What Makes Good Coaching? The 7 Quality Markers of Evidence-Based Practice

You recognise good coaching by a solid working relationship, clear goals, and demonstrable impact, not by certificates on the wall. Coaching research names seven quality markers that a professional process meets:

• Relationship quality: The working alliance is the single strongest success factor (correlation r = .41 with the coaching outcome).
• Goal clarity: Concrete, verifiable goals instead of vague intentions.
• Method flexibility: The coach adapts the approach to you, not you to their favourite method.
• Feedback loops: Regular check-ins instead of blindly carrying on.
• Supervision routine: The coach has their own work reflected on externally.
• Closure contract: A defined ending instead of endless dependency.
• Measurable impact: Change you notice in everyday life, not just in the conversation.

In Switzerland, "coach" is not a protected title. That is exactly why you need your own quality measure. This article gives you both perspectives: for coaches a self-check, for clients a checklist before booking.

Why do you even need a quality measure for coaching?

You need your own quality measure because the coaching profession is legally unprotected in Switzerland. Unlike psychologists, whose title is governed by the Psychology Professions Act (PsyG), anyone in Switzerland may call themselves a coach. There is no state licence, no supervisory authority, no mandatory training. That is not a side detail but the core reason why quality varies so widely across the coaching market.

This gap weighs heavily because it shifts all the risk onto the client side. Whoever books a poor coach loses money and time, and in the worst case trust in the method itself. For coaches, the same gap means something else: those who deliver quality must make it visible, otherwise it drowns in the noise of the self-appointed.

The good news: coaching is well researched. Four decades of impact studies provide robust effect sizes and name the factors that separate a good process from a mediocre one. The following seven markers come from that research, not from association marketing. If you want to know how strongly coaching works, you will find the numbers in our piece Does Coaching Actually Work? What 40 Years of Research Show.

What is the most important quality marker: relationship quality?

Relationship quality is the most important quality marker because the working alliance is the single strongest outcome predictor in coaching. The meta-analysis by Grassmann and colleagues across 27 studies found a correlation of r = .41 between the strength of the working relationship and the coaching outcome (Grassmann et al., 2020). No methodological tool reaches this predictive power. The relationship is not the nice wrapping. It is the active ingredient.

The working alliance has three parts: a solid bond of trust, agreement on goals, and agreement on tasks. That matters because it makes relationship quality measurable instead of leaving it diffuse. You feel it in concrete things: the coach listens without rushing to solve. They tolerate silence. They contradict you when needed instead of telling you what you want to hear.

How do you check your relationship quality as a coach?

As a coach, you check your relationship quality by gathering brief feedback after every third or fourth session. A single question is enough: "On a scale of one to ten, how well understood do you feel in our process?" Anyone landing below eight has a relationship problem, not a method problem. This routine costs two minutes and prevents the most common silent dropout.

How do you recognise a good relationship as a client?

As a client, you recognise a good relationship when, after the first session, you feel heard and not judged. Ask yourself concretely: Did I talk more than the coach? Did they summarise my situation in their own words before moving on? A good coach follows your pace. A weak one follows their script.

Why is goal clarity a quality marker?

Goal clarity is a quality marker because good coaching begins with a verifiable goal and not with a feeling. Coaching differs from a good conversation among friends at exactly this point: it has a direction. Studies show the strongest effects on reaching self-set goals and on self-regulation, with effect sizes up to g = 0.74 (Theeboom et al., 2014).

Goal clarity weighs heavily because without it no one can say whether the coaching worked. A vague "I want to become more confident" is not a goal but a wish. A good goal sounds different: "Over the next twelve weeks, I want to hold three salary conversations without cancelling beforehand." That is observable. That is verifiable. Progress can be pinned to it.

How do you sharpen goal clarity as a coach?

As a coach, you sharpen goal clarity by translating every goal into a concrete action before the actual process starts. Ask for the first observable step: "How would the people around you notice that something has changed?" If the client cannot answer this question, the goal is not yet ready. Put it in writing. A noted goal commits differently than a spoken one.

What should you ask about the goal as a client?

As a client, you should ask in the first conversation how the coach defines and reviews the goal with you. A good coach has a clear answer and does not retreat into generalities. If the answer is "That develops over time," with no structure at all, that is a warning sign. Methodical clarity often shows in this single question.

What does method flexibility in coaching mean?

Method flexibility means that a good coach adapts their approach to you instead of forcing you into their favourite method. The research on active ingredients is clear: it is not the individual method that decides, but the common factors such as relationship, hope, and self-efficacy (De Haan, Active Ingredients of Coaching). A coach who imposes the same model on every client is working past the method.

That matters because method dogmatism is a widespread quality flaw. Whoever only knows GROW sees a GROW problem in every situation. A flexible coach masters several approaches and chooses deliberately. We have placed the most important models and their use in Coaching vs. Therapy vs. Counselling vs. Mentoring, so you can place the language your coach uses.

Method flexibility does not mean arbitrariness. A good coach explains why they choose this path right now.

Flexibility also shows in the format. Some topics need the depth of a planned session, others quick access in between. A professional scheduling system and access to spontaneous live sessions without waiting give a coach exactly this room to fit the format to the topic rather than the other way around.

Why do feedback loops belong to good coaching?

Feedback loops belong to good coaching because they prevent a process from drifting blindly in the wrong direction. A professional coach builds in fixed points where coach and client take stock together: Where are we? What works? What does not? This routine weighs heavily because it allows course corrections while they are still cheap.

Without a feedback loop, no one notices that a goal no longer fits or a method is running into a void. The coaching then trickles on, everyone is polite, and in the end the client wonders what it actually achieved. Studies on the effect of short, structured feedback show that even a simple scale question per session noticeably improves the outcome.

How do you install feedback loops as a coach?

As a coach, you install feedback loops by reserving two minutes after each session for structured feedback. Ask about the value of the session and about what was missing. Record the trajectory so that patterns become visible. An integrated client management system turns these notes into a real history instead of scattered scraps.

How do you spot missing feedback loops as a client?

As a client, you spot missing feedback loops when the process itself is never discussed. If, after ten sessions, you have never paused to ask whether you are on course, a central quality element is missing. You may ask this question yourself. A good coach welcomes it.

Why is supervision a sign of quality?

Supervision is a sign of quality because a good coach has their own work reflected on externally instead of assuming they are flawless. Coaching supervision is a structured process in which a coach discusses their cases with a qualified supervisor. Research shows that coaches with regular supervision achieve more self-reflection, more objectivity, and better outcomes for their clients (Institute of Coaching).

That weighs heavily because the coach is alone in the conversation. No one watches, no one corrects blind spots. Supervision is the only structured counterbalance. A coach without a supervision routine works without a corrective, and over the years it shows in the quality. How supervision, intervision, and peer coaching differ and what they cost in Switzerland is covered in Supervision and Intervision for Coaches.

What is the supervision routine for you as a coach?

The supervision routine is, for you as a coach, the regular reflection on your practice with an external supervisor or a peer group. Schedule it firmly, not only when problems arise. A fixed frequency, say monthly, keeps quality constant. Whoever seeks supervision only in a crisis has it too late.

May you ask about supervision as a client?

As a client, you may ask directly about the supervision routine in the first conversation. The question is simply: "Do you have your work supervised regularly?" A professional coach confirms this without hesitation. Whoever dodges or finds the question strange probably has no corrective.

Why does good coaching need a closure contract?

Good coaching needs a closure contract because a professional process works towards its own redundancy. Coaching is help towards self-help. The aim is that the client eventually carries on without a coach. A defined ending from the start separates serious coaching from dependency relationships that mainly secure the coach's revenue.

This marker weighs heavily because there is a real conflict of interest here. A coach earns from every further session. Whoever still speaks about the ending from the beginning puts the client's interest above their own. That is precisely what professionalism is. A good closure contract sets out after how many sessions you take stock together and when the process sensibly ends.

Why is measurable impact the final quality marker?

Measurable impact is the final and decisive quality marker because good coaching produces a change you notice in everyday life. The large randomised field trial by De Haan and colleagues in a healthcare corporation found effect sizes up to d = 1.1, a very strong value in social research (De Haan et al., AMLE). Coaching works demonstrably when it is done well. That is exactly why impact may be visible.

That matters because impact is not proven in the conversation but in the behaviour afterwards. Good coaching shows in the fact that you do things you previously avoided. You have the conversation you had postponed. You make the decision that had been left lying. The session itself can feel pleasant and still be ineffective. The test lies in the Monday after.

How do you measure your impact as a coach?

As a coach, you measure your impact by the distance between the starting goal and the position at the end of the process. Use the goal scale you defined at the start and compare the value. Ask the client which concrete action they now show that was not possible before the coaching. These behavioural proofs are your best impact record and at the same time your most credible reference.

How do you recognise real impact as a client?

As a client, you recognise real impact when your behaviour changes, not just your insight. Insight is pleasant but cheap. After a few weeks, ask yourself: What do I do differently today? If the answer is concrete, the coaching worked. If it stays vague, either time or quality is missing.

How do you use the 7 quality markers as a self-test?

You use the seven quality markers as a self-test by rating each marker on a scale from zero to three and adding up the total. Zero means "does not apply," three means "fully met." That gives a maximum of 21 points. Go through the following seven scenarios honestly, once from your role as a coach, once as a client.

• Relationship quality: Do you actively gather feedback on the relationship after every third to fourth session? Three points for a fixed routine, zero for gut feeling.
• Goal clarity: Is the goal written, observable, and fitted with a first concrete step? Three points for full sharpness, zero for a vague wish.
• Method flexibility: Do you master more than one approach and choose deliberately? Three points for a justified choice, zero for a one-size-fits-all model.
• Feedback loops: Are there fixed points where you discuss the process itself? Three points for every session, zero for never.
• Supervision routine: Do you have your work supervised externally on a regular basis? Three points for a fixed frequency, zero for never.
• Closure contract: Is it clear from the start when and on what the process ends? Three points for a defined ending, zero for an open-ended marathon.
• Measurable impact: Do you prove change through concrete behaviour, not just insight? Three points for behavioural proof, zero for pure feeling.

Here is how to read your result: 18 to 21 points stand for a considered practice. 12 to 17 points show a solid base with clear weak spots. Under 12 points the foundation is missing, no matter how likeable the coach seems. For clients: have the weak markers explained in the first conversation before you book.

What training does a good coach need in Switzerland?

A good coach in Switzerland needs solid, formal training, even though the state prescribes none. Because the title is unprotected, training is not a mandatory proof but a voluntary quality signal. There is, however, a recognised reference point: the federal professional examination for the operational mentor with a federal diploma. This title is protected and recognised by the federal government (SBFI, Recognition of Professional Qualifications). In Switzerland, serious coaching usually costs between CHF 150 and CHF 350 per hour, depending on experience and field. Price alone is no quality seal, however, a high hourly rate guarantees no better support.

That matters because a federal diploma proves a minimum of structured training. But it does not replace a quality judgment. There are excellent coaches without this title and mediocre ones with it. The seven markers above say more about actual quality than any certificate. A recognised certification is a good starting filter, not the final verdict.

This is where the market becomes decisive. Coaches who make their quality visible in a structured way stand out from the noise of the self-appointed. A platform with verified profiles, genuine reviews, and a transparent process gives serious coaches exactly that advantage. On bondigoo you find coaches with a traceable background in the bondigoo coach directory, and as a coach you build a profile there that proves your quality rather than merely claiming it.

How does bondigoo implement quality structurally?

bondigoo implements quality structurally by supporting exactly the seven markers that make good coaching. Instead of only promising quality, bondigoo builds it into the working day. That is the difference between a directory and a real tool.

In concrete terms: an integrated client management system keeps the history of every client, so that feedback loops and goal progress stay visible. A professional scheduling system gives the process structure, while live sessions without waiting create the necessary flexibility for spontaneous topics. Structured coaching programs help set a clean start and a defined ending, anchoring the closure contract technically. Here is how it works in detail: How bondigoo works.

For clients, that means less risk in the choice. For coaches, it means that their quality does not evaporate into claims but becomes visible in a clean process. The platform works without monthly fixed costs and takes only a fair commission per booking, so the start stays low-risk too.
