The two bodies responsible for Scotland's curriculum and qualifications are to relocate to shared premises in Glasgow in a move prompted by operational and financial considerations.
Negotiations are continuing, but the preferred location for Learning and Teaching Scotland and the Scottish Qualifications Authority is the Optima Building in Robertson Street.
The LT Scotland offices in Dundee and SQA's Dalkeith centre will be unaffected.
Peter Peacock, Education Minister, said: "It will provide value for money for the taxpayer while also ensuring both organisations can continue to work closely together for the good of Scottish pupils."
Bernard McLeary, chief executive of LT Scotland, said: "The limitations of our current Victorian-era premises have been very apparent for some time.
Co-location with colleagues in the SQA makes a great deal of sense in terms of economics and the already well-established and necessary liaison that exists between the organisations can only be enriched."
Anton Colella, SQA chief executive, said: "This move to new modern premises in Glasgow will help us manage Scotland's modern examination and qualification system even more effectively."
LT Scotland's premises in the West End of Glasgow are currently on the market. SQA's city centre offices are also to be sold.
