An online contract notice outlines that the government bodies are looking for a variety of computer testing systems, which will be used by millions of people every year.

The DSA's theory test, the certificate of professional competence for professional drivers and the safe road user award will all be incorporated into the new testing services, which will be delivered via 164 test centres across the UK.

The average number of tests carried out annually for the DSA is approximately 1.7 million.

Seperately, the DfE requires the computer-based services for its literacy, numeracy and skills tests, which may also include a human marking element. These may also need to be made accessible to applicants within the EU, where the annual number of tests taken could reach 400,000.

Finally, the UKBA may also require the capability to deliver computer-based tests across a nationwide network of facilities for assessing an applicants' knowledge of life in the UK for naturalisation and settlement purposes.
