There is no "E-Rate Rule Book"
Rules and guidelines include FCC orders, FCC decisions on appeals, and USAC guidelines and procedures.
The Federal Communications Commission is the rule-making body over the Universal Services Programs including the Schools & Libraries Division (SLD). The SLD program is commonly called “E-Rate” (Education Rate).
The FCC maintains a section on their web site for E-rate news and information related to the most recent Orders, specifically the E-rate Modernization Order (proceeding # 13-184). www.fcc.gov/encyclopedia/e-rate-schools-libraries-usf-program
Forms used by the E-rate program are approved by the Office of Management and Budget. For status of approval of current and prior year forms, enter OMB Control number 3060-0806 in the search field. www.reginfo.gov/public/do/PRASearch
