What are their current roles?
Any role other than lead classroom teacher is fine.
How many hours a day will be dedicated to Once?
At least 3 hours so they can see at least 10 students (with time for transitions between them).
What will they do during the other hours?
What responsibilities did they have previously that they are giving up?
It is critical that we are explicit about these trade-offs.
Will someone else be covering that responsibility for them now?
Will they get pulled for other roles (ie. substitute teaching)?
They should be protected from substitute teaching.
Who manages them day to day? Who will be the Once point of contact?
Do they have experience teaching reading?
They do not need experience teaching reading.
