The Statewide Course Numbering System (SCNS), a program in the Florida Department of Education, is evaluated. The introduction of the study includes analysis of complaints, old and new surveys, and evaluation concepts underlying the study. Chapter 2 describes the operation of SCNS, its organizational characteristics in the educational establishment of the state capital, and its ties to the 37 public postsecondary institutions in Florida. Major challenges to the existence of SCNS over several years as well as state legislature support are reviewed in chapter 3, which also presents a conceptual framework applicable for analyzing some of the variables that keep SCNS in an unstable relationship with portions of the postsecondary community. Chapter 4 is divided into two parts: the short, medium, and long-range SCNS goals, and outputs of SCNS. The latter are of two types: (1) any statewide three-letter alpha prefix followed by a four-digit number, of which the last three digits are part of a statewide discipline classification system; and (2) products and services provided by SCNS from its statewide course inventory and other information resources. The question about the extent to which SCNS outputs are being utilized within state agencies and institutions is addressed in chapter 5, followed in chapter 6 with the findings from three sets of surveys. Chapter 7 concludes that, among other things: a flat hierarchy should be maintained between the professional staff and the director to encourage communication; the staff of SCNS needs to observe the statutory requirement that faculty committees are to be used to maintain the System; turnover in the lower clerical positions is a constant drain on potential productivity; and there is an immediate need to revive and revise the SCNS Policy Council. Several appendices are included to provide examples of SCNS policies and products and to explain the procedures of the surveys and other data collection efforts. (Author/LC)
