Indicators and Computation

Computation

Percentage of international students: This is the proportion of the students in the university who are non-Nigerians. This indicator measures how well the university is able to attract foreign students. The indicator is important in a globalising world and within the context of a university being a universal institution where students from all over the world are free to enrol in the university. It is derived as the percentage of the quotient obtained by dividing the number of non-Nigerian students in the university by the total number of students.

Percentage of international staff: This is the proportion of the academic staff of the university who are non-Nigerians. It is designed to measure how well the university is able to attract and retain expatriate staff. The indicator is important in a globalising world and within the context of a university being an institution with a universal framework of operations. It is computed by dividing the number of non-Nigerian teaching staff by the total number of academic staff in the university and expressing this as a percentage.

Percentage of female enrolment: This is calculated by dividing the number of female students by total enrolment, expressed as a percentage.

Percentage of academic programmes of the university with full accreditation status: This is to measure the overall academic standing of the university. It is computed by dividing the number of academic programmes of the university with full accreditation status by the total number of programmes offered by the university and expressing this as a percentage. 

Percentage of academic staff of the university at full professorial level as of December 31, 2021: This is a measure of the quality of staff and is calculated by dividing the total number of full professors in the university by the total number of full-time academic staff, expressed as a percentage.

Percentage of academic staff with PhDs: This is computed as a percentage of PhD holders in the university of the total number of academic staff in the university.

Percentage of students outside the state where the university is located: This is computed by dividing the number of students from outside the state where the university is located by total enrolment and expressing as percentage. The percentage was supplied by the university. It is a measure of how well the university is striving to avoid localisation.

Percentage of academic staff whose state of origin is outside the state where the university is located: This is computed by dividing the number of staff from outside the state where the university is located by total number of staff and expressing as percentage. The percentage was supplied by the university. It is a measure of how well the university is striving to avoid localisation.

Percentage of students with on-campus accommodation: This is the number of students who are in on-campus hostels divide by the total enrolment in the university expressed as percentage. The percentage was supplied by the university.

Efficiency (Student completion rate for 4 and 5-year degree programmes): This is measured as student completion rate which is a measure of the internal efficiency of the university. Efficiency (student completion rate) for the 4-year degree programme in 2021 is calculated by dividing the number of students who graduated in 2021 (for the cohort that enrolled in 2017) by the total number of students in the graduating class of 2021. The quotient is expressed as a percentage. The same is done for the 5-year programme. The mean of the two percentages is reported for this measure where the university has enrolment for both 4 and 5-year programmes. In an event of only 4-year programmes, no mean score is necessary.

i10-index (last 5years): This is computed as total i10 for the university divided by the total number of academic staff in the university (to obtain per capita i10) and multiplied by 10.

Transparent Ranking: This is obtained from the January 2021 Webometrics ranking and scored proportionately for the analysis.

Quality of infrastructure (from accreditation data): This is the mean of scores returned by accreditation teams for the best and the worst-scoring programmes in the latest accreditation exercise. The mean is computed as percentage.

Community service/university’s contribution to government- 2020: This is scored as percentage by a team of experts and the mean of two experts recorded for the universities which submitted community service data to the online form.

Reputation: This was obtained via a national survey. The mean score of each university was computed and converted to percentage.

Total score: This is the addition of scores of all sixteen metrics. Universities with missing data based on no accreditation scores were omitted from the computation.
