Abstract
The measure of quality assurance evaluation plays a vital role in quality enhancement
determinations, precisely in university educational institutions. Recently, Nigeria Government
had to embark on laudable policy programmes that will enhance the quality of university
educational institutions. But to fulfill this responsibility, is frequently thwarted by longstanding
challenges of access, inadequate funding, facilities, governance, curriculum problem,
human resource and technology input. The challenges face by university educational
institutions have led to a rigorous quest for this research. The drive of this research was
accompanied to test and evaluate its psychometric properties of the existing QAEM Input
process (IP) NUC accreditation instruments and as well to examine the dimensionality,
reliability and construct's validity using a confirmatory factor's analysis approach) of QAEM
instruments in order to enhance the quality of evaluation of the nation’s university education
system.
To this end, the research employs a cross-sectional survey data approach collected from the
survey of 16 universities. Data has been collected using the personal contact approach
suggested by Sureshchandar et al., (2004). A total of 1600 survey/questionnaires were
distributed and data has been collected from sixteen universities, which represent one
thousand six hundred (1600) respondents. This is in line with the guideline for sample size
decisions as proposed by Krejcie and Morgan, (1970). The respondents cutting across all
spheres of the university community which includes vice-chancellors (university
administrators), management teams, NUC staff, Teaching staff and non- teaching staff,
director/deans/HODs and students in the North Central Geo- Political Zone of Nigeria.
Nevertheless, these preliminary reports employed quota sampling technique for selecting
survey participants. Factor extracted was achieved using an Exploratory Factor Analysis
(EFA), Principal Component Analysis (PCA)(using SPSS 18.0) and measurement model of
confirmatory factor analysis (CFA) techniques was performed to extract the fundamental
factors, to check for factorial validity of the dimensional constructs and to screen the
instruments into appropriate QAEM dimensions(though Structural Equation modeling (SEM)
using AMOS 18.0.
The findings of this research revealed that all the determinants of the dimensional constructs
for the input process, proposed fulfilled the standard for measuring quality services in
university educational institutions. It was found that the compound reliability, internal
consistency of input process survey instruments evaluated through coefficient alpha and
validity constantly deemed to be important is above the lower recommended limit of 0.7
Nunnally, (1978) which shows that input process survey instruments are internally consistent
and reliable. Considering the overall model fit indices, the equations that describe the model
fit characterize the information well. Hence the remaining fit- Indices show that they are within the tolerable threshold range.
Field of Research: Quality, NUC, MAS, QAEM and IP.
