Read the passage and answer the question.

In professional kitchens, apprentice chefs traditionally spent years rotating through stations before earning a place at the pass, learning knife skills and sauce-making through repetition under a senior chef's watchful eye. Culinary schools have long supplemented this model, but some restaurateurs argue classroom training cannot replicate the pressure of a live dinner service. A handful of kitchens have begun formal mentorship contracts that guarantee apprentices structured rotation through every station within a fixed period, rather than leaving advancement to a head chef's informal discretion. Proponents say the contracts reduce the risk that talented apprentices get stuck peeling vegetables indefinitely, while skeptics worry that rigid timelines may push apprentices to the next station before they have truly mastered the current one.
