Based on the information provided by the research and documented by different authors at national and international level, we reflect on how collaboration and solidarity in teacher professional development can be reoriented and replicated by the whole school community in the education system. At the same time, it can have an impact on students' academic achievement and be reflected in grades or in national or international assessments. I extend an invitation to teachers to use collaboration and solidarity as a tool, not only in their professional development but also within their courses. To act as role models by encouraging such practices with students and the whole school community. Support groups and learning communities should be face-to-face or online, as there is empirical evidence documenting positive outcomes within education systems. What greater pride and satisfaction when we work for the education of our country and can be part of the history and development of our students.
