The school will hold its centenary celebrations, and all former students, staff and community members are welcome to attend.

School administration manager Sue Richard is coordinating the centenary celebrations and is excited about the day's events.

Ms Richard is the second-longest-serving staff member at Kitchener Public School, having worked there for 19 years, with stage one teacher Sue Firth starting six months earlier.

"I've been looking forward to this (the centenary) for a long time, I've got a real interest in the background and the history of the school," she said.

Ms Richard said a provisional school operated out of a hall owned by a miner, located near the poppethead at the Aberdare Central Colliery for two years, while the miners petitioned for a public school to be built in Kitchener.

The public school was officially approved in December 1919, which is recognised as the school's year of birth.

The original building, which still stands today, was opened on August 2, 1920.

The school has expanded to several more buildings, with a current student population of 80.

Ms Richard encourages all former students and staff, and anyone who has had a connection to the school to come along and join the celebrations.

"It's a small community, with a lot of history and traditions," she said.

"We like to share our lovely school with the community."

Students will take part a range of 'Now and Then' activities in their classrooms, showing how education has changed over the past 100 years.

Kindergarten students will be exploring old and new toys; stage one will do basket weaving and peg dolls, stage two will make damper and stage three will showcase virtual reality technology.

Old-school sporting activities including marbles, hopscotch, knuckles and skipping will be incorporated into the day's program.

An afternoon tea for parents and visitors will take place at 1.30pm, followed by a formal ceremony and proceedings at 2pm.

Mugs, pens and a history booklet have been produced for the occasion.
