The New Youth Entrepreneur curriculum is a series of 12 youth-oriented educational modules containing instructional materials, learning activities, and checkup exercises designed to teach students key elements of entrepreneurship. This document is the twelfth module, and discusses the usefulness of a business plan for entrepreneurs starting small businesses. The first section reviews the importance of developing a business plan for new businesses or for major modifications of existing businesses. The following sections then describe the components of a business plan: (1) a description of the nature of the business; (2) the qualifications of those running the business; (3) the nature of the competition; (4) a plan for marketing, including deciding who the target audience is, what information they will need, and what sales tools to use; (5) the accounting system that will be used; (6) a determination of the costs of getting started; and (7) projections of revenue, costs, and profit data. Finally, sample forms are provided for students to develop their own business plan. (CELCEE, an Adjunct ERIC Clearinghouse on Entrepreneurship Education) (MAB)
