Key findings
Carter and Miller found the full range of expected business benefits in only half of the internal coaching programmes they evaluated.
In one public sector analysis, 37 of 220 coachee objectives were directly aligned to organisational outcomes.
Supervision is mandatory in counselling and still optional in coaching, so a pool has to make it a condition of membership.
Passmore and Crabbe recommend that internal coaches sit outside the line management relationship of the people they coach.
A coach with two clients meeting fortnightly logs about 50 hours a year, so supervision has to supply experience the caseload cannot.
In an analysis of 88 coachee action plans, 37 of 220 objectives were directly aligned to organisational outcomes.
An internal coaching programme works when four decisions are made before any coach is trained. They cover which conversations the pool takes, who is released to coach, who supervises from outside the reporting line, and what each coachee's manager agrees at the start.
Pools built without those decisions tend to produce trained coaches with few clients, or clients whose objectives have little to do with the business.
Carter and Miller of the Institute for Employment Studies reported in 2009 that only half of the internal programmes they had evaluated achieved the full range of expected business benefits.
Their evidence came from interviews with 97 coachees, 49 internal coaches, 64 line managers and ten senior sponsors.
They traced the shortfall to a weak link between the scheme and a business need at the outset.
The same weakness shows in what coachees choose to work on.
In an analysis of 88 coachee action plans at a large public sector employer, 37 of the 220 objectives listed (17 per cent) were directly aligned to organisational outcomes.
The practitioner who sets up the pool therefore has two jobs, which are building the coaching capacity and agreeing with the business what it is for.
Internal Coaching Programme Scope
An internal pool answers a narrower question than external coaching, and the scope belongs in writing before recruitment starts.
It suits development conversations for managers at scale.
Carter and Miller find it helps most during a merger, on a move into a first people-management role, and on appointment to an unfamiliar senior role.
It does not suit a senior person whose issue cannot be discussed inside the organisation, a transition into a materially larger role, or anything that touches performance management.
Those cases stay external, and the pool exists so that the external budget can reach them.
Hawkins and Turner describe five stages of internal coaching and say organisations need not aim for the top one.
A first-year pool can reasonably aim for the third stage, managed by a sponsor with a selected group of coaches.
The cases the pool refuses need a referral route, and when coaching is the wrong answer sets out the tests for them.
The Sponsor Conversation
The practitioner usually proposes the pool, so the first conversation is with the person who will be asked to defend it.
That person is typically the HR director, or a divisional head whose managers are the first intended clients.
Four questions settle the scope in that conversation.
Which population is the pool for, by role and headcount
What business result would count after year one
How many hours of coach time will the business release
Which cases will the pool refuse
Carter and Miller argue that a business paying for coaching should say what business benefits it expects and be clear about the success criteria.
They suggest that coachees keep their private objectives and declare at least one to the sponsor, tied to a current priority.
A sponsor who agreed a measure in advance has something to defend in the first budget round.
The wider case for a people programme is covered in building a business case for a people programme.
Selecting Coaches
Volunteer pools fill with people who want the label rather than the work, so selection needs criteria that a volunteer can fail.
Five criteria produce a usable set.
Credibility with the population they will coach
Capacity, agreed with their own manager in writing
Willingness to be supervised and corrected
Evidence of listening rather than advising
No role in assessing, selecting or calibrating their coachees
The fourth criterion can be tested in twenty minutes.
Give the candidate a live problem from a colleague and note how long they last before offering a solution.
Rogers calls the habit advice in disguise, which is a solution phrased as a question and recognisable by its first word, such as Have, Was, Is or Would.
Four minutes without advising is a reasonable working threshold for starting training.
It comes from practice and has no research behind it.
The fifth criterion matters most for HR staff, who often have both the skills and a stake.
An HR business partner who sits in calibration cannot coach the people being calibrated.
Passmore and Crabbe add that the pool should mirror the make-up of the organisation, and that managers should choose their coach from it.
Accreditation is a separate decision.
The University of Virginia's internal coaching service for leaders uses staff who hold, or are working toward, a certificate from an accredited coaching programme.
Passmore and Crabbe note that accredited training gives recognition that supports business value, and that a bespoke programme is the alternative where size and demand justify one.
What The Training Covers
Most internal coach training teaches a model and stops, and four things matter more than the model.
Contracting, meaning what the coaching is, what it excludes and what happens to what is said
Boundaries, meaning when to stop and refer
The pull toward advising, which is a habit to unlearn
Practice with observation, since coaching is learned by doing it and being watched
A programme that is half practice and half content is roughly the right shape, and most are the other way round.
Carter and Miller recommend giving trainee coaches real coachees early, because a novice without a coachee struggles to retain the training.
They also warn that a gap of more than six months between qualifying and the first client risks the need for refresher training.
Potential clients accept a short waiting list for free coaching, whereas coaches mind a long gap before they use their new skills.
The first clients should therefore be recruited before the course ends.
A coach with two clients meeting fortnightly logs about 50 hours a year.
Supervision Structure
A pool without supervision has no quality control and nobody to take an ethical question to.
Rogers points out that a coaching supervisor has no line responsibility for the coach, which is the opposite of a supervisor in the managerial sense.
Iordanou and Hawley give supervision three functions.
They are developing the coach's skills, protecting the coach's wellbeing, and maintaining quality and ethical standards.
They note that supervision is mandatory in counselling and psychotherapy and still optional in coaching.
A pool therefore has to make it a condition of membership.
The CIPD coaching and mentoring factsheet, dated August 2025, says internal and external coaches both need structured chances to reflect on their practice, one to one or in groups.
Three forms work at internal scale.
Group supervision, six coaches with an experienced supervisor, every six weeks
Paired review, where two coaches discuss a case with names removed
One observed or recorded session a year, with the client's consent
An accredited external supervisor is the cleanest choice, since they have no stake in the organisation.
Two rules make it safe.
Cases are discussed without identifying the client.
Anything that would require breaking confidence goes to the pool lead as a question rather than a disclosure.
Rogers estimates that about 1,000 hours of practice make a coach experienced enough for the range of everyday situations.
A coach with two clients meeting fortnightly logs about 50 hours a year.
An internal coach will therefore spend years below that level, and supervision has to supply the experience that the caseload cannot.
Matching And Confidentiality
Internal coaching has a structural problem that external coaching lacks.
The coach and the client work in the same organisation and may compete for the same roles.
Four rules contain it.
Never coach inside your own reporting line, in either direction
Never coach someone you may assess, select or calibrate
Let the coachee choose after a first meeting with the coach
State the confidentiality position in the first session, including the exceptions
Passmore and Crabbe recommend that internal coaches sit outside the line management relationship of their coachees.
Foy gives the exceptions for an external coach as serious criminality or serious risk of harm.
An internal pool should add any legal reporting duty that applies in its own jurisdiction.
Whitmore adds that communication with the coachee's manager or sponsor should go through the coachee, so that the coachee owns the relationship with the organisation.
The Three-Way Contract
Carter and Miller found that even where a three-way contract was adopted, the line manager often took no active part.
Where managers did take part, a local government evaluation found significantly higher coachee satisfaction, and two NHS programmes produced more organisation-related objectives.
Foy goes further for multi-stakeholder work.
She advises against starting coaching at all without a pre-coaching conversation among the parties.
Four items agreed in the first session prevent most of what goes wrong.
What the client wants, stated as something observable rather than a feeling
How many sessions, over what period, and who books them
What the sponsor will be told, and by whom
What would show both parties at the end that it was worth the time
The coachee's manager joins part of that first session to hear the declared objective and the success measure.
A one-page note to the manager covers time away from work, practice assignments and how progress will be reviewed.
When To Refer Out
Internal coaches meet situations they should not hold, and the referral is the skill.
Four triggers are worth teaching.
Distress that persists beyond the session
Anything disclosed about conduct, safety or harassment
A performance issue the manager has not raised directly
A situation where the coach has a stake in the outcome
The third is where a pool is most likely to be used for avoidance.
The answer is to send the conversation back to the manager rather than hold it on their behalf.
Coaching inside a line role covers the manager's side of that boundary.
Coach Workload
Four commitments make internal coaching sustainable on top of a full role.
Time protected in the coach's own objectives
A cap on clients, usually two or three
Supervision provided rather than sought
Development that continues after the first course
The cap is the first to be breached.
A coach carrying five clients alongside a full role will drop the coaching, and the client learns that the organisation was not serious.
Measuring The Pool
Satisfaction with a coach measures rapport, which is not what the sponsor funded.
Carter and Miller note that return on investment figures often come out well only in established programmes, and they rely on historical data.
They recommend two lead indicators.
Client sign-up against capacity matters most in a new pool, and coach utilisation matters most in an established one.
Four further measures cover the pool itself.
Goals agreed at the start and reviewed at the end
Sessions held against sessions scheduled
Referrals out, which show whether boundaries are working
Coaches still active after twelve months
A pool that has made no referrals in a year is probably holding cases it should have sent elsewhere.
Add the one measure the sponsor agreed in the first conversation.
Training evaluation covers how to collect that evidence.
The First-Year Sequence
Five roles need a name before the pool starts.
They are the sponsor, usually the HR director, the pool lead, an HR business partner or L&D head, an external supervisor, and the line managers of coaches and coachees.
The months below are a working schedule from practice, and demand will move them.
In month one, the pool lead agrees the population, the refused cases and the success measure with the sponsor.
In month two, the pool lead secures written time release from the line managers of candidate coaches.
In month three, candidates take the listening test, and the pool lead and supervisor select.
In months four and five, training runs, with the first coachees booked before it ends and group supervision starting with the first sessions.
In month nine, the pool lead reviews sign-up and utilisation with the sponsor.
In month twelve, the year-one report gives goals met, sessions held, referrals out, coaches active and the sponsor's measure.
Costs To Declare
Internal coaching is often described as free, but three costs belong in the proposal.
Coach time is salary spent on something other than the role.
Training and supervision recur every year and most proposals omit them.
Coordination is a named person's part-time job.
Carter and Miller cite a 2008 estimate of about £50 per hour for coaching through the BBC's in-house network.
They suggest that a pool matching that figure can show value for money.
When Not To Build One
Three conditions make an internal pool a poor investment.
The first is no capacity to supervise, which makes the pool unsafe rather than merely ineffective.
The second is a population small enough for external coaching to be affordable.
The third is a culture where confidentiality is not credible, so the pool will be used for nothing real.
The third condition can be diagnosed in advance by asking three people whether they would take a problem to an internal coach.
Where the answer is no, build the confidentiality first.

Questions this answers
How do you set up an internal coaching programme?
Agree the population, the cases the pool will refuse and a success measure with the sponsor. Select coaches against criteria they can fail, train them with real clients waiting, arrange supervision outside the line, and use a three-way contract in every first session.
How do you select internal coaches?
Look for credibility with the population, capacity agreed in writing with their manager, willingness to be supervised, evidence of listening, and no role in assessing their coachees. Test listening by giving them a live problem and noting how long before they advise.
Do internal coaches need supervision?
Yes. Supervision is mandatory in counselling and still optional in coaching, so a pool has to require it. Group supervision every six weeks with an external supervisor, paired case review and one observed session a year all work at internal scale.
How do you keep internal coaching confidential?
Keep coaches outside the reporting line of their coachees and never let them assess, select or calibrate them. State the confidentiality position in the first session, including the exceptions, and route any message to the manager through the coachee.
What are the pros and cons of internal vs external coaches?
Internal coaches cost less per hour, know the organisation and can reach managers at scale. They work in the same hierarchy as the coachee, so objectivity and confidentiality need rules. Senior, sensitive or large-transition cases usually stay with external coaches.
How do you measure the impact of an internal coaching programme?
Track client sign-up against capacity and coach utilisation as lead indicators. Then report goals agreed and reviewed, sessions held, referrals out, coaches still active after twelve months, and the one business measure the sponsor agreed at the start.
