This paper questions the prevalent approach in assessing the value of e-learning through the information system model. A recall is made of the evolution of DeLone and McCain model and other theory at the basis of such assessment, namely TAM derived models and performance models. In these years of covid which imposed e-learning on schools, without adequate preparation this examination is more than ever important since it changes the logic of the assessment. The covid19 caused an unvoluntary use of e-learning that questions the validity of prevalent models. An integrated model, which take this aspect into consideration, is proposed in this article, to be validated empirically in a soon future.
