 JNET(the Japan NBI Expert Team)was established in 2011 to develop a universal classification of magnifying NBI. The team comprised 38 members from 26 institutions throughout Japan, including the proposers of each of the existing classifications of magnifying NBI.

 The JNET working group held discussions and established common evaluation criteria for VP and SP partially, known as the NBI scale.

 In a previous web-based image interpretation study, we produced basic data for the development of the JNET classification by validating the findings used in the NBI scale, as well as the necessity of an individual criterion. Based on these data, we reached a consensus for the development of the JNET classification.

 Although near-focus(×40 magnification)and optical zoom systems have recently become available, the use of magnified endoscopic diagnosis is not widespread in the Western countries. Therefore, it is important to raise worldwide awareness regarding the newly established JNET classification. The aim of this study was to evaluate the accuracy of the JNET classification using an internet-based e-learning system and to evaluate the learning curve for Japanese and Western endoscopists, including both experts and non-experts.
