Social & emotional learning	Social & emotional learning Bangkok Patana School places a strong emphasis on helping students understand and manage their emotions, build healthy relationships, and make responsible decisions. In the Primary School, social and emotional learning is embedded into classroom life through interactive activities, themed days, and storytelling. Younger students, for example, participate in “well-being chats” such as sharing pet photos to build empathy, connection, and emotional vocabulary. In Secondary, SEL is structured into the weekly Tutorial Programme, where students explore themes like emotional regulation, digital safety, personal values, and social health. These sessions often include group discussions, real-life scenario explorations, and guest speakers. A notable example of integrated SEL is a Year 8 project where students used drama to explore complex emotions, inspired by Inside Out 2. Through creative techniques like movement, tableau, and scriptwork, students practiced identifying and expressing emotions while applying the Zones of Regulation framework to build self-awareness and resilience.	Social & emotional learning ISB integrates social and emotional learning through its counseling services, which address students' academic, social, and emotional needs. The school provides universal services for all students, targeted small-group support, and intensive interventions for those with higher needs. Counselors collaborate with students, parents, and faculty to ensure appropriate levels of care .
Special educational needs (SEN)	Special educational needs (SEN) Bangkok Patana has a dedicated Inclusion and Student Support team that provides services for students with mild to moderate learning needs. This includes Learning Support teachers, educational psychologists, speech and language therapists, and occupational therapy referrals when needed.

The school also encourages a whole-school inclusive approach, where students with learning differences participate in mainstream classrooms with appropriate accommodations and support.

A dedicated Social and Emotional Counselling Team includes both full-time and part-time professionals who provide confidential, one-on-one support to students. This team also works closely with parents and staff, reinforcing a community-wide approach to emotional health. In Secondary, the school has introduced the AWE Well-Being Survey, a proactive tool to monitor how students feel over time. This data informs individual support strategies and led to the creation of “The Hub” a quiet, calming space designed for students to decompress, reflect, or access counselling services. Beyond structured support, the school frequently hosts awareness workshops that address issues such as social media pressure, emotional balance, and mental health strategies.	Mental wellbeing ISB's counseling services address students' academic, social, and emotional needs, providing universal services for all, targeted small-group support, and intensive interventions for students with higher needs. Counselors work collaboratively with students, parents, and faculty to ensure every student receives appropriate care .
Safeguarding	Safeguarding Bangkok Patana School’s Safeguarding Policy outlines a whole-school commitment to protecting students from harm, including neglect, exploitation, and all forms of abuse. It defines safeguarding as the school’s duty to ensure students are cared for by vetted adults, learn in a safe environment, and are educated about personal safety. All staff, parents, visitors, and contractors must adhere to specific safeguarding codes of conduct, and students are taught age-appropriate safety skills through the curriculum. The policy aligns with both Thai law and UK guidance, emphasizing non-physical discipline, digital safety, and protection from issues such as radicalisation, FGM, and child exploitation. Designated Safeguarding Leads oversee policy implementation, and all members of the school community are expected to promote student welfare and act promptly if a child is at risk.	Safeguarding ISB has developed comprehensive safeguarding policies and procedures aligned with international guidance on children's rights, local legislation on child welfare, and global best practices. A dedicated Safeguarding Committee coordinates all child protection efforts across the school, working closely with administration, counselors, and external experts to ensure that safeguarding measures are consistently upheld and regularly reviewed .
