Chapter of Chimes Junior Honorary, founded in 1948 as a women's group, is a group of juniors who share values of scholarship, leadership, and service. Each class works together for one year on programming for Wash U's campus, the internal Chapter, and the chosen partner philanthropy, with the freedom to follow their path for the year. Each member has a name assigned to them that represents an aspect of what they bring to the Honorary (such as intrepidity or flair). Their main campus program is Chimes Week, which explores a particular theme. Like ThurtenE, Chimes has been co-ed since 1991. Yale University The term "secret society" at Yale University encompasses organizations with many shared but not identical characteristics. The oldest surviving undergraduate secret societies at Yale parallel various 19th-century fraternal organizations. In the traditional Yale system, societies were organized by class year. There were two, (then three), senior societies, three junior societies, two sophomore societies, and two freshman societies. All the societies were independent, all had their traditions, and each class-year pair or trio shared common traits appropriate to their class year; the freshmen societies were rambunctious and owned little real property, the sophomore and junior ones were progressively more elaborate, (the sophomore ones regularly maintained live theater in their halls), and the senior ones were extremely small and elite, and with quite expensive property and celebrations. Each of the societies had a link in the class year before and after it; that is, members of one freshman society would all get elected to the same sophomore society year after year, and so on, so that there were two or three parallel sets of linked societies. From time to time, there would be a coup, and one society would break the pattern, forcing the other societies to likewise change election strategies, or cause the creation of a new society. Delta Kappa Epsilon, a junior society, was created in reaction to a botched election process to the junior class societies in 1844. This process held from the 1840s to the 1910s. This system kept Yale out of the more typical intercollegiate college fraternity system, although some regular college fraternities were created out of the Yale system. Yale-type class societies also extended across northeastern colleges. This system has not survived the introduction of regular fraternities and other changes. The senior-class societies continue to prosper today without any of the lower-class societies. A
