„Although the majority of teachers in most OECD countries enter the profession after having completed a tertiary teacher education programme, some countries, including the United States, have seen a growth of ‚alternative pathways‘ to teaching over the past decades. This includes alternative certification processes, which tend to involve short-term trainings lasting anywhere from a few weeks to a few months or employment-based residency training.“
