Here is what she says she saw during the tests:

"I have had experience of SATs tests being administered improperly in two schools where I have worked, both in East Sussex.

"In the first instance, in my previous working establishment, the tests were carried out in the main school hall.

I witnessed 'cramming sessions', covering exemplar questions which were almost identical to those appearing on their paper minutes afterwards.

"Myself, and other colleagues witnessed the Year 6 teacher moving up and down the aisles and drawing several pupils' attention to errors that they had made and suggesting that they 'read the question again carefully'.

"This action is highly prohibited in the teachers' guidebook, as is the following example of malpractice which I witnessed very recently in my current place of employment.

"The papers were delivered to the set classrooms where the tests were to take place at least 35 minutes prior to the start time, approximately 8.55am.

"This gave certain teachers the opportunity to browse through the papers, identifying questions that they felt would be a problem for their class.

"I then witnessed them proceed to carry out 'cramming sessions' of approximately 30 minutes, covering exemplar questions which I later discovered were almost identical to those appearing on their paper minutes afterwards.

"Evidently, teachers feel under an immense amount of pressure and are accountable for the success of their pupils in these SATs, but surely, these desperate measures put unnecessary pressure on the pupils, who already have to endure a stressful week of exams.

"Ultimately, the results themselves will not be a reflection of the true attainment of the pupils."
