The National Curriculum assessments have been designed to make sure that as
many children as possible can be assessed. There may, however, be a small
number of pupils who are not able to take part in some or all of the
assessments, even allowing for the full range of arrangements that can be made.
Usually this only happens if all or part of the National Curriculum is not
suitable for a pupil because he or she has certain special educational needs.
The assessments are designed to cater for most pupils with special educational
needs.
