“The Head of Centre is implicated in the allegations, therefore a potential conflict of interest exists. However, investigators initially conducted an unannounced visit and as the Head of Centre is responsible for ensuring the integrity of Pearson qualifications is not undermined, investigators approached the Head of Centre to respond to the concerns. The second visit to the centre was arranged, however the Head of Centre was not informed of the details of the allegation or the second sample of learner prior to the visit.”
