The technology of nondestructive testing has experienced phenomenal growth over the past two decades and it is expected that this growth will continue for the foreseeable future. The need for training has always been essential to this growth but there was a time when this was not so. In the early days of NDT, training was mostly unorganized and consisted of on-the-job efforts. An experienced practitioner would pass on their skills to a “helper” by the “show and tell” method. There was little to help this effort in the way of training materials. In 1964, a draft document was developed by a Task Group, then approved for publication by the Technical Council for the membership of SNT (prior to the name change to ASNT) to review and comment. That document was referred to as “SNT-TC-1T; the “T” was an abbreviation for “Tentative.” It would ultimately be changed to SNT-TC-1A. The “TC” referred to the Technical Council. Once approved by the board of directors in 1966, the training that was recommended began to seriously be considered as essential to the NDT process.
