How a apprentice know when it is their turn for the in school portion of their training?

An apprentice typically knows it's their turn for the in-school portion of their training through a pre-established schedule provided by their training program or employer. They may receive notifications via email or through a dedicated training portal. Additionally, apprentices can communicate with their supervisors or training coordinators to confirm their upcoming school dates. Keeping track of any announcements or updates from the training program is also essential.
