Teaching Assistants

Each class also has an assistant teacher who works alongside the teacher to provide a nurturing and supportive environment for young children.  Assistants are often recent Bryn Mawr graduates who have previously worked at Thorne and who already understand our philosophy and the way that we work with young children. The assistants must demonstrate a depth of understanding and concern for young children along with some previous practical experience.

Teacher Aides

In addition to the teacher and the teaching assistant, teacher aides provide additional adult support in the classroom. The teacher aides are most often Bryn Mawr or Haverford College undergraduates who have a demonstrated interest in working with young children.
