The Jewish organisation said the kindergarten to year 6 school in Giralang was final given approval to open the school after a "rigorous two-year process".

Chabad ACT signalled its intention to open the school in 2018 when it applied for in-principle support to the Education Directorate to apply for registration.

The Canberra Jewish School received the certificate to open earlier this month from ACT Education head of non-government education Lynda Tooth.

The school will complement the established Gan Yisroel day care centre and preschool, which Chabad ACT opened in 2014.

Chabad ACT chairman Rabbi Shmueli Feldman said the school was an essential element for the Canberra Jewish community.

"In Canberra, particularly with its national significance, it is crucial that Jewish families that live and move here have the option for their children to be educated in a Jewish environment and to have access to the same excellent Jewish education being offered in other cities around Australia" he said.

The school has composite aged classes. Chabad ACT said it started intentionally small and it hoped for more enrollments as the year progressed.

Chabad is an Orthodox Jewish Hasidic movement, which is one of the largest Jewish religious organisations in the world.

Chabad emissaries have arrived to help with the school, including Canberra Jewish School head teacher Menouha Wassermen.

Mrs Wassermen said she was "truly excited to be a part of this monumental next step for Jewish continuity in Canberra," and she "looked forward to meeting the local Jewish community and welcoming their children to a school which will offer the best of all worlds in a Jewish spirit".
