It provides a long-term approach to the concept of quality, as itincludes, not only effectiveuses or outcomes, but also expecteduses
It places the trainees at the center of the concept of quality andemphasizes their role in the construction of knowledge and quality
It is based on the opinion of real customers, not on the opinion ofexperts, potential customers, or even on the researchers' opinion
The final structure of the dimensions of quality was grounded onstatistical evidence and on data reduction techniques

To develop a measurement model and test a structural model
made up of three constructs that affect the trainees'perception of quality in e-learning: training process, training
attitudes, and training utility
We have used structural equation modeling (SEM) to test the
model with a new sample of data.
