CFA attempts to confirm hypotheses and uses path analysis diagrams to represent variables and factors, whereas EFA tries to uncover complex patterns by exploring the dataset and testing predictions (Child, 2006)..

Confirmatory Factor Analysis. Confirmatory factor analysis (CFA) starts with a hypothesis about how many factors there are and which items load on which factors. Factor loadings and factor correlations are obtained as in EFA. EFA, in contrast, does not specify a measurement model initially and usually seeks to discover the measurement model You would not get a test of whether the factor loading matrix conformed to your model. In confirmatory factor analysis (CFA), you specify a model, indicating which variables load on which factors and which factors are correlated. You would get a measure of fit of your data to this model.
