Chile is navigating a complex transition in its approach to school security, attempting to balance the urgent need for safety with the fundamental rights of students. Central to this effort is the Ley de Convivencia, Buen Trato y Bienestar de las Comunidades Educativas (Law No. 21.809), which provides a legal framework to prevent and eradicate violence, discrimination, and harassment within educational institutions.
While the law introduces a comprehensive suite of socio-emotional supports, it has sparked significant debate over its provisions regarding security hardware. Specifically, the Ley de Convivencia Escolar detectores de metales allows for the installation of metal detectors and other screening tools to prevent weapons or incendiary devices from entering campuses—a move that comes in the wake of increasing volatility in school environments.
The push for stricter security measures intensified following a tragic attack at the Instituto Obispo Silva Lezaeta in Calama. That event, perpetrated by a student, resulted in the death of a school inspector, left another staff member in critical condition, and injured three students. The tragedy underscored a growing anxiety among parents and educators about the vulnerability of school grounds to violent incursions.
The strict conditions for metal detectors
The law does not grant schools a blanket authorization to install security scanners. Instead, it establishes a high threshold for their utilize. Under the new regulations, school administrators (sostenedores) may implement resources to detect weapons or hazardous materials only when there are “founded reasons” that justify the measure.
According to the legal text, such measures must be “proportional, necessary, and suitable” to prevent the commission of crimes within the establishment. Which means a school cannot simply decide to install detectors as a general deterrent. they must demonstrate a specific, evidence-based risk that warrants such an intervention.
“Solo procederá cuando existan antecedentes fundados que justifiquen su utilización como una medida proporcional, necesaria e idónea para prevenir la comisión de delitos en el establecimiento”
the implementation process is heavily regulated. To deploy these tools, the school must develop an internal protocol that must be approved by the Subsecretaría de Educación. This protocol is required to safeguard the “right to equality and non-arbitrary discrimination, to private life and honor, as well as the best interests of the child, girl, and adolescent.”
These protocols must also establish clear lines of coordination with public security forces, ensuring that if a weapon or incendiary device is detected, the response is immediate, professional, and legally sound.
Beyond security: A systemic approach to coexistence
While the metal detector provision captures headlines, the bulk of Law 21.809 focuses on the psychological and social fabric of the school. The legislation moves away from purely punitive discipline toward a model of “buen trato” (good treatment) and proactive wellbeing.
Every school is now required to maintain a School Council or a Committee for Good Coexistence to promote participation and a culture of respect. More critically, the law mandates the creation of a dedicated educational coexistence team. This team must be led by a Convivencia Coordinator who possesses pedagogical or psychosocial training, ensuring that conflict resolution is handled by experts rather than solely by administrative staff.
This team is responsible for executing the school’s Management Plan for Educational Coexistence. These plans must align with national policies and address several critical pillars:
- Conflict Resolution: Implementing mediation and peaceful resolution strategies.
- Digital Safety: Managing digital responsibilities and preventing cyber-bullying.
- Mental Health: Integrating socio-emotional development and risk prevention from a pedagogical perspective.
- Accountability: Creating safe, anonymous reporting channels for harassment with a strict two-month investigation window for student cases.
The socio-emotional wellbeing initiative
Recognizing that violence is often a symptom of deeper emotional distress, the law proposes the creation of the Programa de Bienestar Socioemocional Escolar. This voluntary program targets students from 3rd grade (básico) through 3rd year of high school (medio). Rather than traditional classroom instruction, the program uses sports, cultural activities, and scientific workshops to foster essential socio-emotional skills.
Implementation timeline and requirements
The transition to these new standards is not instantaneous. The law entered into force three months after its publication in the Diario Oficial. During this initial window, the Ministry of Education (Mineduc), the Superintendence of Education, and the Education Quality Agency are tasked with a massive rollout of training and consultation for school communities.
For schools that are subsidized or receive state funding, there are specific deadlines for the most critical safety and reporting components.
| Requirement | Deadline | Applicability |
|---|---|---|
| General Entry into Force | 3 Months post-publication | All Schools |
| Anti-harassment Protocols | 9 Months post-entry | Subsidized/State-funded |
| Secure Reporting Channels | 9 Months post-entry | Subsidized/State-funded |
This phased approach is designed to prevent schools from rushing into the implementation of security protocols without the necessary training or the approval of the Subsecretaría de Educación.

The next critical phase for the educational community will be the release of the formal guidelines from the Subsecretaría de Educación, which will define the exact criteria for what constitutes “founded reasons” for the use of metal detectors. These guidelines will determine whether the law becomes a tool for targeted safety or a source of further tension within the classroom.
