Capita, the outsourcing giant paid £107 million to run SATs, has again slashed rates for markers – who say their pay packets remain the same despite a doubled workload.
Technical issues already delayed marking by a week, with some markers unable to access training for the second year.
But teachers employed to mark tests this year say their pay has been slashed, also an issue last year when the company first delivered SATs.
They also warned that big increases to their workload risked rushed marking and a backlog as some walked away from the job.
