 In addition, introductory programs are given in advance to each of the 5th and 6th grade classes in the school district, to acquaint the students with some of the material and any special concepts they may need to understand (such as "apprenticeship" in "The Pirates of Penzance" or the British class structure in "H.M.S.Pinafore").Sometimes the children also travel to New York City to see a full-scale NYGASP production.
