Online assessment
In its broadest sense, e-assessment is the use of information technology for any assessment-related activity. This definition embraces a wide range of student activity stretching from the use of a word processors to on-screen testing. Due to its obvious similarity to e-learning, the term e-assessment is becoming widely used as a generic term to describe the use of computers within the assessment process. Specific types of e-assessment include computerised adaptive testing and computerised classification testing. An e-testing system designed to focus on lower level associations comprises two components: (1) an assessment engine; and (2) an item bank. An assessment engine comprises the hardware and software required to create and deliver a test. Most e-testing engines run on standard hardware so the key characteristic is the software's functionality. There is a wide range of software packages. The software does not include the questions themselves; these are provided by an item bank.

Onscreen assessment 
Onscreen exams can be held anywhere where there is an internet connection, providing they are run according to the conditions specified by the procedures document for the awarding organisation being used. Centres need to ensure that the latest version of the awarding organisation software is installed on all computers that will be used by learners.
