The English Order of the Coif was the most ancient and one of the most honored institutions of the common law. It was an association of lawyers who for centuries had the sole right to appear as barristers in the Court of Common Pleas. The Order takes its name from the word used to designate the cap all the members of the Order were compelled to wear. This cap or coif was originally of white lawn or silk, forming a close-fitting hood. Later when wigs came into fashion, the coif was changed to a circular piece of white lawn fastened to the top of the wig. The real decline in the power and influence of the Order came through the appointment of King’s counsel but despite efforts to change it, the Order remained the sole body of accepted practitioners at the Common Pleas Bar down to the Judicature Act.

The American Order of the Coif is the outgrowth of an earlier society known as Theta Kappa Nu, founded in 1902 for the purpose of promoting scholarship among American law students. In 1912 the society was reorganized as the Order of the Coif “to foster a spirit of careful study and to mark in a fitting manner those who have attained a high grade of scholarship.” Students in the top 10% of their graduating class are eligible for membership
