The education time was lost during Covid19 pandemic worldwide. During the pandemic period, it became clear even in South Africa that E-Learning was the only alternative for education curriculum continuity. This study aims to validate factors through the reliability and validity of the instrument used to collect data for adoption and acceptance of E-Learning technology system during a pandemic. The questionnaire used was adapted from previous studies and adjusted using a 5-point Likert scale. A pilot study was performed based on 310 responses using cross-sectional design, and the data was analyzed using SPSS version 29 and AMOS. The study used Cronbach’s alpha to test reliability and factor analysis to test the validity. The results showed Bartlett’s Test of Sphericity with significant (p < 0.001), and Kaiser–Meyer–Olkin (KMO) sample size of 0,928 regarded as excellent sample in measuring sample adequacy. The results further showed the Cronbach’s alpha of greater than 0.7, all the factors confirming the reliability of the instrument. The strong relationship of factors was confirmed by factor loadings surpassing the lowest threshold of 0.6. It is concluded that the instrument used in this study displayed reliability and stability. The other methods are recommended for the evaluation of the instrument used for comparison with the results of this study.
