They should not be given the most difficult students (which often happens) their 1st year. They shouldn’t be coddled;they need time to learn.
They need a mentor who has time enough to come by and answer the questions the new teacher doesn’t know they need to ask yet. They need only one or two preps so they can get used to how school works.
a mentor than balances being helpful and supportive, but doesn’t make you feel like less of a person/teacher in their critiques
