Allegations of academic fraud have been made against nearly 20 alternative higher education providers in London in recent months, the head of the UK’s standards watchdog has said. Warning that fraud and malpractice now pose a “real challenge” to traditional quality assurance in higher education, the chief executive of the Quality Assurance Agency, said that his organisation had “recently received and, in some cases, investigated allegations about admissions, malpractice, academic fraud and the falsification of evidence in 19 alternative providers in London”.
