Wellbeing

Social and Emotional Learning (SEL)
The school implements an SEL curriculum that begins in kindergarten and continues throughout a student's education. This curriculum aims to teach students skills for building relationships, managing their emotions, and making thoughtful decisions. The "TUSKERS" values (Thinkers, Unique, Supportive, Kind, Exceptional, Respectful, and Sincere) are integrated into daily activities and serve as a shared framework for behavior. This can be seen through reward systems, lessons, and school-wide discussions. The goal is to provide a consistent and clear set of expectations for how students should interact with one another.

Special Educational Needs (SEN)
BASIS does not have a specialized SEN programme.

English as an Additional Language (EAL)
The school does not have publicly available information on their EAL.

Mental Wellbeing
The school's support for mental wellbeing is delivered through a team of staff members. The Student Affairs Department, which includes deans and counselors, is a primary point of contact for student support. Deans are assigned to specific grade levels and monitor student performance to proactively identify those who may need help. Counselors also provide direct support for both academic and personal issues. This system is designed to provide help for students who may be experiencing academic stress, personal difficulties, or other challenges.

Safeguarding
The school does not have their safeguarding policy publicly available.
Parent Experience

History
BASIS International School Bangkok opened in August 2019. It is part of the BASIS Curriculum Schools network, which was founded in 1998 in Tucson, Arizona. The founders, Dr. Michael and Olga Block, created the curriculum based on their observations that students educated abroad were more prepared for university. The Bangkok campus is the first BASIS International School in Thailand and was established with the intention of blending the BASIS curriculum with Thai culture.

Community
BASIS International School Bangkok has an international community with students from over 30 countries and a staff primarily from the United States. The student body is a blend of Thai and international students. To foster a closer community, the school organizes cultural celebrations like the Songkran Festival, which honors local traditions. The school also participates in various sporting and academic events that promote teamwork and community spirit. Additionally, the school holds parent workshops and other events to encourage strong communication and involvement. The goal is to build a community that feels both internationally connected and rooted in Thai culture.

Parent Teacher Association (PTA)
The school does not mention an official PTA, however the school uses email and a platform called Schoolzine for weekly updates and news. In the primary grades, the school uses a co-teaching model where a Learning Expert Teacher (LET) and a Subject Expert Teacher (SET) both communicate with parents. The LET is the main point of contact for a student's overall progress, while the SET communicates about their specific subject.
