### Abstract

The Danish Upper Secondary School Leaving Examination includes the 3
year A level mathematics course which for the first time in 2001 allowed
schools to chose to allow their students to complete their mathematics
examinations with a CAS calculator. In 2000 and for those not using a
CAS calculator in 2001 it was assumed that all students would use a
graphing calculator. The introduction of the use of CAS calculators into
assessment was the culmination of 3 years of work by the ministry of
education with pilot schools.

This paper will explore the changes that have occurred in assessment
from the use of scientific calculators in assessment through the
introduction of graphic calculators and then finally to the use of hand
held computer algebra systems. Particular reference to the style of
questions used both in the pilot phase and the first examination session
of the computer algebra questions will be considered. The opportunities
for further development of examination questions with the availability
of CAS will also be considered.
