Although academic performance remains a common indicator for a school's success, it's no longer the sole criterion; happiness and overall well-being are now recognized as crucial factors as well. Student well-being depends on many factors and schools play a key role to achieve it. Schools can support students to foster resilience, develop positive relationships with their peers and motivate students to strive for their best. Schools are also expected to be prepared to recognise and address issues such as students ‘mental health difficulties (e.g. depression), stress, or demotivation, as these can hinder both academic and future success. But how much do we know about student well-being and how to foster it at school?What should schools do to foster a caring school environment? And what does research tell us about it?   In this course, we will reflect on these and other questions by exploring key insights from The Program for International Student Assessment (PISA). PISA has consolidated data on student well-being through the PISA Happy Life Dashboard. The dashboard considers nine key aspects to student well-being including engagement with school, openness to diversity, psychological well-being, social relationships, and study-life balance.
