and other higher education providers charging less. Postgraduate fees vary but are generally more than undergraduate fees, depending on the degree and university. There are numerous bursaries (awarded to low income applicants) to offset undergraduate fees and, for postgraduates, full scholarships are available for most subjects, and are usually awarded competitively. Different arrangements apply to English students studying in Scotland, and to Scottish and Welsh students studying in England. Students from outside the UK and the EU attending English universities are charged differing amounts, often in the region of £5,000 to £20,000 per annum for undergraduate and postgraduate degrees. The actual amount differs by institution and subject, with the lab based subjects charging a greater amount. The gap between rich and poor students has slightly narrowed since the introduction of the higher fees. This may be because universities have used tuition fees to invest in bursaries and outreach schemes. In 2016, The Guardian noted that the number of disadvantaged students applying to university had increased by 72% from 2006 to 2015, a bigger rise than in Scotland, Wales or Northern Ireland. It wrote that most of the gap between richer and poorer students tends to open up between Key Stage 1 and Key Stage 4 (i.e. at secondary school), rather than when applying for university, and so the money raised from tuition fees should be spent there instead. A study by Murphy, Scott-Clayton, and Wyness found that the introduction of tuition fees had "increased funding per head, educational standards, rising enrolments, and a narrowing of the participation gap between advantaged and disadvantaged students". Adult education Adult education, continuing education or lifelong learning is offered to students of all ages. This can include the vocational qualifications mentioned above, and also: One or two year access courses, to allow adults without suitable qualifications access to university. The Open University runs undergraduate and postgraduate distance learning programmes. The Workers' Educational Association offers large number of semi-recreational courses, with or without qualifications, made available by Local Education Authorities under the guise of Adult Education. Courses are available in a wide variety of areas, such as holiday languages, arts, crafts and yacht navigation. Qualifications Frameworks The two qualifications frameworks in England are the Regulated Qualifications Framework (RQF), for qualifications regulated by Ofqual, and the Framework for Higher Education Qualifications (FHEQ) for qualifications granted by bodies with degree awarding powers, overseen by the Quality Assurance Agency.
