The report further revealed that several private institutions with very high fees performed poorly in the ranking with 12 failing to make any contribution to what NUC classified as “knowledge economy.”
The ranking of universities, the Commission explained in the report, is based on several factors.
One is the percentage of academic programmes which is used to measure the overall academic standing of the university, compliance with carrying capacity, the proportion of the academic staff of the university at the professorial level as well as the proportion of the academic staff who are non-Nigerians and non-Nigerian students.
Another is the proportion of staff of the university with outstanding academic achievements, Internally–generated Revenue, research output, student completion rate, doctoral graduate output for the year, stability of university calendar, and student to PC Ratio.
NUC added in the report that in arriving at the proper rating, the computation was based on student-teacher ratio; percentage of full professors; percentage of international staff and students; percentage of programmes with full accreditation; efficiency which is measured as student completion rate; all citations per capita; All h-index per capita; All 1-10-index per capita; Google scholar presence and contribution to knowledge economy.
