This requires both top-down and bottom-up approaches, so that new standards are defined at the systemic level, training is offered by education institutions, skilled teachers can mentor others, and teachers can learn from each other, investigate in collaboration with others and exchange good practices. This makes the teaching profession more attractive, but also much more demanding. Many education systems still struggle to raise the status of the teaching career, so that teaching can be considered a "profession" viewed as having the same value as medicine, law or engineering (Guerriero, 2017).
