The George Farmer School first opened its doors just after Easter in 1958 with Jo Fathers as headteacher.


Anyone who has worked or studied there since is invited to share their experiences on Friday, April 25, and Saturday, April 26.


During the two days staff will exhibit memorabilia and visitors will be encouraged to contribute to a record of their memories and experiences of the last 50 years.


The weekend will be capped with a cheese and wine party on the Saturday night and the anniversary will also be marked with a float at this year's Spalding Flower Parade.


As well as celebrating the past the weekend will also see the beginning of next step in the future of the school when its vocational block is officially opened by Baroness Verma, the Conservative spokesman for innovation, universities and skills.


Staff insist that although the times may have changed since the era of beehive hairstyles and teddy boys many things have remained constant throughout the school's history.


In fact many long-serving teachers such as John Ashmole, Paddy Palgrave and Alan Robson have been at the school long enough to have taught the parents or grandparents of present day pupils.


Assistant headteacher Maggie Ward attended the school as a pupil herself.


She said: "Having been a pupil at the school in the 1960s, I was delighted to return as a member of staff last year.


"The school has seen many changes and exciting developments, but its aim of ensuring that every child achieves beyond its potential remains the same."
