Every year in France, tens of thousands of students live in fear of school bullying in establishments where adults — although present, although concerned — do not have the tools to see what is happening, name what they see, or act consistently with their colleagues. This is not a lack of good intentions. It is a lack of training.

International research is clear on this point: training educational teams is the most effective individual lever to reduce the prevalence of bullying and improve the quality of the institutional response when it occurs. More than posters in hallways, more than student awareness days, more than revised internal regulations — what sustainably changes practices is a team of adults who share the same frame of reference, the same vocabulary, and the same action tools.

This guide is aimed at school principals, heads of establishments, human resources directors, and school counselors who wish to organize training on school bullying for their team. It covers the why, what, how, and how much — with concrete answers at each stage of the decision.

1. Why good intentions are not enough: the case for training

Resistance to training on school bullying often takes the form of a reasonable objection: "our teams know what bullying is, they have common sense, why formalize?" This objection deserves a direct and documented response.

Common sense does not recognize bullying in time

Studies on the detection of bullying consistently show that untrained adults systematically underestimate the prevalence of bullying in their establishment. They detect on average 30 to 40% of the situations that actually exist — and even then, often late, when they are already at an advanced stage. This is not because they are indifferent: it is because they do not know exactly what to look for, how to interpret what they see, or how to distinguish bullying from an ordinary conflict.

Training provides precisely these tools: diagnostic criteria, behavioral and relational warning signals, the evaluation grid that allows qualifying a situation. With these tools, the same adult observing the same student sees things they did not see before — not because they have become more attentive, but because they now know what their attention should seek.

Common sense does not coordinate a team

Even an adult who detects a situation cannot act effectively alone. Managing bullying is a collective approach that involves several professionals, several hierarchical levels, and several types of simultaneous actions. Without common training, each adult improvises according to their own representations — and the resulting incoherence is often perceived by bullies as a flaw to exploit.

Collective training creates a common language, shared procedures, and a culture of coordination. It allows the teacher, the school counselor, the nurse, and the social worker to "speak the same language" when discussing a concerning situation, which drastically reduces delays and misunderstandings.

Common sense does not provide legal protection

As the legal framework now clearly imposes (law of March 2, 2022), establishments are obliged to train their staff. An establishment whose staff have received no formal training on bullying and in which a serious situation has occurred is in a position of significant legal weakness. Certified training is tangible proof that the obligation of competence has been fulfilled.

📊 What research says about the impact of training. A meta-analysis of 53 intervention programs against school bullying in 11 countries (Ttofi & Farrington, Cambridge, 2011) concludes that programs including intensive training for adults reduce the number of victims by an average of 20 to 23% and the number of bullying perpetrators by 17 to 20%. Adult training is identified as the most important effectiveness variable, ahead of programs focused solely on students.

2. What a team training actually changes

The effects of a well-designed and well-facilitated training manifest at several levels, within relatively short timeframes after the training.

More numerous and earlier reports

The first observable effect is an increase in the number of internal reports in the weeks following the training. This effect may seem paradoxical — "are we reporting more bullying, so is there more?" — but it actually reflects an improvement in detection, not a worsening of the phenomenon. Situations that existed without being recognized become visible. Trained adults are also more willing to report their concerns, knowing they have a framework to address them.

Faster and more consistent interventions

The second effect is a reduction in the time between detection and intervention. In untrained establishments, this delay can reach several weeks — the time it takes for information to circulate, for responsibilities to clarify, for someone to take the initiative. In trained establishments, this delay drops to a few days, sometimes just a few hours for the most urgent situations.

A strengthened sense of competence and professional security

Trained teams unanimously report a strengthened sense of competence and professional confidence when facing bullying situations. This feeling is not anecdotal: it reduces anxiety in difficult situations, promotes action rather than avoidance, and strengthens team cohesion around a subject that was often a source of tension and disagreement.

Before the training, when a student came to see me to talk about a difficult situation, I had a knot in my stomach because I didn't really know what to do. Afterwards, I still had empathy and emotion — that's human — but I also had a framework. I knew the first questions to ask, I knew who to escalate the information to, I knew what to say to the parents. It changes everything to know that we are no longer improvising.
