Hundreds are expected to celebrate 75 years of Clutha Valley School this weekend.
Jubilee committee member Camille McAtamney said 367 people had registered for the event.
The celebrations begin tonight with a ''meet and greet'' at the Clutha Valley Community Centre.
The formal programme begins at 1pm tomorrow with singing, cake-cutting and the unveiling of a commemorative plaque, followed by photos and afternoon tea.
A jubilee dinner will be held at 6.30pm at the Balclutha War Memorial Hall.
The event finishes with a family picnic on Sunday. Clutha Valley School opened as a district high school on February 1, 1939 with 154 pupils, following the merging of eight schools - Awamangu, Clydevale, Greenfield, Popotunoa, Pukepito, Puketi, Waitahuna West, and Wharetoa. They were joined by Taumata School in 1946 and Tuapeka Mouth School in 1949.
The secondary school closed in 1967, leaving students to travel to South Otago High School in Balclutha.
The school, now called Clutha Valley Primary School, has a roll of about 120 pupils from new entrants to year 8, with five fulltime teachers and three teacher aides.
