Totternhoe Pre-school re opened as part of Totternhoe Lower School on Monday, January 12.
The previously privately run pre-school was forced to close before Christmas because of lack of funding.
Headteacher Olivia Bates, said: “There was lots of fun and games as children old and new came in.
“Many parents commented that they were extremely happy to see the children come straight in and start playing.
“We are over joyed about having a pre school as part of our educational ethos and are relishing teaching children aged 2-9.
“It is exciting because the pre-school children will be able to link with the rest of the school and be part of shows and sports days as well as having a natural progression through to Reception, should the parents and carers choose.”
