Undergraduate students whose scholarship places them in the top eighth of their engineering class in their next-to-last year or in the top fifth of their engineering class in their last college year are eligible for membership consideration. These scholastically eligible students are further considered on the basis of personal integrity, breadth of interest both inside and outside engineering, adaptability, and unselfish activity. At least 50% of a student's coursework must have been completed by the time of their invitation to the society. Students must be pursuing at least one major within their college's engineering school; for this reason, some Computer Science students may or may not be eligible for membership depending on if Computer Science is counted in the engineering school or the liberal arts school at their respective university, for example. Some chapters may set a scholastic-grade deadline below which candidates are not considered, such deadline being higher than that required as a minimum by the Constitution.
