A proposed learning centre will bring together children from the Bushey, Pinner and Stanmore and Canons Park United Synagogue communities.
The plan is for the Aleph Learning Centre NW to open at the beginning of next academic year.
It is envisaged that the cheders of the three shuls will close at the end of the summer term and pupils will have the option of transferring to the new cheder, which will be based at Bushey.
It will be modelled on the successful Aleph Learning Centre at Hampstead Garden Suburb Synagogue.
