career benefits for people who are mentored. They found the results “generally supportive of the benefits associated with mentoring, but effect sizes associated with objective outcomes were small.” Objective outcomes here means measures such as compensation, and subjective outcomes include career satisfaction. Results also differed with the kind of mentoring provided, career-focused or psychosocial. The safer promise for a mentoring program is the subjective side, such as career satisfaction, rather than faster pay or promotion.

Coaching. Jones, Woods and Guillaume (2016), in the Journal of Occupational and Organizational Psychology, combined 17 studies of workplace coaching by internal or external coaches. They excluded coaching by a person’s own manager and peer coaching. Coaching had positive effects on organizational outcomes overall. Effects were stronger for internal coaches than for external ones, and they did not differ by format (face-to-face, or face-to-face blended with online coaching) or by the number of sessions or length of the engagement.

Two cautions follow. Neither study tells you which approach a particular person needs, so the gap test still does that work. And the finding on length is a reason to set the length of an engagement by its goal. It does not show that a short engagement will work for everyone. Both approaches belong in a leadership development plan as separate tools with separate jobs.

The Mentor’s Coaching Stance: What It Sounds Like

A mentor’s content is experience. The coaching stance is how that experience gets handed over so the mentee can use it. Without it, mentoring turns into information transfer: “when this happens, do that.” The mentee nods, leaves, and the advice does not stick, because the mentee never did the thinking. Six habits make the difference.

Listen Before You Answer

Let the mentee finish. Summarize what you heard before you respond, and check that you have it right. Leave room after a question. Silence is where people think, and filling it with advice ends the thinking.

Silence is where people think, and filling it with advice ends the thinking.

Ask Before You Tell

Find out what the mentee has already tried and what they think is going on. Open questions do this better than closed ones. “Did that presentation go well?” invites a yes or no. “What did you learn from giving that presentation?” invites reflection.

Offer Experience as One Option

This is the move that separates mentoring from instruction. Describe what you did in a similar situation and what happened, then hand it back: “Which part of that fits your situation, and which doesn’t?” The mentee decides what to use. Your experience stays one input among several, which is also the spirit of the 2025 ICF wording for coaches.

Give Feedback That Invites Reflection

Coaching feedback follows a simple sequence: ask permission, share a specific observation, describe its possible impact, and ask for the other person’s view. “Can I share something I noticed? You checked your phone during the team presentations. What do you think the room took from that?” It treats the mentee as a capable adult who can draw the conclusion.

Build Trust First

Trust is the foundation of any development relationship. Keep confidences. Do what you said you would do. Admit when you don’t know something. Share a relevant mistake of your own when it helps the mentee see the situation more clearly.

Use GROW to Structure a Conversation

GROW (Goal, Reality, Options, Will) is a simple frame for a development conversation and one of several frameworks for structuring coaching conversations. It works for mentors too. Its value comes from the quality of the questions at each stage. “What’s your goal?” gets a surface answer. “If we fast-forward six months and this has gone well, what’s different about how you show up in meetings?” gets somewhere useful.

How to Start a Workplace Mentoring Program That Uses Coaching Skills

Workplace mentoring programs need a clear purpose, willing participants, and mentors who know how to hand experience over. Six steps cover it.

1. Decide What the Program Is For

Name the gap it closes. Bringing senior hires up to speed on how things work here, giving early-career staff a view of possible paths, connecting senior leaders with what younger employees know, and preparing people for a move up a level are four different programs. Pick one purpose per cohort and design for it.

2. Make It Voluntary and Match on Purpose

Both people should want to take part. The Mastercard perspective above makes the same point about reverse mentoring: a mandatory program can defeat its purpose. Match mentors and mentees on the gap the mentee wants to close and the experience the mentor has, rather than on seniority alone.

3. Train Mentors in a Coaching Stance Before the First Meeting

Experienced managers and leaders do not automatically know how to pass experience on. A short training in coaching skills gives mentors the habits described above: listening, open questions, offering experience as an option, and feedback that invites reflection. Without it, mentors default to telling.

4. Contract Each Pair

Agree up front how often the pair will meet and for how long, what stays confidential, what the mentee wants from the relationship, and how either person can end it without awkwardness. The D-180 model, 180 days at two to four hours a month, shows how a fixed term makes the commitment concrete.

5. Know When to Bring In a Coach

Some gaps are capabilities a mentor cannot build for someone, however good the advice. Send those to coaching. Jones, Woods and Guillaume found stronger effects for internal coaches than external ones, so trained internal coaches are a real option. For senior leaders, or when an internal coach would sit too close to the politics, an external executive coach brings independence.

6. Measure What the Program Is For, and Recognize the Work

Measure against the purpose you named in step one: retention of senior hires, internal moves, or how participants rate the help they received. Given the small effects on pay and promotion in the mentoring research, avoid promising those. Mentoring takes real time from the people who do it, so include it in performance reviews and say publicly who is developing the next generation of leaders. When senior leaders cancel their own development sessions whenever things get busy, everyone learns that development is optional.
