Yavneh College has closed early ahead of the summer term after a "large" covid-19 spike saw more than 250 pupils and staff self-isolating.
In a letter to parents, seen by the JC, headteacher Spencer Lewis said the Borehamwood secondary school would switch to home learning this term, which ends on Wednesday.
The decision was made after consulting with the local authority, he said.
“As you will know, we have had a large number of positive Covid-19 cases among students and staff in the last few days resulting in well over 250 pupils and staff self-isolating,” the head wrote.
