1. IntroductionTimeline: English higher education (HE) from 1963

• 1963: Robbins Report led to expansion of HE in England• 1986: First Research Assessment Exercise (RAE)• 1992: Abolition of divide between universities and polytechnics• 1997: Quality Assurance Agency (QAA) established to assess HE teaching• 1998: Undergraduate (UG) tuition fees set at £1000• 1999: Tony Blair aims for 50% of young people in HE by 2010• 2003: Colleges of Higher Education allowed to apply for university status• 2006: Introduction of variable UG tuition fees with ceiling of £3000• 2008: Research Assessment Exercise• 2012: Ceiling on variable UG tuition fees raised to £9000• 2013: Research Excellence Framework






1. IntroductionComposition of the English higher education sector

• The current English higher education sector therefore comprises very diverse groups of HEIs:

Pre-1992 universitiesTraditional HEIs including Oxford and Cambridge, and universities established in the 1960s; they offer traditional programmes and subjects and have a research mission

Post-1992 universitiesFormer polytechnics which offer a range of programmes including vocational degrees; some also have a research mission

Former colleges of HEOften small, specialist HEIs; often do not have a research mission; allowed to obtain university status since 2004






2. Efficiency and its measurementWhy measure the efficiency of English higher education?

• Assessing the performance or efficiency of higher education institutions (HEIs) is of interest to: - potential students and their parents - HEI managers- government (since HEIs receive public funding)






2. Efficiency and its measurementOfficial performance indicators

• The Higher Education Statistics Agency (HESA) has published performance indicators since 1999

‘Performance indicators in higher education (HE) provide information on the nature and performance of the HE sector in the UK. They are intended as an objective and consistent set of measures of how a higher education institution is performing.’

The indicators currently cover the following data:•widening participation indicators•non-continuation rates•module completion rates•research output•employment of graduates






2. Efficiency and its measurementOfficial performance indicators

• Research Excellence Framework – REF (formerly Research Assessment Exercise – RAE)- evaluation of research quality in British Universities. The research of each subject is ranked by a peer review panel and the rankings are used in the allocation of government funding.

• Quality Assurance for Higher Education (QAA) assesses undergraduate teaching.






2. Efficiency and its measurementUnofficial performance indicators

• Newspapers regularly provide rankings of higher education institutions (HEIs). For example- The Times Good University Guide- RIA Novosti/HSE ranking of Russian Universities- Forbes ranking of Russian Universities- Times Higher Education World University Rankings- The QS World University Rankings






2. Efficiency and its measurementThe Times Good University Guide: 8 measures• The universities are compared on ‘8 well-established measures of

importance to the undergraduate experience’.1. Student satisfaction 2. Research quality3. Entry standards4. Student-staff ratio5. Services and facilities spending6. Completion7. Good honours8. Graduate prospects






2. Efficiency and its measurementProblems with these rankings

• HEIs operate under different conditions and in different environments.

• HEIs produce an array of outputs from a range of inputs. A ratio of one output to one input is, at best, only a partial indicator.

• What is the appropriate way to combine information across a variety of indicators?

• We need a method for measuring efficiency which takes into account the multi-dimensional nature of production in HEIs.

2. Efficiency and its measurementStochastic frontier analysis (SFA)

Aigner, Lovell and Schmidt (1977)

• The error term is split into 2 components:- a random error component (as in OLS)- a half-normally distributed component to reflect efficiency

5. Conclusions

• Ratios which claim to measure efficiency or performance of universities (such as those found in media rankings) should be treated with caution as they do not adequately reflect the university context

• DEA and SFA can provide multi-dimensional measures of efficiency• DEA and SFA provide different estimates of the levels of efficiency in

English higher education• Policy-makers should be wary of using the DEA within-year estimation

approach• Rankings of DEA and SFA efficiency scores are significantly positively

related, but correlations are low• Merging HEIs appear to have higher efficiency than non-merging HEIs• Further analysis is necessary to discover whether this is caused by the

merger or other characteristics
