Sales education vs sales training: why 70% of your training is forgotten in 7 days

You drive the skills development of sales teams. You invest in serious training programmes, led by good facilitators, with satisfied participants at the end of the session. And yet, a few weeks later, out in the field, little has changed. It's not your fault, nor the trainers', nor a lack of will from the sales reps. It's a mechanical problem, and as long as it goes unnamed, you keep investing in a scheme that evaporates.

The hidden cost of one-off training

The forgetting curve described by psychologist Hermann Ebbinghaus leaves no room for doubt: without regular reactivation, we forget most of what we learn within a few days. Applied to a classic top-down training course, it means 70% of content lost in less than seven days. With a “two days in a classroom, once” format, you reach around 80% forgotten at three months.

Translated into budget terms, it is staggering: most of the “training” line never turns into lasting skill. You are funding a rise in competence, the bulk of which has vanished before the next quarter. This is not an argument against training, it is an argument against training with no follow-up.

The test is easy to run in-house: revisit what a session covered the next day, then again a week later. The gap between what participants thought they had retained and what they can actually recall is striking every time. That gap is exactly what explains the recurring frustration between a training course that succeeded on paper and a field that does not move.

It's not a motivation problem

Faced with this, the reflex is often to look for someone to blame: sales reps who aren't involved enough, a trainer who isn't compelling enough, content that was poorly calibrated. It is almost always a false trail. Forgetting isn't a lack of seriousness, it's how the brain normally works: whatever isn't reactivated fades away. No reminder, no end-of-session evaluation, no “well-made” handout will get around that law.

The implication is liberating for a training director: the answer is not to convince better or to present better, it is to reactivate. What lasts over time is not what was explained well once, it is what was repeated several times.

Education or training: it's not one against the other

The mistake would be to pit one against the other. Education remains essential to onboard newcomers and pass on the fundamentals: this is when people discover concepts and a shared framework is set. Nobody gets good by skipping that step. But once onboarding is over, the need changes in nature.

For the vast majority of sales reps already in post, the challenge is no longer learning a new concept: it's repeating the key moves: opening, questioning, reformulating, arguing, handling objections. Until they become natural and adaptable. In other words: education lays the foundations, training embeds them. One prepares, the other turns knowledge into reflex.

Thinking in terms of a skills journey rather than a training catalogue changes how you allocate budget: fewer isolated classroom days, more regular and measured practice behind them. It's not about spending more, it's about spending differently.

Compatible with your regulatory framework

In France, training operates within a precise framework: OPCO funding, Qualiopi certification, sometimes accredited qualifications on the official register. The good news is that continuous training does not replace it, it adds to it. You keep your certified programmes and your fundamentals; you graft on a reinforcement system that extends their effect over time, where today the programme stops at the debrief.

In practice, regular training becomes the natural extension of a training initiative: it fits into the skills development plan as the phase that turns theoretical knowledge into sustained practice. It also answers a growing expectation from funders and executive teams: proving that the training effort produces a real effect in the field, and not just an attendance certificate.

Finally measure impact, not just satisfaction

Kirkpatrick's model sets out four levels of evaluation: satisfaction (did people enjoy it?), learning (did they learn?), behaviour (has practice changed in the field?) and results (has performance improved?). In practice, most programmes stop at the first: the famous “happy / not happy” questionnaire.

Continuous training moves you up a level, then two. You look at the change in behaviour (is the sales rep questioning better, reformulating, daring to book more sales meetings?), at intermediate indicators (meeting booking rate, quality of discovery, objection handling), and, when the sales cycle allows it, at results. Not every training programme can be evaluated on results — a two-year sales cycle rules out calling back in two years — but you can always look at what has shifted in behaviour and in intermediate measures.

The Kirkpatrick model: moving beyond a simple “happy / not happy”.

From training budget to skills pathway

For an HR department, the real shift in perspective is this: stop thinking in terms of isolated “training actions” and start thinking in terms of journeys. A journey means a education phase to lay the fundamentals, then a phase of regular training to embed them, and occasional coaching from the manager to tie it all back to the field. The same budget then produces a lasting effect instead of a peak that quickly fades.

This framing also makes the conversation with senior management easier. Instead of defending a number of training days, you defend measurable progress: skill levels that rise, behaviours that change, indicators that move. Training stops being a cost and becomes an investment whose return you can track.

The key role of the coaching manager

No setup holds up without managers. But you can't ask them to coach every sales rep every week: they don't have the time. That's where AI comes in: it takes on the training volume and a first, immediate debrief, while the manager focuses on high-value coaching, on real situations, ideally once or twice a month.

Combining the two multiplies the manager's impact, for a very modest time investment on the sales rep's side: around fifteen to twenty minutes a week. Managers, meanwhile, shift from a control role to developing their people. An evolution many of them are waiting for, provided they are equipped and supported to take it on.

Roll out simply, without upending everything

There is no need to change everything at once. Roll-outs that work come down to five principles. Start small and targeted: one skill, one simulator, one short team rather than everything at the same time. Anchor it in a ritual: fifteen minutes before a key sales meeting, or to open the weekly team meeting. Make the manager the driving force: they launch the challenge and run the debrief. Kick off with a challenge: friendly competition drives adoption far better than an instruction. Measure from week one: the dashboard makes the impact visible straight away.

You then extend it to the other teams, once the routine is established and the first results shared. This is the approach we designed with the BizCoach AI voice training platform, as a direct extension of what our pillar article describes on the end of classic sales education.
