A1 | BEGINNER

I am a security guard. I work in a large office building. At the start of my shift, I put on my uniform and check the security desk. I watch the cameras and look at the doors. Visitors come in and show me their ID. I write their names down and give them a visitor badge. Later, I walk around the building and check that everything is safe.

A2 | ELEMENTARY

At the beginning of my shift, I check the security cameras, radios, and alarm system. I also read the notes from the previous guard so I know if anything unusual has happened. When visitors arrive, I ask who they are here to see and give them a temporary badge. During the shift, I walk through the building and make sure emergency exits are clear. If I notice a problem, I report it straight away.

A2 | BÁSICO

Al principio de mi turno, reviso las cámaras de seguridad, las radios y el sistema de alarma. También leo las notas del vigilante anterior para saber si ha ocurrido algo fuera de lo normal.

Si observo algún problema, lo comunico inmediatamente.

B1 | INTERMEDIATE

Most of my shift is quiet, but I still have to stay alert. I monitor the cameras, check different areas of the building, and keep an eye out for anything unusual. If an alarm goes off, I first find out where it was triggered and then follow the correct procedure. Sometimes a door has simply been left open, but I never take anything for granted. If something does not look right, I check it out before deciding that there is no problem.

B1 | INTERMEDIO

La mayor parte de mi turno es tranquila, pero aun así tengo que mantenerme alerta. Vigilo las cámaras, reviso distintas zonas del edificio y estoy atento a cualquier cosa fuera de lo normal. Si salta una alarma, primero averiguo dónde se ha activado y después sigo el procedimiento correspondiente. A veces simplemente se ha quedado una puerta abierta, pero nunca doy nada por sentado. Si algo no parece normal, lo compruebo antes de decidir que no hay ningún problema.

B2 | UPPER-INTERMEDIATE

Security work involves noticing small details that other people may overlook. If I see someone trying to enter a restricted area, I approach them calmly and ask to see their authorization. Most situations are simple misunderstandings, but I cannot afford to jump to conclusions either way. I have to assess what is happening, follow protocol, and call for backup if necessary. During a busy event, I also need to keep track of entrances, visitors, and access points without letting anything slip through the cracks.

B2 | INTERMEDIO ALTO

El trabajo de seguridad implica fijarse en pequeños detalles que otras personas pueden pasar por alto. Si veo a alguien intentando entrar en una zona restringida, me acerco con calma y le pido que me muestre su autorización. La mayoría de las situaciones son simples malentendidos, pero tampoco puedo permitirme sacar conclusiones precipitadas en ningún sentido. Tengo que evaluar lo que está ocurriendo, seguir el protocolo y pedir apoyo si es necesario. Durante un evento con mucha gente, también necesito controlar las entradas, los visitantes y los puntos de acceso sin permitir que nada se pase por alto.

C1 | ADVANCED

Effective security depends as much on judgment as on surveillance equipment. A camera can show me what is happening, but it cannot always tell me whether a situation is genuinely suspicious. I have to read people's behavior, take the context into account, and distinguish between something harmless and something that warrants closer attention. At the same time, I need to avoid making assumptions based on appearances alone. If a concern arises, the best approach is usually to gather the facts before taking action. Remaining observant without becoming overly suspicious is a delicate balance.

C1 | AVANZADO

Una seguridad eficaz depende tanto del criterio como de los equipos de vigilancia. Una cámara puede mostrarme lo que está ocurriendo, pero no siempre puede decirme si una situación es realmente sospechosa. Tengo que interpretar el comportamiento de las personas, tener en cuenta el contexto y distinguir entre algo inofensivo y algo que merece mayor atención. Al mismo tiempo, debo evitar hacer suposiciones basándome únicamente en las apariencias. Si surge alguna preocupación, lo mejor suele ser reunir los hechos antes de actuar. Mantenerse atento sin volverse excesivamente desconfiado exige un equilibrio delicado.

C2 | PROFICIENT

Professional security work requires restraint as much as vigilance. When something appears out of place, my first responsibility is to establish what is actually happening rather than react to the first impression. A minor inconsistency may prove insignificant, while an apparently routine detail can turn out to be the key to a larger problem. Years of experience have taught me to keep my wits about me, particularly when several things demand attention at once. Were a situation to escalate, I would need to act decisively while remaining within established procedures. The challenge is to stay one step ahead without overreacting, because sound security depends on proportional responses rather than suspicion for its own sake.

C2 | COMPETENTE

El trabajo profesional de seguridad exige tanta prudencia como vigilancia. Cuando algo parece fuera de lugar, mi primera responsabilidad es determinar qué está ocurriendo realmente en lugar de reaccionar ante la primera impresión. Una pequeña incoherencia puede resultar insignificante, mientras que un detalle aparentemente rutinario puede acabar siendo la clave de un problema mayor. Los años de experiencia me han enseñado a mantener la cabeza despejada, especialmente cuando varias cosas requieren atención al mismo tiempo. Si una situación llegara a agravarse, tendría que actuar con decisión sin salirme de los procedimientos establecidos. El reto consiste en ir un paso por delante sin reaccionar de forma exagerada, porque una buena seguridad depende de respuestas proporcionadas y no de sospechar por sospechar.
