The on-going investigation into training malpractice by the SIA (Security Industry Authority) has led to a further 283 certificates being withdrawn. Highfield Awarding Body for Compliance has withdrawn the certificates as the investigation involving AAB Training, Adult Learning Network and Get Licensed continues. Highfield Awarding Body for Compliance has withdrawn the physical intervention unit that applicants took via Adult Learning Network and AAB Training to gain the Level 2 Award in Door Supervision, making the qualification invalid. Of the qualifications withdrawn, 167 had been used to obtain a Security Industry Authority licence. The SIA has written to licence holders to explain that they have 28 days to gain a valid qualification or their licence will be revoked. The news follows an announcement late in 2012 that the holders of 654 SIA licences had been contacted and informed that their licenses would be revoked unless they obtain a ‘valid qualification’ within 28 days of the notice. This followed a move by Highfield Awarding Body for Compliance, also related to the Level 2 Award in Door Supervision, which saw 1,001 certificates a withdrawn. The malpractice has resulted in over 800 SIA licences being issued, following which the holders had to seek re-certification to be able to legally operate. The SIA is currently transitioning to a new regime.
