These volumes update the three previous editions (published for 1976-77, 1978-79, and 1986-87) by describing school finance programs in 1990-91 in the United States and Canada. This effort is descriptive, rather than prescriptive. The volumes consist of two major parts. The first part provides an overview of the school finance systems in the two countries. The overview draws primarily on information in the state and province descriptions in the second part of volume 1 and all of volume 2 but is supplemented where appropriate by information from other sources. The revenue of U.S. public elementary and secondary schools was $222.7 billion during 1990-91. Nearly half this revenue (48.3 percent) was provided by state governments, 45.5 percent by local governments, and 6.2 percent by the federal government. Revenue per pupil varies from $9,447 in New Jersey to $3,341 in Utah. Information in the state description section is highlighted in a series of tables covering basic state support programs, local support of schools, capital outlay and debt service, transportation, special education, other selected categorical programs, and teacher retirement programs. The second part consists of descriptions of the school finance systems in 49 states and 10 provinces. No description was obtained from West Virginia. This section closes with a listing of state and provincial education department contacts. Numerous tables and figures are included. (MLH)
