Some schools will receive key stage 2 SATs results in the last week of their summer term because of disruption caused by the coronation of King Charles.
The Standards and Testing Agency has announced schools will receive results and headline data will be published on Tuesday July 11, a week later than planned.
The date of tests were shifted by a day each because of the extra bank holiday on May 8.
The organisation admitted the change may impact schools whose summer holidays start in early July, or “where schools have events booked in the week results will now be returned”.
Although the summer term is not due to end until later in the month in many areas of England, some will break up just days after results are issued.
