The University of Bristol admissions controversy refers to an historic dispute over the admissions process for the University of Bristol in the United Kingdom which occurred in 2003.  The 2003 incident was caused by concerns over bias in the admissions system that were perceived as favouritism towards state school students after the rejection of some students with strong academic records who attended independent schools.  The University's widening participation policy allowed the awarding of slightly lower offers to promising applicants from schools with lower academic achievement.  Controversy surrounding this policy resulted in a brief boycott of the University by some independent schools and intense media debate about the fairness of the admissions policy as well as praise and criticism of the policy and the boycott from politicians, student leaders and education groups.  The boycott was lifted after two months when the Independent School's Council expressed satisfaction with the fairness of the admissions system.  Two years later a survey of independent schools concluded that: "It is likely that rejections which may have seemed discriminatory to parents and schools have in fact, been due to a large rise in suitably qualified applicants" and independent evidence was compiled suggesting that claims of bias were wildly exaggerated.  The controversy has now been superseded by the reality that all British Universities have active 'widening participation' policies designed to increase University applications from lower-achieving schools which tend, de facto, to be state schools.

In June 2015, Dolezal came to media attention when her European American parents stated publicly that Dolezal was a white woman passing as black.  Their statement followed Dolezal's reports to police and local news media that she had been the victim of nine hate crimes; however a subsequent police investigation did not support Dolezal's allegations.  Dolezal's critics contend that she has committed cultural appropriation and fraud; Dolezal and her defenders contend her racial identity is genuine while not based on biology or ancestry.  In a November 2015 television interview, Dolezal publicly stated for the first time since the controversy began that she was born white but still identified as black.
