PORTLAND North Primary School are calling all past students to join them in celebrating the school’s 150th birthday.

It will be a two-day celebration on October 20 and 21 including an open day, a ceremony, fete, musical concert, activities, a student art exhibition, and historical photos to view.

In the lead-up to the celebration the school is encouraging past students to provide any photos they have related to the school, so they can be used for a 150th memory book which families or past students can then order.

They hope to include historical images, information, documents and other mementos capturing how the school shaped and came to be where it is now.

A sample book will be available to view during the celebrations.

On October 20 the school will host an open day for families from 9am to 1pm, and then a reunion later that night at 6pm.

The next day will kick off at 11am with an opening ceremony before the rest of the festivities begin.

Normally, each year the school runs a fundraising fete to subsidise school camps, but will be this year there are plans for a bigger event during the 150th celebrations.

School principal Cate Elshaug said the annual school concert will also be put in the mix for the birthday.

“The parents club will be heavily involved this year, so it'll be the normal fete but hopefully elevated with a more quality event,” she said.

“The children are learning about the history of Portland and Victoria at the moment so there'll be an exhibition of their history research and staff are going to do a historical display, so old photos, trophies and all that will be all set up.”

There will be food vans, face painting and possibly pony rides at this “bigger and better” fete.

 Once known as Cockatoo Valley School, the facility opened January 1, 1873, ready to give an education to children who lived on the outskirts of Portland.

Despite the building upgrades and name change, Portland North Primary School still prides itself on the same community-rich environment which they will display during celebrations, Ms Elshaug said.
