Very good School, it is because of the dedicated teachers and a very warm , loving,hard working principal Ms. Cranna. She knows each kid by the name. She greets the parents , she is there in the morning and the afternoon at the school gate helping the kids and ensures safety at all time. PTA here is very hardworking, tries to take advantage of every possibility to raise money for the school activities. There is a green environment strongly preached, which is obvious with the garden that has vegetables, flowering plants, fruit trees grown with the help of little volunteers- the students of Jefferson. The kids come home with a lot of enthusiasm and narrate what they did at school. There is hardly any day my little ones have had a low moment at school. There is parent involvement, parents can go volunteer in their childs clasroom by signing up at the office. There are educational field trips to various places in and around San Francisco. Even the K kids get an opportunity to go overnight camping. Fun!
