Up to 22,000 student appeals will be "severely delayed" after workers voted in favour of strike action, a trade union has warned.
Staff at the Scottish Qualifications Authority (SQA) opted to go on strike after they voted down a "derisory" pay offer that ranged from 1.7% to 4%.
Unite confirmed that the strikes will happen on 8, 15 and 16 September.
The SQA has said it will continue to discuss the pay offer with unions and the Scottish government.
Unite represents hundreds of workers at the exams body.
