Coaching vs mentoring: what's the difference, and when should a manager use each?
by Tony Gardner, 18 October 2026
Mentoring passes knowledge from the mentor to the mentee. Coaching sees the coach ask the coachee questions that require them to think for themselves: the answers come from the person being coached.
Both help people develop. Both are needed in the workplace and a part of leadership. The difference is who does the thinking.
What mentoring and coaching are
Both are one-to-one conversations aimed at someone's development. The CIPD, the UK professional body for HR and people development, describes mentoring as a more experienced colleague sharing their greater knowledge to support a less experienced person. The International Coaching Federation (ICF) describes a mentor as an expert who provides wisdom and guidance based on their own experience.
Coaching works differently. The CIPD calls it "essentially a non-directive form of development", and the ICF describes "a thought-provoking and creative process" that does not include advising. A coach doesn't need to know the answer. Their job is to help the other person find it.
The differences at a glance
Where the answers come from. Mentoring: the mentor's knowledge and experience. Coaching: the coachee's own thinking.
Who does most of the talking. Mentoring: the mentor. Coaching: the coachee.
What the helper needs. Mentoring: experience in the field. Coaching: skill in asking questions and listening.
How long it runs. Mentoring: often a longer relationship. Coaching: either a set series of sessions or, more commonly, everyday conversations at work. “Have you got a minute?”
A typical line. Mentoring: "Here's what I did when that happened to me." Coaching: "What options do you see?"
Why the two get confused
The terms are often used interchangeably, which can make coaching capability harder to build. A manager who believes they are coaching may in fact be mentoring: sharing what they would do, rather than helping the other person work it out. Because the conversation feels helpful, the manager rarely practises the harder skill of asking a question and waiting for the answer.
In my leadership development work - one-on-one and with groups and leadership teams - resisting the urge to offer adcice, make suggestion or ask a leading question is the most commonly cited ‘thing to learn’ for leaders wanting to grow their coaching.
To be fair, there is real overlap. Good mentors ask questions and listen too, and the CIPD notes that mentoring works best when it moves beyond a senior colleague "telling it how it is".
The useful test in any conversation is simple: who is doing the thinking?
Why it matters for managers
Telling (mentoring) is usually quicker in the moment. Coaching feels like it will take longer, perhaps because it needs more patience.
I’ve noticed that the more directive a leader’s natural leadership style the more they typically struggle with framing a genuine question and waiting for an answer. I’ve also noticed that people with deep expertise can find it harder to not give answers.
Coaching builds people who can work things out without the leader, and who own the decisions they reach. This is good news for any people leader - what leader doesn’t want more time in their day? So c good coaching is a win-win.
When to coach, when to mentor and when to direct
Mentor, or teach, when the person lacks the knowledge or experience to work it out for themselves: a new starter, or a task they have never done.
Coach when the person is capable but stuck, or when it matters that they own the decision.
Direct when it is urgent, a safety matter, or not up for discussion.
Good managers move between all three, sometimes in the same conversation. Knowing which one the moment calls for is a skill in itself.
One situation, two responses
A team member keeps missing deadlines. Their manager could respond in two ways.
Mentoring response: "When that happened to me, I started blocking out time each morning for my most important task. Try that."
Coaching response: "What is getting in the way of some of your deadlines?" Then: "What might be some things you could do to help you meet them?"
Both are well meant. In the coaching version, the team member does the thinking and chooses the fix, so it suits their situation and they are more likely to follow through.
If they have no ideas, the manager can then offer one, moving from coaching to mentoring on purpose.
What the evidence says
Both approaches have research behind them. A meta-analysis of workplace coaching studies (Theeboom, Beersma and van Vianen, Journal of Positive Psychology, 2014) found significant positive effects on performance and skills, wellbeing, coping, work attitudes and goal-directed self-regulation.
A meta-analysis of mentoring research (Eby and colleagues, Journal of Vocational Behavior, 2008) found mentoring was linked to better outcomes for the people mentored. The authors describe the effects as generally small, and larger for workplace mentoring than for youth mentoring.
The evidence doesn't make one better than the other. They do different jobs.
Three core coaching skills
Coaching can be learned. It rests on three core skills:
Mindset: simply put, believing the person is worth your time.
Asking questions: open questions that make the other person think, rather than ones that lead them to your answer.
Listening: listening to understand rather than to reply, so your next question builds on what they said.
A simple model such as TGROW (Topic, Goal, Reality, Options, Wrap-up) gives a coaching conversation its shape, so the skills have somewhere to go.
Frequently asked questions
Is mentoring the same as coaching?
No. Mentoring passes the mentor's knowledge and experience to the mentee. Coaching asks questions that help the person being coached think for themselves and find their own answers. The terms are often used interchangeably, but they are different skills.
Can a manager be both a coach and a mentor?
Yes. Good managers mentor when someone lacks the knowledge or experience, coach when someone is capable but stuck, and direct when something is urgent. The skill is choosing which one the moment calls for.
Which is better for developing my team?
Neither is better in general; they do different jobs. Mentoring passes on experience quickly. Coaching builds people who can work things out for themselves and who own their decisions. Most teams benefit from both.
