Barnet Council has received complaints over admissions to the nursery of Rosh Pinah School in Edgware for September.
The JC has been unable to confirm the reasons for the objections although one local parent claimed that the two-form entry school had failed to abide by its admissions rules. Governors' chair Barbara Hotz was unavailable for comment despite repeated requests.
A council spokesman said: "We have received a few complaints from parents applying for places at Rosh Pinah Nursery School. We are working closely with the school to support them with their admission arrangements."
The school's website lists the admission arrangements as "not available" and the version posted on the council's website is out of date.
Rosh Pinah's principal is Rabbi Yitzchak Schochet of Mill Hill Synagogue, who said the pressure for places reflected "the very real need for another school in the area - something we are going to be very focused on".
