The nursery, which cannot be named for legal reasons, said: “We were, and remain, deeply shocked, saddened and sorry to learn of the actions of a former member of our staff.
“As soon as concerns were raised, we took immediate action, contacting the police without delay, suspending the individual concerned, and fully cooperating with the investigation.”
It said a full review had been carried out and its safeguarding policies and staff training had been strengthened.
Jonathan Hulley, Surrey County Council cabinet member for children, family and lifelong learning, said he was “appalled” by the crimes committed by Waller.
“The wellbeing and safeguarding of children and young people is our absolute priority,” he added.
Waller was found guilty of rape, two counts of causing or inciting sexual activity and taking indecent photos after a trial at Staines Youth Court earlier this year.
The offending happened at a nursery in Surrey between July and August 2024.
