The level of job performance, international comparability and competitiveness of Nigerian university graduates are burning issues. Consequently, the academic quality of Nigerian universities has come under severe criticism. Since university lecturers are key players in quality control in universities, this study explored their perceptions of variables important to quality control in Nigerian universities. Five hundred lecturers from public universities in the South-South geopolitical zone responded to a 25-item questionnaire. Five research questions were framed and simple percentages were used in analysing the data. The result showed that according to the lecturers; availability of an adequate number of qualified staff, students' attitude to study, early publication of students' examination results, availability of well-equipped laboratories and workshops, and funding of tertiary education were the most important variables in academic quality control.
