The quality of university life is declining under strain from the higher education, leading independent schools in Britain complained. The warning followed survey of the impressions of campus life gained by students of school. Poor interviewing of the applicants, infrequent contact with tutors, worries over student safety, and even complaint over the food were all seen as symptoms of the pressure on universities. Head teachers said that standards could well drop if the squeeze on university budgets continued. A survey was carried out because of fears that the level of green area in universities had declined. A great number of student suicides had raised concerns among head teachers.
Although most of the 6,000 students surveyed were enjoying university life, almost a third was less than satisfied with their course. About one in 10 had serious financial problems and some gave alarming accounts of conditions around their halls of residence. Incidents mentioned included a fatal stabbing and shooting outside a hall of residence, the petrol-bombing of cars near another residence, and two racist attacks. Nine percent of women and seven percent of men rated security as unsatisfactory in the area where they lived. Salford University had the lowest satisfaction rating.
Lancaster and Kingston universities were rated the safest.
The survey confirmed head teachers’ fears about contact between students and tutors slipping, with a quarter of the students seeing their tutors only every three weeks. New students, used to regular contact with their teachers, found it hard to adapt to the change. Interview techniques were a cause for concern, with the school calling for more training of university staff involved in admission. Some headmasters complained that interviews were increasingly "odd". One greeted an applicant by throwing him an apple. Another interview lasted only three minutes. About a quarter of the students found the workload at university heavier than they had expected. Imperial College London, Oxford and Cambridge universities registered by far the highest workload. There were difference between subjects, with architecture, engineering, veterinary science, medicine and more some science subjects demanding the most work. Veterinary science was nevertheless the most popular subject, followed by physiotherapy and history of art. General engineering, economics, computing and sociology were the least popular. The survey also confirmed previous concerns about possible racial prejudice in admission to medical courses. Applicants with names suggesting an ethnic minority background had been rejected with qualifications as good as successful white candidates.
