As candidates only have to sit two out of the three papers to obtain a result, it is perfectly acceptable for a child to miss an assessments, for any reason. This system allows for situations such as illness, an “off day”, or any prior engagements which cannot be changed.
If you know in advance that your child will not be able to attend one of the assessments you should let the Assessment Centre know.
If your child has been unwell in the days before an assessment you do not need to make a decision on whether or not they will attend any earlier that the morning of the assessment. We would however request that if your child has any ailment which could be passed on to other candidates that you would not send them in to complete the assessment.
If you decide not to send them you can try to inform the Assessment Centre, but please do not worry if you cannot reach them, they will try and get in touch with you if they need to.
