The School was originally founded in 1577, lapsed some time during the Civil Wars and was refounded in 1662. In 1864, it moved to its present beautiful site overlooking the town and the River Deben. The School is part beneficiary of an endowment left to the town of Woodbridge in 1587 by Thomas Seckford, Master of the Courts of Requests to Queen Elizabeth I.
The School is situated in over 45 acres of wooded and undulating grounds within five minutes' walking distance of the town centre. There has been steady expansion and, in recent years, there have been added a Sixth Form Centre, large Sports Hall, Music School, Art, Technology and Science Blocks. The school first admitted girls in 1974 and is now fully co-educational. In September 1994 the School opened a new library, IT and teaching block which gives it facilities unsurpassed by any other school in the region. The IT Department includes two rooms equipped with PCs and Archimedes computers, and all classrooms in the new building are equipped with trunking to allow the use of the latest technology. The Modern Languages Department includes two language laboratories. In 1995 the School opened a floodlit all-weather hockey pitch. The junior school, The Abbey, is nearby, and there is a new Pre-Prep Department for pupils aged 4-6 on the Woodbridge School site.
