What are some of the limitations of CAA?

• Construction of good objective tests requires skill and practice and so is initially time-consuming.
  
• Because of the above, testing of higher order skills is difficult.
  
• Implementation of a CAA system can be costly and time-consuming.
  
• Hardware and software must be carefully monitored to avoid failure during examinations.
  
• Students require adequate IT skills and experience of the assessment type.
  
• Assessors and invigilators need training in assessment design, IT skills and examinations management.
  
• A high level of organisation is required across all parties involved in assessment (academics, support staff, computer services, quality assurance unit, administrators.)
