How would you place a long-term sub position on a resume? Would it get a seperate entry from the districts? I was a long-term sub (20 days max) for a special education position at an elementary school. It was a great experience and it can't go further than 20 days because of the way that the sub permit works Also, can I ask the teacher's assistant for a letter of recommendation? I am also asking the Principal too. But I also feel that the teacher's aide (who has been through at least two other subs) would also write a great letter because they have been in the classroom with me on a daily basis.
