This report studies the feasibility of several alternative quadrimester programs for year-round schools and attempts to determine if adoption of such a schedule would be beneficial for the Lafayette Parish school system. In addition to a discussion of the probable educational impact of various quadrimester programs, the author presents an analysis of the anticipated economic costs and benefits of a quadrimester program for the Lafayette Parish schools. The author concludes that, although a quadrimester program will save money in the long run, it will require a short-term increase in school expenditures. The public must therefore be educated about the long-term educational benefits of a quadrimester program, he suggests, if such a program is to be accepted. (JG)
