In the late 2000s it was generally taught as a replacement for GCSE ICT, and the GNVQ which had been withdrawn in 2007. DiDA faced controversy in its lifetime, particularly after the Wolf report found that it was primarily being taught by schools because it was the equivalent of studying four GCSEs at once, which had a major impact on league table scores. From 2012 a revised DiDA and CiDA were taught by a smaller number of centres, with the original qualification removed from league table consideration in 2014.
In the late 2000s, DiDA was often used as an alternative to GCSE ICT and the GNVQ, which had been discontinued in 2007. The program faced controversy for being taught by many schools because it essentially covered four GCSE subjects at once, leading to a significant impact on school rankings. Starting in 2012, a revised DiDA and CiDA were introduced by fewer institutions, with the original qualification removed from league tables in 2014.
